Hello Everyone,

I wanted to share the next installment of my Rolling in the Deep series. This time it is in Komodo Indonesia. This is a wide angle look. With a Macro version coming soon. Let me know what you think.
Enjoy

Terrific video, …thanks for posting it.

Never seen a black manta before.

Is this a sub-species, or only a melanistic individual?

Great find in any case!

Larry,

It is a Black Oceanic Manta Ray. They aren't too common, but they are around.

I read posts by people expressing regret or in some cases re-buying lenses they've sold. I don't get it. I've sold a fair bit of gear, and had no regrets...

Click to expand...

I've sold quite a bit, but I did end up missing the 50L and re-bought it. I'm glad I did, too, as I use it a lot. Sometimes you don't realize how much you missing something until it's no longer there to use.

Canon SL1 with 15-85 IS. That's all you need. This gives you great IQ for the size, good image controls, built-in flash, and a lens with an equivalent of 24-135.

Click to expand...

The EF-S 15-85 might be a bit long for landscape photography; the OP may need the 10-22 as well.

Those camera size comparisons are very misleading ... in reality there is a significant difference in the space that a 6D+24-70 f/4 & a7+24-70 f/4 occupy in the camera bag. In the space that 6D+24-70 f/4 occupies I can fit in an a7+a6000 cameras and 24-70+10-18mm lenses.

Click to expand...

I have no doubt that you can pack more lenses and camera bodies using Sony's system than the one from Canon, but this is something which is also due the particular size/configuration of your bag and how you arrange your lenses and cameras. So, this really goes beyond the scope of the comparison provided in Camerasize.com, which shows only the side-by-side differences between different camera+lens combinations and the actual gain in space is something that has to be assessed by the user considering his/her bags and means of gear transportation. Finally, unless camerasize.com got the relative dimensions of the cameras and lenses wrong, the information provided are in no way misleading - but of course this information does not garantee that the photographer will make the best judgment out of it...

The point I tried to make earlier is not that absolutely no gain in space/volume is possible by changing from FF DSLR to mirrorless FF systems (i.e. keeping the same sensor), as you say you can carry more lenses and bodies by switching from Canon to Sony. My point is that more gain in space is possible by going from a FF system, which intrinsically requires large lenses for a given f/ apperture and image quality, to an APS-C system - mirrorless vs DSLR has all in all a lesser impact on total camera+lens volume/weight than FF vs APS-C.
I am convinced that using an APS-C system with fully optimized lenses (top build and optical quality) can deliver a higher image quality in a smaller package than a FF mirorrless systems with reduced-sized lenses having a compromized design and construction.

Click to expand...

I understand what you are saying ... but I was not saying the the dimensions provided by camerasize.com are incorrect, however they are misleading in the way they display the sizes by just giving one dimensional view.
Also, I shoot with FF DSLRs (2 of them) and a 70D ... I have owned numerous APS-C DSLR cameras "with fully optimised lenses (top build quality and optical quality)" e.g. Canon 7D with 17-55 f/2.8 L IS and Nikon D7000+D7100 with 17-55 f/2.8 lens and they were all bulky ... even if you put el-chepo 50 f/1.8 lens on a crop sensored 7D or 7100 they are still much bigger than a7 FF mirrorless camera with FE 55 f/1.8 lens or a FE 35 f/2.8 lens and the FF mirrorless will deliver superior image quality in a much smaller package.

Yepp, the samyang 14mm lens is a hell of a lens for the price. Sharp and nice build. Just the barreldistortion is really strong. So don't try to make architectural pictures with it, at least no on film

Click to expand...

I guess I could try and fix it in post... but I just bought a 17-40 today for a song... I may wind up reselling it... but certainly if I keep it, the difference between 14 and 17 may be significant, but not to me.

Click to expand...

You bought it for a song because the 16-35/f4L IS has pretty much made it obsolete - especially for FF. It is now quite clearly a second rate lens when compared with its newer cousin.

Click to expand...

I'm aware, but I'm not a wide angle guy... and if you can find me a 16-35 f4L for five hundy, I'll jump all over that.

The small swing you describe is normal in zoom lens "not L". Canon 28-135mm for example is much worse than that.

Click to expand...

Thanks for putting my mine at ease. When I first got my 28mm-135mm, the 'play" of the front part of the lens can be up to 1mm, whether the lens has been extended or not.

Click to expand...

Heh. When I got my 28–135, I screwed a filter on it, and the lens promptly slammed to maximum zoom from the weight of the filter. I swapped it for another one, which did the same thing, at which point I gave up and stuck with the 24–105L kit lens, despite desperately wanting more reach than that.

