Lenses / Re: +18 AFMA out of the box....return?
« on: May 17, 2013, 01:52:28 AM »
Sorry jdramirez, that doesn't really make sense to me.

AFMA is used to correct for manufacturing tolerances. Tolerance means that nothing can be made to an exact value but it can be made for sure within certain boundaries. Canon knows these boundaries for their lenses and cameras. I believe when they allow AFMA to be set from -20 to +20 it should be enough to correct worst case scenario. I don't know that for sure but it would be logical from my point of view.

E.g: The maximum amount a camera can be "off" would be +/-10 and the maximum amount a lens can be "off" would be +/-10 so a correction of +/-20 would be sufficient.

In this case the lens is probably off -9 and the body -9 (so they are both around their extremes) but you can correct it by using +18. Due to the known tolerances your next body will not be off more than -10 so correction should always be possible.

You - Ewinter - could test this by looking at the AFMA values of your other lenses. If you have a big enough amount of lenses you should see a tendency of AFMA values around +9 or at least they should be quite consistently >0. If you can't see this and the values are for example around -15 then there is probably something wrong with your lens.

Lenses / I can't stop thinking about A MONSTER! Part 2
« on: April 18, 2013, 03:47:39 AM »
Hi folks!

Some of you may still remember my original post on this topic from about two months ago (http://www.canonrumors.com/forum/index.php?topic=12825.0). In short I asked about some opinions whether to get a 500L II or not. In this post I’d like to give you a heads up on what happened in the meantime.

To cut a long story short: I got it.
A local dealer made me “an offer I couldn’t refuse” which was a very good price AND the 1.4x III included.

This is not going to be a review but a little report of my experiences with the lens so far – so if you also like to dream of a big white or if you think about getting one this might be helpful to you. If you’re not interested in that, feel free to skip to the end of this post and see some pictures! Be warned that this text is exclusively about using this monster in the field and it does not contain any pixel-peeping.

So…where do I start? If you read my original post you know I had it divided into some major concerns. I would like to continue with this style and tell you how it turned out for me.

WEIGHT AND SIZE OR HOW TO HANDHOLD A BIG LENS
As I mentioned in my first post I was planning to use it exclusively handheld because of a lack of tripod / head and for portability reasons. When I unboxed the lens … well it was probably a little bigger and heavier than I remembered it from the shop ::). I had some serious concerns if this was not too much for me. I tried it out the first time the next day and felt that my arm would probably come off over time. Especially the stress on my wrist joint was high since I held it on the tripod foot with the hand bent ~90° to the forearm. Additionally I had to twist my forearm for this holding method which resulted in some real pain the day after shooting and a forced pause of several days. Holding the lens on the barrel achieves nothing and has the additional disadvantage that you need to lift your left arm even higher to get the lens leveled (and you probably can’t support your arm on your body anymore). These are pretty much the methods of someone who has no clue/experience on how to hold a big lens since it’s the right way you would hold a lens of “normal” size. I have illustrated it in the pics below so that you can better understand what I mean. After a few painful and exhausting shooting sessions I refined my technique and came up with the following solution: Support the lens foot only with the palm of your hand and use your fingers to hold the barrel (right picture). Doing so solves three major problems:

1. Your wrist is only slightly angled and so the force is transferred to your arm in a more natural way.
2. Your forearm is not twisted and will be able to hold more load or the same load for a longer period of time respectively.
3. You gain full access over the lens controls. Use your thumb for pressing the AF-stop button and to manual focus farther, your middle finger for the playback ring and your ring finger to focus closer.

(Btw. you understand me correctly – I do not only use this lens handheld but also with manual focus if needed.)

[I didn't figure out how to put the picture here - it's at the end of the post!]
 
For beginners I recommend keeping the lens foot locked – which will limit you pretty much to taking pictures in landscape orientation. Expert mode is to unlock the foot and to only use the notches to hold the lens exactly horizontal/vertical – this will allow you to change between landscape and portrait just as you would on a tripod, but it surely needs some training (this is the way I mostly do it now and it works very well).
With this technique my problems are gone. Last weekend I visited the zoo and shot about from 10am continuously to 4pm only using the beast and the next day I felt … nothing. Everything is perfectly fine with my arm. I can shoot all day long with it now – of course I can’t hold it to eye level all the time and have to pause frequently but I can’t say that I have missed a shot due to exhaustion – at least none that I wouldn’t also have missed using a tripod/monopod. Did you see my arm in the picture? Yes, that’s all I have to work with and I handhold this baby perfectly for hours, so you can easily too – using proper technique of course! If you are a stronger guy than me you probably can also handhold the 600 II or the 400 II but I don’t have any experience with them and other factors such as weight distribution will play a role.

