EOS Bodies / Re: Using full frame lens on crop body cameras ?
« on: December 16, 2014, 06:39:09 AM »

The only elements that would be smaller are the small elements nearest the camera. The largest grouping would be the same. on lenses longer than 50 or 60 mm it makes a hardly recognizable difference.

Telephoto yes, wide angle no. Just look at EF 24 2.8 and EF-s 24 2.8. The EF-s one is actually a 38 equivalent FoV one so it's narrower and a lot smaller.

Using a 70-200 on crop would be less wasteful than using a 16-35

When you mount the same FF lens to a APS-C 1.6x crop sensor, you are essentially only capturing 39% of the light (photons) the lens collects, and throws away the rest of the 61%. No matter how you spin, that is a loss.

So yes, using FF lens on APS-C is wasteful, because you could as well use a native APS-C lens with the same focal length and aperture, and it will be a lot smaller and lighter because the glass in it collects light from a narrower angle of view so it doesn't have to be as large.

Center weighted because I don't want the AF point to influence my choice of exposure. I will always dial in +/- EC before the exposure, judged by the zone distribution of the scene I want to photograph. So no right choice for my in the topic since I am not trying to be "lucky" but try to dial in the actual exposure.

Take the 5D3, put 7D2's 65-pt all cross focus system, 150k meter (this one is optional), 36MP Exmor sensor and you can shut up and take my money!

Yes, it's caused by the mirror box geometry blocking light rays exiting the rear element (essentially forming a rectangle aperture). Just something you have to live with by getting a f1.2 lens on an SLR type camera.

You can reduce the effect by stopping down, and moving the background lights further away the subject.

Does it have 4K recording?
How many stops of usable sensor DR?

Please at least let us see a glimpse of hope that you will up in the sensor game? If it's the same 11-bit sensor they can go to hell.

Why us mere mortals have to care about this?!

And does it increase the DR of their cine cameras? BOOOOO!!!!!! ::) ::)

It's the same 11-bit DR sensor, nothing to see here, move along.

EOS Bodies / Re: EOS 6D Mark II to Move Upmarket? [CR1]

I think people need to take their brand-glasses off if they can't see how the 6D was intentionally crippled.

Exactly, if they didn't put the old ass 1 cross point AF in 6D, the sales wouldn't be so bad. Even the AF from 600D where you can rely on a outer cross point is far better.

Canon should learn from Nikon in this aspect. Put the 61-pt AF on next 6D and 65-pt all cross AF on next 5D, you will sell more and there is nothing to cannibalize.

If next round of FF from Canon still has the lame 11-bit DR sensors and 11-pt AF for entry models, consider me a goner. My faith in Canon is at 15% now.

No new sensor == no sale for me.

I'm gonna hang on to my old trusty 1Ds2 and 1Ds3 pair until Canon comes out with a true next gen sensor, or till my patience run out and dump em all.

Wow, if the dude in the video was a foot taller, he'd look like a clone of one of my photography instructors.

If he was 10 times smarter he would be Einstein.  ???
