Re: APSC vs FF

Let's be practical. I agree FF is better. Yet I have spent a lot of money on the NEX-7 and a bunch of E-mount lenses. I also have Metabones Speed Reducer. When I am in low light, the SB plus a Canon FDn 50 1.4, does an excellent job with only having to go over ISO 800 very seldom.

The bottom line in the real world is how much would I actually gain in picture taking by scraping (actually selling) all my APS-C equipment and starting over in FF. While FF is theoretically better I'm not sure the cost is worth it. I print up to 16x24 and would be hard pressed to imagine much improvement in the actual images. And I am picky.


If you only have one legacy full frame lens, and you're happy enough with the IQ of the Speed Booster, then it sounds like you've found the right solution for you.

I didn't try a Speed Booster. Metabones took so long to get the FD one to market that I instead had to try one of the other brands. I was very disappointed in its IQ and I returned it. By that time, the A7 was announced. I shoot a number of different brands of full frame lenses, so A) the cost from Metabones for multiple adapters would be higher than the cost of the A7 and B) a number of them aren't supported (or even - Leica, Contax G, etc) supportable by focal reducers.

I have heard, though, that even the Speed Boosters work better with some focal length and speed lenses than others. A real full frame sensor works well for all of those SLR lenses.