Weight is in my opinion absolutely no concern when carrying the lens in a backpack. I use the Lowepro Flipside 500 AW which conveys the weight to the hips and not the shoulders if you set it up correctly (which is important for you backbone health) using its hip strap. However, size is a concern but the Lens fits in the backpack nicely with camera attached and also leaves some room for other lenses/accessories. With extender and camera attached it doesn’t fit or it would probably fit if you used some force which I don’t.

CONSPICUITY
Well, there’s nothing you can do about that I guess, this lens draws some serious attention. When I go shooting usually always someone starts talking to me or asks me some questions about it – people are usually quite amazed when they see this monster (and who can blame them?). When I was at the zoo I heard about 100 times people talking behind my back. Somehow this is a little like the weight issue – it is a bit shocking at the beginning but you get used to it pretty fast and additionally >99% of the comments are really positive. I decided to answer questions politely and patiently (about how much it zooms for example ;-P) or sometimes to not give a f*** and this works pretty well for me.

IMAGE QUALITY
Lol. Nothing to do here ::). Think about the best possible image quality you can imagine – this is what you will get from this lens. Sharpness and contrast are perfect and bokeh is creamy – what else do you desire? Did you see the MTF-chart? It’s the only one that I can draw out of my mind since it is only a straight line at 1.
I practically can’t tell the difference in shots with the bare lens and shots with 1.4x Extender used, besides of the even thinner DOF (and stronger bokeh). It is surely measurable (your turn pixel-peepers) but not noticeable with the naked eye I would say. With extender it’s still at least as sharp as every other L lens I own (700mm f5,6 is a KILLER LENS with massive reach btw. ;D).
I wonder how it will be with 2x III but I’m sure it won’t disappoint.

AUTOFOCUS
On the web I read that the AF was “instant” or “blazingly fast” or some other superlatives. To be honest I cannot notice it to be faster than the AF of some of my other lenses eg. 70-200 4 L IS or 100L (with focus limiter activated!). However, this is very fast.
There is one problem I noticed: When my 5D3 goes to sleep and I half press the shutter button it takes about 0.5 sec or even longer (which is an eternity in some action situations) for the AF to kick in. This is a problem of the camera not the lens but I recommend to make sure that your camera doesn’t go to sleep when you want to shoot action. BIF come closer a significant distance during that time span.

STABILIZER
The IS is one of the most important features for me, since it vastly increases handholdability. Using Mode 1 you can frame static objects perfectly and your viewfinder keeps still quite nicely. However the new Mode 3 is my favorite since it doesn’t interfere with my framing in action shots and if you are panning it only stabilizes normal to your panning direction. I have no idea if those claimed 4 stops are true but it simply works great.


SUMMARY
If you are mad enough to buy a lens like this you should really know what you are doing. This is not for the casual weekend shooter. You really need to show some effort and dedication to justify the price tag and to haul this thing around the whole day. But if you are serious, I can’t think of anything that can give you more pleasure to use and more spectacular results than a supertele lens. You wouldn’t believe how happy I am with this “monster”. I’ve only used it since about one month and I'm learning a lot every session, but I think that I was already able to make some really cool shots with it – see for yourself in the link below!
IQ is perfect, handling is very good, you don’t need a tripod if you know how to handle it – believe it or not I’m pretty much using this as my walk around lens now. You can read about IQ, IS, AF etc. in all the reviews you can find, but let me assure you once more that this lens is really handholdable for extended periods of time, since I didn’t find a review who stated that clearly.

Ok, now let’s come to the fun part: PICTURES!
Pictures OF the lens: https://www.dropbox.com/sh/e8dsgdawaxbe2p7/5qjI8NJHBh
Pictures WITH the lens: https://www.dropbox.com/sh/zspwh97zbjbv7ff/t_y_bdpwDQ

Some of those where made with the 1.4x III, some without – consult the EXIF data for more info. Usually the pictures are downsized to about 6MP which is more than enough for everything except very large prints. 5D3_8529 is a 100% crop with the bare lens.

I hope you enjoyed my “not review” and if you have questions don’t hesitate to ask!
Greetings!

Lenses / Re: Which supertele?
« on: April 15, 2013, 02:09:44 AM »
I use the 500L II since about two weeks frequently and exclusively handheld -> works very well for me.