I'm still waiting for Canon to release a full-frame lens that's comparable to my 17-85 range-wise and build-quality-wise (besides the 28–300L monster). I'm not holding my breath, but then again, I think the 28–135 is the oldest non-updated Canon EF lens, so....

But I digress. Yes, as previously noted, some horizontal play is common in non-L lenses.

Click to expand...

the 28mm-135mm lens will extend itself to 135mm( due to the weight of the front element group) when you let the front element points down. That is normal

Click to expand...

That is poor design, as it is very rough on the lens to violently slam to a stop like that a hundred times per day....

I have a couple of questions regarding the Reikan Focal Pro.

When callibrating on my 1Dx, is it possible to have two values programmed for a non-zoom lens? When I have callibrated my 135L with the focus limiter on 1.6 meters it gives me a AFMA of +5, but when I callibrate it on the .9 meter, it gives me a value of +3. Can I have both, and will the camera recognize which setting I have on the lens?

Second, and related. How do you put in two values for a zoom lens, say the 70-200 @70 and @200?

In advance, thanks.

neuroanatomist said:

Depends on what/how you shoot. If you're at the minimum focus distance (1:1 mag, or higher with the MP-E 65), the FF camera gives you a wider field of view and a (slightly) deeper depth of field. The FF image will also be sharper. The APS-C camera will put more pixels on target. For the same framing, you'll get more working distance and deeper DoF with the APS-C body.

For my usual macro shooting (100L and MP-E 65 + MT-24EX as well), I prefer the FF sensor.

As mentioned JP2012-279048 was filed on 2012 Dec 21, meaning that this is the priority date.
In order for US20140176782A1 to claim benefit of the Japanese Patent, it must be filed no later than
12 month after the Japanese, and indeed US20140176782A1 was filed on Dec 18 2013.
Most often Japanese "kokai" patent apps are published 18month after their priority date, which is also the reason that the US version is published now. The Japanese version of JP2012-279048 has not been published on the JPO web site as of writing, but this in similar cases often happens a week or two after the US version is published..

Keep in mind though that, that many patents never "materialize"

Today I went out with four wide-angles:
[list type=decimal]
[*]Canon EF 16-35mm f/4 IS
[*]Canon EF 16-35mm f/2.8 II
[*]Canon EF 17-40mm f/4
[*]Canon EF 24-70mm f/2.8 II

For people that like to see pictures of walls: I took a few shots with each lens at the same piece of wall. The RAW files of these pictures and some additional pictures can be found in this ZIP file:

http://markkoenen.nl/downloads/2014-06-28-4-wide-angles-RAWs.zip

You can judge on the image quality yourself. Handling of the lens is as you would expect for this type of L-lens except for one thing: in case the image stabilization is turned on, the lens makes a weird noise occasionally. Not while you're focussing, but especially during moments that you point the camera at something else.

I thought this was an error in the specific lens that I got, so I went back to the shop and tried another copy of the 16-35mm f/4 and it had the exact same noise. It annoyed me this much that I turned off the stabilization

Cheers,

Mark.

thanks for all the advice everyone. I should add that I have a pentax waterproof camera that is very nice with good light and wide angle…(F2.8). However, the tele is not so good.

What do people think about for small fill flash on a 6D? I'd rather not have my Nissin di866 with me at all times. could I buy a 270 and be happy with it?

This is largely my sentiment as well.

Apparently they're playing "football", except they get to run more than three steps before a whistle is blown and you go back to sleep.

it does seem faster, especially with the 2xiii, it was already really good with the 1.4xiii as the blogger pointed out. i have noticed an issue that was also pointed out by ephotozine (i think it was them). at 120mm and around 1/200s, there is a glitch in the os. i haven't checked to see if that's been fixed?

i use the odin system with my elinchroms

buy the strato 2 recievers for the elinchroms which are much cheaper than the odin recievers for speedlights
then assing the groups and control everything from the odin controller
another benefit is getting high speed sync out of elinchrom studio lights

Thank you Rich for a news about it.
I totally missed out that and problem with my !DX just apear.
Ill contact Canon UK to resolve problem

Speaking from a sports shooter only:

The frustrating thing about the 7D is that Canon said it was for sports shooters and...The 7D pretty much sucks at ISO 800 and higher. I would know because I tried to shoot in the trenches with it for indoor basketball and volleyball for 2 years with a 1D4 as the main camera. The 1D4 kicked it's a$$ but I needed the reach. I guess my standards were high but it was awful. Shooting to the right doesn't always work. If you're at f/2.8, or worse, f/2.2, 1/500s, and still at ISO 3200 or 6400, there's nothing you can do. You can shoot to the right or whatever you call it but the only option is to slow down your shutter speed and now you have blurry athletes. Since I pretty much always shoot indoor sports wide open or close to wide open (depending on lens f/2.2 or f/2.8 ) at 1/500s and EC +2/3EV with CWA or spot metering, this was a real pain with the 7D. It wasn't as bad with a 1D4 and not nearly as good as FF.

