Software & Accessories / Re: Long exposure photography
« on: November 28, 2013, 09:39:55 AM »
You're absolutely right of course, any way at all that you can restrict the light from reaching your sensor will necessarily require a slower shutter speed to obtain a given exposure. So cracking-down on your aperture all the way & slapping-on a 2x TC will certainly give you a longer exposure time, but the resulting hit to your image quality will likely be pretty high... To minimize diffraction (& maximize sharpness) I try not to crank down my apertures any smaller than f/16. And I'll only use a TC if the "field of view" demands it.

If you just have to have that extra 3-stops of exposure time (from f/16 to f/64), I'll again urge you to consider stacking an additional filter on top of your Big Stopper. To achive that additional 3-stops I'd use my Lee 3-stop 4x4" glass filter http://www.bhphotovideo.com/c/product/491473-REG/LEE_Filters_9NDG_4x4_Neutral_Density_ND.html; which is a bit expensive, but the resin filters are almost as good and much more reasonably priced.

Of course, if I forgot my extra ND filters (or I'm just too lazy to walk back to the truck) I'll do what ever I have to do to get the long exposure time that I want -- I'll use a polarizer even if I don't really need it, I'll crank-down the aperture to a ridiculously small size, what ever it takes...

Yeah, diffraction worries me too, but I will get to see how bad it actually is for different scenes. I am getting a .6 ND as well as part of the startup kit, so I´ll get an additional two stops there. I agree that stacking is probably the way to go, and that is probably where I will end up finally. Nevertheless, I will experiment with all kind of stuff (using the EC for instance) and see how my pictures are punished. I have also surmised that there is a limit to how many filters it is wise to stack given its impact on IQ, so I given the need for extra stops will probably have to cough up for some expensive high stop filters (hence the alluring Z system;)


With very good filters I'd probably only stack two or three max. Also I'd try and keep the aperture at around f/8 - 16 maybe f/22 if really required. It also helps to shoot on cloudy or slightly dullish days rather than bright sun. Shoot late afternoon and blue hour to get some color in your shots.

I'm getting into long exposures myself. Just recently bought a ND400 just to experiment a bit. If I like it I might buy into the more expensive stuff.

EOS Bodies / Re: Two New Full Frame Cameras in 2014? [CR1]
« on: November 28, 2013, 08:53:23 AM »
The 5D3 will be 2 years old next March, which isn't that far away. We can likely assume that there will be at least an announcement of a 5D4 later on in 2014, can we not? Isn't that one of the full frames? The other would be the high megapixel studio beast 1DXs.

3 years does seem kinda short for the 5D line to be upgraded though. 2 years seems very unlikely so I think we can rule out a 5D4 coming next year!

Could there be something FF that we haven't seen before? What could that be? I just want this year to end so I can find out already!  ;D

Sell sell sell! Get rid of the ef-s lenses while you still can. They're dropping in price nowadays. I assume you bought a 6D for improved IQ. Once you start using it you'll not want to use anything else!

I kept my 7D only as my back up and it rarely gets used now. The high frame rate of the 7D still appeals to me though and I want to keep it. However, I see no adv for you to keep a t4i.

If you decide down the line you need a back up you could always just pick up a EOS M deal or a used rebel. Though I doubt you will.

Agree with 99% of what you said, other than the EOS M part.  Frankly I'd like a new rebel for the price of a used one...and this might be the time of year to get lucky!!

The M is actually not a bad little gizmo once you find a use for it!! I use it to capture those "quick snaps" that would otherwise be lost while changing lenses. It means I can park a 135L on my camera all day and not worry about any wide stuff. M got me covered!

Lenses / Re: IS Versions of the 50mm, 85mm & 135mm Coming? [CR1]
« on: November 27, 2013, 09:39:01 PM »
If there is a 135mm f/1.8 IS...

Shut up and take my money canon.

I was just looking at the Olympus 150F2, it's pretty much the same thing (and not cheap).

How much would you pay for a 135f1.8? I mean, if something like that did come out it very well could end up costing $3,000.

