So basically, you're pointing to information over a long period from the same source in relation to the 5DmkIII and compare that to A) a camera that isn't too relevant here because it's not part...

All DSLR's (and SLR's for that matter) have a partially (in the center) semi-transparent main (flipping) mirror, to pass light to the secondary mirror underneath, which in turn bounces that light...

The 135mm is probably not going to be a good example to showcase its AF capabilities to begin with, because it has the old screw drive AF. It's in need of an update (and rumored to get one) in this...

"Who cares about the outdated stuff anyway :)."

Apparently you do, because for example that Sigma 150mm on your owners list, is still produced for the A mount too.

I'm not sure why we would compare different cameras from different makers to conclude anything about the effect of a Sony beamsplitter.

Here's a better comparison, SLT's left, non SLT's using the...

" and your saying it's faster?"

Reading comprehension test failed. I never said such a thing, I said it's not really slower for the same type of use.

Again, you have the choice to use a higher...

That's a bit of a fallacy, because no one suggested that shutters can't introduce vibration either. Both moving mirrors and shutters do. But a camera like the A7RII for example, can get rid of...

Between both of them, they still make 55 lenses for the A mount.

I didn't say that high ISO should not be judged under daylight lighting, since that's where many sports shooters still hit high ISO too. I said that if you want to compare low light high ISO...

"plus it's not relevant."

It's relevant if you suggest that the camera is made significantly slower, which is what you did. The fact is that it's not, for the same type of use.

You may soon be...

"The guy has more photographic knowledge in his little finger than most of do in our entire bodies."

Which is highlighted by the fact that after decades of being a photographer, he still wasn't...

It's so quiet now. What's next: only this week, next week it's gone, these short interval Amazon "statistics" need to be monitored over a longer period to be telling!

Yeah, which begs the question...

@ HFML:
"isn't the 12fps only available in a mode, freezing the AF at the first frame?"

No, it allows AF+AE with 12fps, as demonstrated with examples during the presentation.

It's positioned under a 60 degree angle, but the results are similar.

No, the mirror is larger than a moving one and extends beyond the mount/throat when flipped up for cleaning. In part because of the different angle and in part because it requires a surrounding...

30% on the log2 scale equates to 0.5 EV. Looking at Dxomark measurements between Sony cameras with and without the beamsplitter while employing the exact same sensor, we see differences ranging...

No antivirus software running, only when I activate it for a weekly scan and dealing with fragmentation is part of keeping the "trash" out. A dedicated partition for the page file and regular ...

My 10 year old XP machine must have missed this piece of information. It's no slower than when first bought, even during its second life as a machine for the kids. Just a matter of keeping the ...

Having more direct controls (including that joystick for AF selection and quick navigation, also the silent control ring at the front and top LCD) is part of better ergonomics, as is the more...

This is where the flicker reduction should help too (exposure for peak brightness during light cycle).
