The A77 thread (cont'd)

If you want to use a slow shutter speed and don't have the necessary ND filters, it can be useful.. however if you lose dynamic range it is less useful.

A couple of things we can learn from the picture that we didn't know - the camera has raised numerals on the mode dial like the a900 (but unlike the a850) and the body finish appears to be the dark matte of the a850, rather than the satiny a700/a900 finish.

Again, fodder for some other thread. Who says that. No reason to believe a bigger body does not use the iISO hot shoe. Esp if it comes with build in EVF (that isn't even available for the NEX 3/5 port).

Who says what? What exactly is your question? What exactly is your point?

looks like the same mode dial on the 580 actually.

People don't care about ISO 50 or if it was ISO 45 or 55, the point is many folks want lower ISOs. Film had very low ISOs, options. This is important if you want to take longer photos.   I honestly think the number of folks who want low ISOs is similar to those who want pointlessly high ISOs, so why shift one way.

Sensors just have one sensitivity, it's base. Everything from there on is boosted with circuitry (power). A sensor will always perform it's best at the lowest possible ISO.    Shifting things up just becomes a pain to folks who use those low ISOs. People don't want to have to put ND filters on their lenses. Just like any other filter, people want to avoid filters, it's a pain and it's cost. Also if a person was putting ND filters on at ISO25, and now they only have ISO200 as the base, they have to add more filter to make up for that just to get to where they were.

It's good to here they both have GPS, if Sony blew that one after the success of the A55, that would have been dumbfounding. In interviews reps had said GPS will come on the higher end models in the future, so it's good to see it stays.

Lets just hope this holds for "NEX-Pro"

I agree, such camera should have it's own thread, but it is semi-relevant as it probably shares many the features of an A77.   Folks should probably look at lots of things as "how does this work for both systems" as they will probably share more than not. So how something might work in an SLT body may be helped/narrowed down by considering how it would work in a NEX body as they would probably want things commonly implemented.

I dislike Jazz.

Not much of a fatboy slim person, though it's ok. But I have always liked that scene (girl before is ok too).

Also as an engineer, I always tend to think of engineers from the 70s always looking like that (the dudes with fro's)