You can get away with that if you go all Zeiss Otus on a focal length that has never had an all-around spectacular lens (like 50mm primes!).

But very few folks would pay that much when the current 135mm F/2L is so damn good and so cheap at around $900-$1000.  Folks won't pay +$2k for IS and a 1/3 of a stop faster if the resolution is the same as the old 135mm F/2L.

- A

If all they did to the 135L was to add IS, no way would I pay an additional $1K+ for that. I can understand the cost going up some, but I can't believe that the IS system would cost that much additional. $1400 or so at introduction? Maybe. Prices would probably come down to $1200-1300 after a year or two which is decent. If they tweaked the optics a bit and improved them somehow, maybe a touch higher for introduction. Honestly, while f/1.8 would be great, I'm not sure I'd need a 1/3 of a stop. If I was limited to ISO 800, sure, but with pretty good 3200 and often acceptable 6400, 1/3 of a stop is a bit less important IMHO.

Sony A99 IS system + Zeiss 135mm F/1.8 combo exists already. I would pay the premium because A lens like that is meant to be expensive, Just like the 85LII. I would rather buy a 135mm F/1.8 IS than a 70-200L II for my uses.

+1 RLP that's it exactly!! The current 135L is a freakin bargain! Look at the 35L it's priced at over $1300 maybe more and it has no IS or weather sealing yet it sells like hot cakes. If Canon put IS in a 135 and increased the aperture to 1.8 tell my why you sceptics think it wouldn't be worth $2k easy? Is the 135mm focal length special and must remain under a grand?? I think we have been spoiled by the price of this wonderful lens! The 85LII and just about every other L prime costs way more and people pay it without complaint!

1. Metering sensor and processing technology that takes in a scene, determines likely subjects and desired photo style, and gets exposure perfect 99% of the time.  True evaluative metering.

2. Switchable optical and electronic viewfinder modes.

3. 50 MP output becomes the norm.

4. Removable media becomes optional as cameras have ample internal storage and transfers are accomplished via wireless.

Sandisk and Lexar might just beat you up if you keep talkin like that (no.4).

EOS Bodies / Re: This is the Way a White Camera Should be Done
« on: November 26, 2013, 10:24:43 AM »
I like it! This would make a very neat little FF mirrorless digital camera if it were at all possible! Not into the whole retro thing but it would be lot nicer looking than the Nikon df I bet.

I was thinking it's a bit too red but if it had a small touchscreen LCD at the back it would be damn near perfect looking!

EOS Bodies - For Stills / Re: Any reason to choose a 7D over a 70D?
« on: November 26, 2013, 01:47:51 AM »
Here's a very handy noise comparison chart from The Digital Picture:
http://www.the-digital-picture.com/Comparisons/Canon-EOS-70D-ISO-Noise.aspx



Thanks for that link PWP.  It's interesting to see how little progress has been made in crop sensor performance since the T2i came out.  It confirms my own comparison between my T2i and my 7D.  Judging from my photos, they seem to have the same sensor.  And judging from the information at the link you posted, the 70D is extremely similar.  I'm very glad I have a 5D3. :)


the 7d DOES NOT have the same sensor as the t2i. The 70d's image quality is at least as good as the t2i, and outclasses both in iso performance.

As the reigning pixel peeper supreme, the t2i's sensor is superior. the 7d has severe iso issues. I guess my eyes are better :)

For the record, soooooo many people post their cleaned up, shrunken images to show how good thier shots are. For my uses, which is design down to the pixel, those kinds of examples are useless.

post 100% screen shots of those unprocessed raw files. Then u will see which is better.


