Originally posted by button Sometimes I wonder if people realize what they are giving up with a 35mm "full frame" size sensor, when compared to APS-C:
1) Less DOF at any given aperture...
2) Less reach with telephoto lenses on a per pixel basis...
3) High ISO gains negated by DOF limitations (see #1)- OK, so at ISO 6400 on a 35mm size sensor, we can now freeze motion in dimly lit rooms at f2.0. Unfortunately, everything is bokeh except for the eye of the subject. Which leads to...
4) More demands placed upon AF systems...
I think the choice is obvious, especially given the manufacturing costs- APS-C all the way. We know these things are just going to get better, so why cling to the past? Feel free to disagree.

1) Great, I can never have too much DOF control, and yes, I do like to isolate single blades of grass. I have a few pics on Flickr as we speak attempting that very thing.
2) If they stopped making lenses over 135mm I wouldn't care.
3) F/2 in APS-C is pretty damn shallow as well. But what you can do with FF that you can't do with APS-C is shoot at something like ISO 12,800 at f/5.6. Either way, I don't care, if the light is that bad I see no reason to take a photo.
4) I use a manual focus camera 70% of the time. So I think its safe to say AF speed isn't much of a concern for me.
So what is obvious for you may be the exact opposite for me. Everyone has different needs