When you went to FF, all of the problems were solved. That's what was so great. We could blow up action shots at ISO 6400 for the universities and print them, no problem. The 7D replacement really needs an improved sensor. In the collegiate scene I rarely see any cropped cameras anymore; it's all 1D4 (cropped), 5D3, and 1Dx. In fact, I did all three each of the D1, D2, D3 NCAA Track Meets this year and it was unusual in that most shooters had either a 5D3 or 1Dx. In years past that wasn't true as I saw plenty of 50D's, 7D's, 1D4's. Oddly, not this year.

Mirrorless will really have to improve to appeal to action shooters too. The AF is so erratic and slow it's just well, plain awful. I think the concept has potential though for other things. Just not for me.

Due to all of this, I will be watching the 7D's replacement very anxiously to see how it performs. If it performs decently with a better AF system, I will buy one and use it outdoors, for sure. I still don't think (my opinion) that it's going to match FF though.

On the other hand, I agree with the frustrations FF brings, meaning now you need longer lenses and a more expensive camera. It can be quite cost prohibitive.

We all know what gear heads are, or at least the typical definition of a "gear head" but I had another thought. I've been dealing with a lot of people who are absolute in their views of "gear doesn't matter at all, in any situation" and people who feel as though they are better and had it rougher and tougher back in the film days and how all digital photographers are lazy. I was thinking "Film Heads" but I'm still thinking.

Just a "light" humor thread for a Friday afternoon.

Seems like SAR has already picked up on the Canon rumours of a new sensor.

I do not know if he was joking, but he says that:

All I can tell you know is that I heard about a 54 Full Frame Megapixel sensor from Sony (with 2460 focusing points (no joke!) and the focusing area covers 78% of the entire sensor). It was actually planed for a 2015 release but maybe Canon will make them change those plans…

Not sure if it is just very quiet in the rumour website business at the moment, and they have all agreed to throw a little spice into the mix, but it looks like Photokina could be a very interesting show to attend.

And let me guess...with all those focus points...it still back focusses and misses the target?

bretcharman said:

The attached file was taken with the 300mm f2.8 IS II USM with the 2x extender, having used the old lens (as others have said) there is a noticeable difference in quality when using extenders. In good light the 300mm with the 2x is almost as good as a 500mm f4 - this is having used both simultaneously at the Leopard sighting.

Welcome to the forum.That is a wonderful introduction. Beautiful!
I see the 300 II is a marvelous lens.

Straightshooter said:

Lens -A would be doing kind of okay on the 1D but at the same time needing quite a lot of AF adjusting on one of the 7D's and just a little on the other one ???
My first question is: why on earth do these big differences excist?

Click to expand...

Hello Straightshooter!

Did you recognize and read this article here on CR?
http://www.canonrumors.com/tech-articles/this-lens-is-soft-and-other-myths/

I think after reading it, a lot of things will becom clearer to you.
When I read it the first time, I really enjoyed it. And I read it several times, because I really like it.

After that you will understand, why AFMA exists and must be done seperately on every DSLR to achieve the best results.
And of course why mechanical adjustment will only work on one specific camera-lens combination and not with other bodies.

Enjoy reading and relaxing. It really helps.

I wonder if the 64 ISO is truly native and will result in a bit more DR as well.
The improved battery life and shooting speed, group AF, highlite metering, etc, could all prove very practical.
Video improvements will likely appeal to those who need that.

Yeah, they are admittedly gear poor compared to TDP, DXO, Roger at LR, etc.

But I love the concise, consistent format of the reviews -- specifically the resolution numbers vs. aperture vs. location in the frame. It's like reading baseball cards.

The interesting point here being that photozone was getting good AF results with the older AF on the 5DII. Which, in my mind, confirms what Viggo and others were saying about outer points, cross-type or not, being problematic with this lens on the 5DIII.

I had a pleasant surprise last weekend; 35mm Sigma 1.4 on the Mk II & Ai Servo AF - consistently excellent results with fast moving (near) subjects!!!