So you took the plunge on "the monster"?

As did I.

I did indeed. And I'm going to post a detailed report on that soon...  ;)

For sports: 300 perfect, 400 perfect, 500 good
For wildlife: 500 perfect, 400 good, 300 probably less than good
For handholdability and transport via backpack: 300 perfect, 400 bad, 500 good

Since you weren't very specific about your needs I can't give you a clear recommendation.
I use the 500L II since about two weeks frequently and exclusively handheld -> works very well for me. I don't have any experience with the 300 and 400 though.

Canon General / Re: Which eye do you shoot with?
« on: March 14, 2013, 11:05:08 AM »
Left eye when shooting in landscape orientation (so that the nose doesn't touch the display) right eye when shooting in portrait orientation (same reason). Sounds complicated but works very well after you get used to it.

Lenses / Re: Bridge not sharp - why?
« on: March 11, 2013, 02:57:58 AM »
After inspecting the full-res image I'm pretty sure that there is no motion blur involved.
The Lens is either bad or misfocused. Luckily this is pretty easy to find out:

Make a picture of something (preferably something flat) by using manual live-view focus with magnification. When you can't get sharp results then there is something wrong with the lens.

You will play with the camera for 10 minutes and never think of the cost laid out again. I promise you that!

I'm using this function since I have my 5D3 - I think I read on the Internet how it works not in the manual. This is my most important and most used 5D3 AF-functionality especially for action. Please note that although you can only set one point as your "home point", if you swich to AF area selection (after setting the home point) you can quickly select different AF areas.

To use this function you have to set your button layout (I think via custom fcn. OR via Q) so that your AF-ON button focuses on your HP (home point).

I frequently use this to focus on the left side of the frame via half pressing the shutter and to focus on the right side via pressing AF-ON. If you don't set a home point, the AF-ON button focuses on the center AF point (or area if AF area is the current AF mode).

You didn't mention that for erasing the HP setting you need to press the AF-point-selection-button and hold it, then press the button left of the light bulb button (I don't have the camera with me and I don't remember which button this is).

If someone needs help with it leave a comment for further explanation.

In the comments to the OP's link someone says something like those DRev guys don't even know the difference between a dSLR and DSLR. Me neither.

Does anyone have an idea what the difference is?

Pricewatch Deals / Re: Need help to determine this deal !!
« on: February 28, 2013, 01:43:45 AM »
Hi,

when you get the same price from a respectable dealer i would strongly advise you to buy it there. Those accessories listed are crap and no way worth it taking any risk. In my opinion it's no use buying a Pro camera with a pro lens for >$3000 and then using worthless junk as tripot, flash, (slow/unreliable) memory card etc.

If you want a tripod - get a quality tripot, if you want flash - get a quality canon flash. It may seem expensive to invest another $1000 in accessories but in the end it will be WAY cheaper since you will not have to buy twice. And don't forget to think about the environment too!

Traumflieger is one of the worst sources for reviews that exists. It's aimed at the very low level consumers who don't leave FULL AUTO Mode.
If you want reviews goto the digital picture or dpreview or photozone.de but NEVER Traumflieger.

And-Rew:

Thanks for bringing this thread back on track by contributing the first on-topic post since a few days...  ;)
Actually after (shortly) trying out the similar sized Sigma 500 this week I'm completely with you on the weight issue. Its far less than I expected at the beginning. Absolutely no problem to carry around in a backpack (that brings the weight to the hips) and probably no problem to carry in my hands for extended periods of time. Holding it to eye-level without support will still be a different story. But I'm sure I can find something to rest my arms on.

It's very common to take a spill on a bike, and just one would wreck that lens.

I had two accidents in the last three years (since I'm going by bike regularly) - both within the same week. It was wet, there were some leafs on the ground, I was going too fast... you know the story.  ::)
I don't make those mistakes when carrying expensive gear so it's not very common to take a spill for me, plus canon claims that the V2 has "twice the impact resistance" than the V1. Of course I could get hit by a car - but my gear wouldn't be my first concern then.

Rat: Thanks for the hint but the weight will be no problem for my bike.

Man up and buy it ffs.

Couldn't you have told me this right at the beginning - then we could have spared ourselves the trouble of this huge thread...  ;D

---------------------------

At the moment I clearly tend to the buying side. I will not get it before April though, so I have still some time to think about it.

The Sigma 500 has a problematic aperture for autofocus.  f/4.5 means that a 1.4xextender gives an aperture greater than f/5.6 so in order to use it you will need a 1D or have to wait until after April for the 5D III to have a firmware update to go up to f/8 for AF. The extender won't give AF on other models. A 2xextender will give f/9, which will not autofocus on any Canon.

