Hi everyone!
I'm newly registered to GetDPI, but I've been following this thread this the Speed Booster was announced. I purchased the EF-NEX SB last week and thought I'd share some thoughts with you all. It's a long post, so I'm copying what I had shared on another forum.
Okay, so I had a few days to play with it, and here are my findings so far, as well as two samples. I no longer have a full frame DSLR, so I can't directly compare the image quality of the Speed Booster to how a lens would perform on a full frame camera. I've mainly been using the Nikon Series E 50mm 1.8, because I've missed using a 50mm full frame equivalent ever since I sold my 5D Mark II.
I've mostly been shooting wide open to get a feel for manual focusing on the NEX-6, and to finally get some full frame DOF again. A combination of focus peaking and focus magnification helps me focus as accurately (or even more) as I would using an AF camera/lens. Peaking is mostly dependable once you get a good feel for it. However, when shooting wide open at 1.8, I usually use magnification to fine tune. I find that the MF process is actually much quicker than I had expected. The EVF on the NEX-6 definitely helps when using magnification. Also, I set the AEL button to MF magnification for quick and easy access.
Wide open with the 50mm, the image center is acceptably sharp for me, though may be slightly soft for those demanding tack sharpness. Image corners are soft, though not bad at all, but I'm guessing that has more to do with the lens than the speed booster. Stopped down to 2.8, and everything, even corners, are SHARP.
Here are two samples with the 50mm 1.8 and SB. These are shot wide open using MF, so please be kind. Also, I'm not a portrait photographer by any means! Feel free to ask questions!
