jankap Posted May 10, 2017 Share #1 Posted May 10, 2017 Advertisement (gone after registration) I am fixated on APS-C somehow, but with Metabones there is a way out. To ff (lower case letter!). Here is an example of the Summicron R 50mm. No CA correction, not cropped, but sharpened. F/stop@8. Welcome, dear visitor!

Advertisement Posted May 10, 2017 Posted May 10, 2017 Hi jankap, Take a look here Metabones lens booster for R. I'm sure you'll find what you were looking for!
jankap Posted May 10, 2017 Author Share #2 Posted May 10, 2017 I like wide angle lenses. So as I found an Tamron 17mm 3.5, I could not withstand. An Adaptall to Leica R adapter was on Ebay too. Here is an example: CA had to be decreased, no crop, sharpened and at f/stop @ 8. Do you see the cat? Jan Welcome, dear visitor!

jankap Posted May 10, 2017 Author Share #3 Posted May 10, 2017 (edited) Here he is! Last picture cropped from a sensor with 6000 x 4000 pixels. Not a bad lens, I would say. Jan Welcome, dear visitor!

jmahto Posted May 15, 2017 Share #4 Posted May 15, 2017 Which APS-C? Which booster? What cost? Loss of sharpness in corners? I use Nex-6 as cheap backup to M240. Would be interested in details.... Link to post Share on other sites More sharing options...
jankap Posted May 19, 2017 Author Share #5 Posted May 19, 2017 Hello jmahto I used a Sony A6500 with a Metabones ultra. My booster is for Leica R to E-mount. It costed 400 Euro. I am testing still, but look at the pictures. The booster can be fine tuned at infinity. That was necessary, so I think I have got a return copy. The screw for the tuning is extremely small. But, there are no lens booster for Leica M! The flange distance of 27,8mm is too little. R-lenses have 47mm, because they have to let pass the swinging mirror. I use a Summicron R 50mm. It was necessary to hone at the mount side the stand protection (by van Manen). Standing on the table with the mount side is forbidden now.

jankap Posted July 16, 2017 Author Share #6 Posted July 16, 2017 A few years ago a painted window in Straubing (Bavaria) was recognized as being a Dürer design. Dürer died in 1528, so it was undetected for almost 500 years. There is no proof for this, no paperwork left. But my guide - C.J. Zink - is convinced too. The first row (the clouds) are not the originals. I had my Summicron 50mm with the lens booster with me. Welcome, dear visitor!

Would be interested in details.... Hi jmahto, you seem to be a follower. My pictures run through Lightroom and Photoshop. If you are interested in originals (corners, etc.), send me a mail. The lens booster is very good, but it isn't a lightweight combination with camera and lens. Jan Link to post Share on other sites More sharing options...

Jan My issue is that I use R on APSC only for tele. For wides I do have M240. I also have Konica Hexanon set in wide to normal that I like. Unless there is a booster for M or Konica mount distance, it is of little use. I read a little about 17 tamaron. I would love to compare that against CV 15 (I use vII) which is very light and I have got some good pictures with. If Tamron plus booster is heavy combo then I am happy with CV15 on M. In any case, if you have a picture with infinity distance with Tamron 17 then please share the link in direct mail. I will be curious. 1 Link to post Share on other sites More sharing options...
jankap Posted March 3, 2018 Author Share #14 Posted March 3, 2018 The wide angle tests failed, too many parameters. I´ll repeat that. I compare the Tamron with a VC 12mm 5,6 LTM. Here is a link to an older test, the 280mm 2,8 with and without lens booster. I think, that the LB is optically very good. The test without LB is with 2 adapters LEM/LER and NEX/LEM. https://www.dropbox.com/sh/9zmzsqbd9oep5em/AAAtpPwO0hwAFXTqB5iu6v-1a?dl=0 The weight of the lens booster is 200 gr. The Tamron + adaptall + LB is 540 gr. The VC 12mm + adapter weighs 300 gr. Jan Link to post Share on other sites More sharing options...