Thanks, but I'm not considering the Sigma (I can see now my statement from yesterday was quite misleading - Sorry). I was only trying out the weight of the Sigma (since it is the same as the Canon) at the shop yesterday. Didn't feel so bad and wasn't as heavy as expected after all! After trying I can really imagine to use it handheld.

Cervantes, how could you not believe in crop factor reach advantage???  The only reason to not use it, is in low light...which...well...I agree is more fun.  More wildlife comes out, the light is more interesting, etc.

I had APSC (550D) and I have FF (5D3) and I can assure you that the former hasn't any advantage regarding resolving power than the latter, regardless of ISO. Actually it's the other way round. An APSC-sized crop of the 5D3 shows at least the same level of detail then an uncropped 550D image, despite having vastly less MP (8.6 vs 18MP). I have done lots and lots of macro shots with both cameras and before i got the 5D3 I was concerned about losing max. magnification - that didn't happen.

If reach is this critical to you, I strongly suggest you pick up a 7D or wait for the 7DII
A 300 f2.8 IS FoV on APS-C = 480mm

It'd be $$$ smart + leagues more portable.
My ¢¢

Thanks for the input, but i don't believe in crop factor reach advantage. Furthermore the 300 f2.8 isn't cheap either and the money one loses on a semi-pro body is in the long run about in the same league than on a supertele.

Would the new EF 200-400 IS (forthcoming) be something for you? It has a built-in 1.4x converter, so you can have a 560mm lens if you wish. Don't know about the price.
You make some very good pics, why not try to sell some? At least you could earn some money back.
I am curious about your cycling. Austria is a mountaineous country, do you avoid high places altogether or do you have 24+ gears or what? I could not imagine myself cycling in Austria but then I am from Holland which is a flat as a pancake (and ideal for cycling in my opinion).
Kind regards,

Rob.

Hi Rob,

well i don't really see the advantage compared to the 500. My major concerns - size and weight - will be about the same (or maybe more?) and price will also be higher i suppose. As already said I don't need a zoom - i need reach. 500 seems to be the better option for me in all categories.

I don't know about selling pics. Who would like to buy those?  ::) Also, I like to photograph - I'm not a marketing guy...

About the cycling: In the part of Austria that i live now it's rather flat so cycling is a relatively fast and convenient method of transportation (especially within the city). Otherwise you are right - I'm originally from the province Tirol where this is a complete different thing...

.
If you get the lens, may I borrow it next time in Austria??

Heck with that.  Your girlfriend got a sister???? ;D ;D

Borrowing: ...  ::)
Girlfriend's sister: No, unfortunately she doesn't have sister. She has a brother though so if the lens is worth it to you...  :P

I have the 500mm II and the majority of the time I use it hand held on a FF.  Besides 500mm being my preferred focal length, the weight was one of the reasons I chose the lens over the 400mm and 600mm II's (it's not a massive difference, but it is noticable).  I walk with the 500mm on a BR strap for several hours without issue.  I've never been a big tripod user...although a good tripod/monopod does help to stabalize this lens for those times when you are more stationary.  Oh yes the IS is remarkable...I've shot stationary subjects at 1/20th with great results.  I still use my 300mm f/4 IS with a 50D for those times I want less weight (and less attention) the 500mm will certainly get you some looks.

Thank god I'm not the only one considering to use this handheld. Good to hear that it's possible. You wouldn't coincidentally have some pictures to share would you?  :)

Quote
LOL! Well, you guessed wrong! And the funniest thing is: My girlfriend totally approves this lens. If it was for her I would already have it - she even offered to pay for it! I know I'm a lucky sob...

lol...thats awesome! get it, it might turn her on.

my wife still insists that the first time she saw me shoot with my hasselblad she thought it was sexy. cant say i blame her but it surprised me a non photo person would think of it in such a way.

she still says i shouldn't sell it every time i have thoughts of cashing it out.

 ;D I have never thought about that effect. I'll definitely consider this when making my decision...  ;)

-----------------------------------------

Meanwhile I found out that a local photo-dealer has a Sigma 500mm 4,5 on display. That lens is only a few cm smaller than the Canon and has nearly the same weight. I'll pay him a visit this week and will try to find out if the weight would work for me. If it does, the probability that I buy the Canon is quite high.
I'll of course post some images in case I really get it.

Thank you all for your help!
