Yes, of course, that is the choice that the lens designer can make. but it also would then have the effect of making the whole lens longer, maybe even to the extent that, along with the body, the ...

Not me. Didn't want to have to use adapters at all. That's like an able bodied man being happy that he'd need to use crutches to walk, but the crutches would have an optional radio on board.

I may have missed the answer to this on some other thread, but does anyone know what the function or purpose is of what appears to be a 3rd ring on "R" type lenses and adapters, as they are ...

Yes, the shorter flange distance of a thinner bodied mirrorless has some potential advantages for wide angle lenses, but, famously, not so much for "normal" focal length lenses, and none ...

While it may not be what Canon decides to do, the answer to your question is: yes , it is definitely doable optically.

I know that I am trodding over much ground upon which other posters have already traveled, but here go my thoughts. I don't care if a new Canon mirrorless camera is a few millimeters thicker than ...

No matter what I say in this thread will never find agreement with everyone who reads this. I hold no illusions that anyone will be convinced of anything I mention in my opinions: these are simply ...

Your dilemma is a common one that certainly has applied to me as well. This is how I see it. As one other poster has already noted, despite the forum memes so commonly reiterated about bokeh at ...

Very interesting. Yes, there are lots of stitching and other types of "errors" derived by the limitations of the process the photographer chose to use - mostly errors in time, causing errors in...

Yes, I definitely agree. Great lens. Can't say too many good things about it. If you need this type of focal length range in a hand-holdable lens, this one is the best you can get. I use it more ...

As to corner performance with my 70-200 f/2.8 II, I would rate it to be more than acceptable at wide apertures from f/2.8 to about f/4.5. Stopped down further, corners sharpen up about as much as...

Just yesterday, after reviewing the results of my last two shoots, I marveled at just how good the 100-400 IS version II lens is. I think that it may nearly, except in the lowest of low light...

Although I was a digital pioneer among commercial photographers, I was also someone who shot film as a professional, and color transparency film in every format from 35mm to 8" x 10", all the while...

Have both the I and II versions. There is a very small difference in recycle time (standard 4-AA battery power) and temperature rise, but it is very hard to notice unless you really shoot a lot of ...

Yes, it is the mark II. Never had the first one, but I handheld this one quite easily for such a big lens. There is one positive/negative about the lens. It is probably smaller/lighter for carry ...

I am not a nature or birding photographer, although I do pursue those things for fun on occasion. I am a very long time pro who mostly shoots people and products for big corporations. At the end ...

These were not written as 4 consecutive posts. They were written as one. But the site only allows a short number of characters in each post. Therefore.... The whole thing together explained one...

As an aside to the poster who said that it would be better for an upcoming shooter to learn software rather than lighting, I have to say, no and yes. As a true pioneer in digital imaging for...

You EARN your knowledge the hard way. And, sometimes, some shooters (like me) enjoy explaining to assistants just what they are trying to accomplish and how they intend to do it. But if they are...

In order to gain the requisite and sometimes arcane knowledge of how to properly light a car on a studio stage (or even on location), almost all current photographers have worked themselves up from...
