Canon should be able to fix it. They will probably have to replace the assembly.

Finally plastic mount has found its way from cheapo kit-zooms into cheapo cameroid-bodies. Peephole viewfinder with record-setting 0.57x mag displays the occasional photons not swallowed by fixed mirror in lightpath. LCD with 400k subpixels displays subject scene. Commodore C64 revisited. Yikes!!!

On my visit in Zeiss factory in Oberkochen, I had very short opportunity to play with new Otus. Not exactly fine art photography here :, just fast snaps to see how it can perform at infinity and WO performance/ bokeh.



This thing is crazy sharp and contrasty WO as expected, only very small traces of LoCA WO and no traces of LaCA at all.
This particular copy looks slightly decentered at left side, but with good copy, you can probably shoot perfect infinity landscapes WO....nightscapers wet dream come true

Here you can download the RAWs.

And a side note, there is plenty of half-cut lenses over the entire factory...I wonder, if they have special department for this

As others have mentioned, the 5D3 is not UHS compatible for SD. That means it cannot write at the speeds at which faster SD cards can accept these days. It uses an older standard.

Therefore, the SD slot is considerably slower than the CF slot (even if you have identical speed CF and SD cards).

For this reason, write speed is capped to the slower slot. It's 1 image at a time. Until all slots are finished writing that one image floating in memory, it can't clear it from the memory buffer.

When there is only a CF card present, the camera does not have to slow down for anything and writes at the maximum possible speed. Which is the maximum speed of the CF card.

Thus, the full-speed continuous buffer is smaller the moment you insert an SD card. Because the camera knows it can only buffer so many images and write so many simultaneously before it slows down based on the slowest slot - which is the SD slot.

It's a hardware issue, and will never be resolved.

Canon included faster SD on the 7D2 and 5DS.

You are quite welcome, Hector.

I absolutely positively love these - great job!

Hey...i got to know every thing about Olympus OM-D E-M10 Mark II from the above review but i think something is missing there. Well if you just want to make sure you can follow the link below because here from the link i came to know complete information regarding the camera from its good points to the bad one.
http://www.gizmobeat.info/olympus-om-d-e-m10-mark-ii-review

A comprehensive summary on what FF mirrorless could be. Not a Canon rumor so much as a rollup of one photographer's experience shooting next to everything on the market today (the opening police lineup of mirrorless rigs is a great conversation starter):

http://blog.mingthein.com/2015/11/03/how-to-design-mirrorless-right/

It's full of opinions, priorities and wants that are likely not the same as yours, it's still pretty damn insightful. You'll find your head bobbing in agreement to a number of his comments.

(Had no idea Nikon had an auto ISO setting that could be set to a shutter speed of 1 / [Lens FL]. Canon, please add that to my 5D4 wishlist along with spot metering at any AF point, thx.)

Take a look at this:

Bought it myself and it is very good!

I have started to read it. Lots of good information. Now to find the sections I need for landscape photography using Canon lens attached via a Metabones adapter.

Landscapes, that's the easy part.

1) map a custom button to toggle MF on
2) map a custom button to focus magnify
3) find a landscape



I go back and forth on whether I want the display based on exposure settings. For very long exposures in low light it gets crazy bad with a ton of gain. In those situations, the rear display beats the EVF. For pretty much everything else, the EVF is better.

Well, he beat out Starbucks and Annheiser-Busch, but I noticed that Volkswagen came in at 20 and even Jeff Bezos made it in the top 100, despite abusing his employees.

Why is Canon faster than the competition?

Simple - they produce the 1DX!
Tried the opposition and I was not that impressed, unfortunately the owners of the "opposition" were using my 1DX while I tried they gear - they were quite unhappy. Pity as they are good photographers and friends so I felt for them. I won't get into long lenses as they were even more unhappy here.
P.S. On my last visit to the Alps the cyclists were MUCH faster downhill than I dared go - they are nutters!

I tried to resist the urge to buy this but ended up pulling the trigger, and all I can say is WOW so far. The build quality is amazing, better than any lens I own. It's a bit deceptively heavy due to the metal, but it feels very balanced on my 6D. Seems extremely sharp, even wide open (not sure about the edges, but really, how often do you shoot at 1.8 and need tack sharp edges?). It's also the first lens I've ever bought that focused dead on without any microadjustment. The thing I really noticed though is that 45mm seems like a great focal length for street photography - I've kind of been on the fence about whether 35 or 50 is better for that, and I've mainly stuck with the 35 F2 IS because the IS is so useful for night shooting. 45mm seems slightly more general purpose than 50mm, and I think it's gonna be the perfect compliment to my 16-35mm F4 IS in my travel kit.

The 2 downsides I noticed are the same ones everybody has pointed out - 1) chromatic aberration is a bit high, esp at 1.8. Should be correctable once DXO/Lightroom release plugins, but it is an issue. 2) AF speed is definitely on the slow side. If I had to pick between accuracy and speed, I'd choose accuracy, but it's definitely noticeably slower than my 35mm F2 IS.