For the record? Really?  ::)


How do you know for certain that the 7D and T2i don't have the same sensor? It is likely to have a sensor with very similar technology but the way the images are processed is different. The 7D has two Digic 4 processors vs one in the T2i. The AA filter is also different in the 7D. When comparing image quality between the two cameras it is very hard to tell them apart. What I found from my experience using both cameras is that the 7D has a stronger AA filter than the T2i which results in slightly softer images at similar settings (never bothered me as I shoot RAW and sharpen in post, it could be that Canon felt rebel owners were less likely to post process so gave the images a more sharpened look?) However I feel like the 7D had better colors, lower noise at high ISOs and maybe (though it could just be me) slightly more dynamic range.
It could also just be that when I moved up to the 7D I was using better glass and had improved my own technique thus resulting in better quality images?


I still have my T2i, might dig it out for comparison.

I think there will be a really big advancement in image stabilization, allowing photographers to take pictures at incredibly long shutter speeds. Goodbye tripod for most people.

I think for action and sports shooters there will be a way to capture not only a burst but a video of a few seconds from which the camera will automatically select the sharpest images and process them and "deliver" 10 or 12 good shots. No more "machine gun mode". It'll be silent and lightning fast.

Voice activated remote shooting. Like Siri on steroids. Tell it to change modes, settings etc. goodbye IR remote. I also think a voice activated app via smartphone would be good.

Intelligent dof mode. It detects the depth of the object and offers a suitable aperture as well as critical focus assistance. Like A-dep but actually works! Option to overide it for creative effect.

Point and shoot replaced by cellphones (which is already happening).

And speedlites with variable color temp built in!!  ;D

Ps could this be the same we that are likely to loose against Australia because the pressure of winning the ashes has sent one of our players home with a "stress related illness"? ::)
I mean watching grass grow how stressful?

I thought he was just another South African again once he failed and left the team  ;D

Anyway back on topic....
The other week at work someone asked me to take a photo of their team because I'm into photography.  I was handed an iPad2 to take the shot with in a office environment. The results weren't pretty.

Do share that iPad 2 photo with us ;)

I hope they at least had Snapseed on it so you could fix it up!

Actually, once someone asked me to take a pic with their iPhone. I took a few shots handed it back but then I asked for it back, deleted the crap ones and kept the best one. I didn't want them to put a crappy pic that I took on facebook!

Canon EF Prime Lenses / Re: Canon EF 135mm f/2L USM

Here's a recent one I took with this lens @ f/2 on a trip to Kyoto.

I didn't realize what a rager this thread would become, but I love it!  I'll note for the record that I consider the "gear credit" to be a minor annoyance.  It's not something that is going to shake me up.  I wouldn't even say it makes me angry.

Tangent #1: My mother in law takes great photos with a Rebel XS, kit lens, on full auto.  Not suitable for huge hi-res prints, but beautifully framed, wonderful shots.  My cousin takes spectacular photos with a fairly cheap P&S.  She's been hired to do portraits based on the strength of her images and been greeted with confused frowns when she pulls the camera out of her purse.  She's been wanting a Canon DSLR for awhile and look out when she gets one.  The point is, gear is cool and can do awesome things, but credit the photographer too!

Tangent #2: My other hobby/passion is competitive long distance running.  Believe me, average Joe on the street doesn't understand that any more than he understands photography.  It is a world most people simply cannot understand.  Keeping this in mind, I try not to get annoyed with people who say or think my training is excessive, unhealthy, obsessive/compulsive, pointless, vain, etc.  All the same, other runners and I will gripe about it because it's a common experience among us.

Some good points there. I guess when I think about it I bought a DSLR because I wanted to take better pictures. I could have bought a point and shoot and learnt that way. Does your cousin have a website? Or flickr? I'd like to see the pictures.

Congratulations!
love to get that lens. Justification more the problem than money.
Is it a good lens for new born baby pics??? :-) if so I have three months to save....

It's a good lens if you're new born is going to be about 20 meters away from you! Crikey man, get a 50mm lens and get in close! It's a baby not a lion!

Maybe once the little un is moving about you might want a longer lens but even then I reckon a 70-200 would cover it.
He's got all the lenses he need to take pictures of the baby. He's just looking for arguments to justify the procurement ;)

Ah, I see I failed to read between the lines there! Ooops!

Buy first justify later. Then sell lens to help pay for the divorce!
