If Sony removes direct buttons. We have another case of removing features, this would be bad as I don't consider it an upgrade. I use the WB direct button often along with ISO. Hopefully Sony has learned a few things in the previous product cycle. I'm really hoping the A-7XX retains all that was great about the original and adds all that the competition has added over the years.
Yep, the 7xx will be a sign saying it's coming someday, while the NEX 7 will be promoted like mad with piles of them all over the place.
Yep, that's right, no a7xx. Only beginner cams.
The expectation would be that the main ad point for Sony is going to be high FPS, probably 15FPS or higher, with the AF getting more light it should be able to keep up. They have been test surveying various ad slogans all of which are along that line. Machine gun your shots and pick the best from a pile of video frames seems to be their emphasis.
The EVF shouldn't require any light to be diverted from the image sensor -- the concept drawings indicated that the EVF feed would be coming from the image sensor itself. But yes, the mirror will have to divert some of the incoming light away from the image sensor, and toward the AF module. My guess is that the diverted light will amount to approximately .5 to .7 of a stop.
When you say "like a normal DSLR", I assume you mean using phase-detection AF with the mirror down, and then flipping the mirror up for the actual exposure. That would be nice. Or yet another alternative mode that has been discussed as a possibility, would be for it to flip the mirror up and keep it up during and between shots, while allowing manual focus and/or contrast detect AF -- thus mimicking the live view mode of competing DSLR brands, or the main sensor LV mode of the current A500/A550.
That is my feeling on this. We know nothing about the a7xx, not even if it will arrive.Too soon to get overly excited, but a little bit is okay.These are still just rumors, right? Is there a link to a Sony announcement? We'll know by the end of August if this rumor is true. Then when we see the actual cameras we will find out whether Sony botched it again by leaving out important stuff, poor implementation, bugs, etc. Remember, we are talking about Sony here. Anyway, I have my fingers crossed.
Look at how many different 32", 40" etc. TVs they produce. It's called "choice".
Is that why there's always three variants of Nikon's top models? Even the D300 has a variant with one added feature. Is that because Nikon HQ have no clue?
Walt, you're more familiar with the "old" pellicle designs than I am. I really like the overall concept of Sony's proposed design, utlizing a less fragile mirror of more-or-less conventional thickness (in DSLR reflex mirror terms, anyway). But there's one thing about the design that worries me ...
EOS 1NRS reduced the light by 1/3 for both AF module and OVF, which is about 0.6 stop loss.
I assume you're talking about the D300S here. That's not a "variant" -- it's a replacement. A minor upgrade of the D300, to be sure, but an upgrade nonetheless. And most importantly, not being manufactured and sold simultaneously with the D300, as a "variant" would be.
Could be. But then again, the specs for the current Canon 1-series pro DSLRs show that the semi-transparent main reflex mirror passes 37% of the light through to the secondary mirror that reflects the image to the AF module, with the remaining 63% being reflected directly up toward the OVF. Specs for the lesser models are similar, but with the split being 40/60 instead of 37/63.
Same here -- although I normally have little faith in rumors as a general thing, anyway. But I sure can't think of a valid reason why the coverage of an EVF being fed directly from the image sensor would ever be anything other than 100%.

Same here. We keep hearing how EVFs will "soon" be as good as an OVF, but the most recent one I looked at, the Panasonic GH-1, was no where even near as good as an OVF. I hope these new Sony EVF cameras (if they even exist, it is just a rumor) are at least better than the one in the GH-1.
The A700 still has the firmware sleep mode bug when eyestart is off that was reported years ago. The A700 has the control wheel problem that has hit quite a few people that is probably either bad design, bad QC, or just a batch of bad parts that got in some.
Has there ever been, a month before the announcement of the four cameras?
