Excellent and interesting composition on that last one mazor. I like it.

Here are a few more from the outing with my daughter from a week or so ago. All on the 7/speedbooster/ML 28 combo.

as ken_vs_ryu said, and remember you will lose any kind of infinite focus by using this type of macro adapter.

Basically using this adapter is the same as trying to mount M glass onto a DSLR. The same limitation applies, except when used on a Speed booster adapter, you will get 1 stop extra light advantage.

so the solution is...

the leica m macro adapter for nikon and the nikon version of speed booster , so i can mount my noktons (m mount) in sony nex ?

what is the disadvantage here ?

The disadvantage is you can only do macro (closeup) shots.
You won't even get close to infinity focus.

Captured with my NEX 5r and Speed booster and Canon 50mm f1.2L attached



In was so dark inside. I believe no camera with kit lens would have been able to capture this with such clarity without external illumination.

f0.9 rocks!!! Speedbooster is the best invention for APS-C Sony cameras!!

Recently I acquired a Metabones speedbooster for my Olympus OM lenses.

Today I took it for a spin with my Zuiko 24/2.8 and can say I'm very happy with the performance. I tested some of the same scenes vs. my Minolta MC 17/4 and both center as well as corner sharpness is better. Even comparing wide open it still shows better center sharpness and contrast, so that's comparing f2.0 with the speedbooster to f4.0 of the Minolta lens. So I'm a happy camper, and the MC 17 will probably see little use until I get a FF E-mount camera.

1: Water lilies and reflection


2: Yellow meadow


3: Fishing pond


All at f5.6 setting on the lens, which makes it f4.0 with the speed booster.

How many SB users have checked infinity focus at larger apertures? I have four Metabones boosters and all of them required a good deal of adjustment to get right.

Mine too, I needed about 3/4 of a turn to get it right. But after adjustment it's perfect
