@Vitaliy_Kiselev Any estimate when Lens Turbo II will be in PV deals?

Hello, I bought last year a RJ focal reducer II, FD to m43 (100 euros), which I enjoyed with my GH2 and my FDs lenses. But there was this blue dot problem that annoyed me, and also the fact that the focal reducer had some play, making the lens moving when focusing or changing the aperture. Just two days ago, I received my ZY Optics/Mitakon focal reducer (FD to m43, 150 euros). I was a little afraid about that blue dot issue coz I couldn't find any review that confirmed that the problem was solved. Now I own it and tried it, I can say this ZY optics focal reducer is just perfect : no more blue dot issue, no more play between the camera and the lens, and moreover I have the feeling that the sharpness has improved compared to the RJ focal reducer. So now I'm (fully) happy ! :) Now I'm looking for declicking the aperture of my FD lenses... DIY way or in a shop in Paris where I live... Hope my review will help!

PS: one cool thing that imo helped to resolve the fact that there was some "play" between the camera and the lens, is that there is no more the "lock/open" wheel on the focal reducer. You just put your lens on it, and that's it. But I have not tried it with "old" SSC Canon FDs breechlock, only with newFDs.

Really hope that ZY Optics optical quality would be acceptable and the MD version would be compatible with Minolta 35-70 zoom. Would be fun parfocal lens to my collection.

New MFT turbo adaptor features a structure of 4 lens elements in 4 groups, including 1 extra-low dispersion element which helps in reduce the chromatic aberrations on the image. The angle of view of the camera lenses will be increased by 0.762x and the max. aperture will be improved by 1-stop.

Version II of the lens turbo adapter has a completely different optical design from version 1 and a much-improved coating. The optical performance has been improved a lot too.

Will be available on deals here on November 2015, suggested retail price of $149, deals one will be lower.

You have to try it and find out, Im not sure.

Not sure about the Mitakon, but the RJ has a screw that you can loosen to then manually turn the inner glass to raise/lower it to adjust this.

Dear Vitaliy,

is there a Lens Turbo II for Minolta MD/MC?

TIA

What is the best Metabones clone for Nikon G to Sony E mount?

Is it the Mitakon Lens Turbo II?

Or would the much cheaper jinfinance be just as good?

Hey guys I recently picked up the Mitakon Speed Booster. I only plan to use this in lowlight situations with the lens wide open so no other uses besides that. Most of the glass that I have are the older D series lenses with the aperture rings so this adapter works out perfect for me. I plan to use this with my Tokina 28-70mm F/2.6, Samyang 35mm F/1.4 and my 80-200 F/2.8. I performed a basic test on my Nikkor 70-210 F/4 @F/4 just to see if I would notice the degradation in quality. Here is a link for the test that I performed let me know what you think...

Enjoy ;-)

Sorry, I am totally out of the Mitakon discussion. For MFT only the Nikon Ai-S exists so far? MD?FD?

MItakon is a lot sharper in the center, I prefer center sharpness anyday, thanks a lot for the comparison, I would love to see some video comparison can you please do that for the comunity @jobless THANKS AGAIN

@jobless Thank you for this test.