Overall the lens is amazing, it's what I've been waiting for as far as a great general purpose normal prime (wake up, Canon). With a fast normal image stabilized zoom, I think I can finally sell my 24-70 VC, since there are few remaining situations I can imagine wanting to carry it around.

Let's also not forget that the Queen is German (from the House of Hanover). The royal family took the surname "Windsor" to sound more acceptable to the British. Mind you, go back far enough and we're all African, so who cares?

Re: Canon EF 11-24mm f/4L & EOS M3 Honored with Design for Asia Awards

The M3 is hardly an award winning camera, whilst a worthwhile improvement over the previous models, it's not outstanding.

FF please, or don't bother at all, Canon.

Do you really believe that a company, which never cared to make any competitive EF-S primes (for 15 years now), will make your dreams come true? Well, I hope so . In fact, their crippled and overpriced M bodies will keep the DSLR system safe (from progress), kinda ;D.

I expected a better coma performance since well.....its meant for astro, but still its tempting at 20mm and $1k, though the 35mm f/1.4 II tempts me more, waiting for lenstip's review of it, but even if it's not better, it will get higher usage.

Is it possible to use Surface Pro + LR and PS without the keyboard? How is Ctrl, Alt and Shift + pen handled without keyboard? I'm using Wacom Intuos Pro with desktop PC and it still have few buttons on the tablet mapped to these keys.

Maybe the lens craze is subsiding when people start noticing that nobody interesting really is interested in what kind of lense was used to take the picture of the computer keyboards of the duck in the local park or the round-eyed toddler of the family...

Eventually, his growing family will grow into adults. What will he do then? Maybe adopt some young kids

His kids might grow into adults but Ken himself...not likely!

Some lenses are designed to let you change the mount. Zeiss CP lenses are set up to do that, and some high end Canon cinema lenses (North of $40K). I doubt if Sony lets you change to a EF mount.

If its a savings to you, you might get a different lens and sell the Sony.

http://blog.abelcine.com/2013/11/13/changing-zeiss-cp-2-lenses-from-ef-to-pl-mount/

There are pl to ef adapters for a limited number of lenses. Some buyers indicate that the adapter worked on their Sony pl mount lens, but I expect that not all will work.

This is from one of the comments on the B&H web site:

"It should work with any PL lens, but I can say from personal experience that it works with my RED 50-150 zoom, RED 300 prime, and Sony PL primes, Zeiss PL zooms, and many others.

You lose 2/3 of light when it hits the CFA before getting to the sensor. Wow, that's a lot...

What they dont say is how much computational work is required to calculate the colours, but I'm sure they will be reaching out to Sony to see if they want to license the tech...

Thanks for sharing...

Click to expand...

This is a major reason I hope mirrorless cameras quickly acquire a 3-sensor design: no filtering. Losses should be much less through a trichroic prism than through a CFA.

I've seen a few comparisons done between these bodies but for those of you who prefer the inconsistencies of real-world comparison shooting to lab data here's a bonanza of studio and outdoor test shots using some of the best glass available. (in progress)

I did and at first all was alright, however after some hours it started again, check the attached photos which were taken at the same time.

I SEE U DONT KNOW WHAT YOUR TALKING ABOUT SMH
you were at the photoplus expo too say what needed too be done

tomscott said:

so u saying the 7D mark too isnt that good at high end portraits?? hmm

well i guess this isnt high end portraits

Click to expand...

I didn't say it wasn't suitable, I said it would save people money unless they are looking for a high end portraiture, specific look.

In your images above I would say a FF camera would have been more suitable as there is a lot of DOF to the point where the bg is distracting in both images, especially in the first image with the black curtain not sure whats in the bottom right corner but at a wider aperture would have looked much more aesthetic.

At F5 your effectively shooting the equivalent of F8 at 85mm against a flat background with a lot of texture, close range not leaving much room for a clean background. If it had been shot full frame you could have got a nicer creamier background but at the distance the subject is to the curtain it may not have made much difference unless you shot a much larger aperture. It would have also added a better bokeh effect in the second, but again he's so close to the lights it would be difficult. Changing the perspective moving the model further forward would have given a creamier look. But depends on your intended look.

But if your shooting in a studio with controlled lighting a FF camera is a no brainer.

DXO needs to get a tester like the one Lens Rentals has. Then they also should test coma and some of the other attributes.

Astigmatism, coma, etc. But, coming up with a value for sharpness is difficult. Most testers give a value for the center, but measuring falloff of sharpness towards the edge and giving it a value that means anything is impossible. Some testers have tried to average it, but that's no good, so showing the colored graph seems to be a good way for depicting the performance of the lens from edge to edge.

I'm not a fan of testing lenses on a camera simply because so many other variables come into play. There is no such thing as a perfectly aligned camera, the mount is always off, the angle of light striking photo sites is different from camera to camera, the accuracy of the sensor alignment varies by individual camera, I've read that the built-in correction for light fall off at the outer pixels is done according to a internal data table for each lens in the camera firmware, there are just too many variables. Comparing from brand to brand is even worse.
