andy lee Posted May 9, 2014 Share Posted May 9, 2014 yes just use it as a dumb Canon mount so your m42/ Pentax/ Olympus/ Contax Yashica etc mounting rings work fine on it it turns your 2x crop Panasonic into an APSC Canon - ish ! Quote Link to comment Share on other sites More sharing options...
OzNimbus Posted May 9, 2014 Share Posted May 9, 2014 So my RJ M42toM4/3 adaptor arrived 30mins ago & all seems fine. Slapped a few lenses on it - a couple of Super Taks (35 + 55) & a couple of Russains (Mir-24M + Helios 44-2). Well as expected they get a lot wider & faster now on the BM Pocket. Sharpness wideopen does have some roll off towards the edges, but this could be due to the lenses. Stopped down a little & they do appear to be tack sharp. No blue spot so far... For the price all is good. Sounds interesting... where can I order one? I've got a ton of M42 glass I'd love to try out! Quote Link to comment Share on other sites More sharing options...
dishe Posted May 9, 2014 Share Posted May 9, 2014 Will it work ok if I use my vintage Lenses adapted to EF then on the Ef - M43 Reducer? You know 2 adapters? Should be fine shouldn't it? Save me buying an m42 reducer when all my older lenses have been adapted to EF anyway. I am currently using a Nikon to EF adapter on my RJ EOS-to-M43. No problem at all. You have to make sure the adapter you are using is high quality though. One of my Nikon-EF adapters is a cheap one that has some give to it. On its own, it was good enough to use on a Canon body, but on another adapter, that give gets a little more exaggerated. You want the lenses to be tight. Sounds interesting... where can I order one? I've got a ton of M42 glass I'd love to try out! I'd buy from the source to make sure you are getting the most recent batch. http://www.rjcamera.com/ocart/ I got mine from there.

dhessel Posted May 9, 2014 Share Posted May 9, 2014 I just got a RJ MFT to M42 reducer and I cannot even get it to seat in the lens mount on my BMCC. It almost seems like the adapter mount is a little to large in diameter. Any ideas? Quote Link to comment Share on other sites More sharing options...
Bioskop.Inc Posted May 10, 2014 Share Posted May 10, 2014 Sounds interesting... where can I order one? I've got a ton of M42 glass I'd love to try out! Got mine through his Ebay store: http://stores.ebay.com/rjcameraaccessorystore/ @ dhessel - sounds like you're going to be needing a dremel to adjust it yourself!

Lucian Posted May 15, 2014 Share Posted May 15, 2014 Got mine through his Ebay store: http://stores.ebay.com/rjcameraaccessorystore/ @ dhessel - sounds like you're going to be needing a dremel to adjust it yourself! I ordered one and it arrived quite quickly. I have to wait for m43 mount for my digital bolex next month, but looking forward to it. Quote Link to comment Share on other sites More sharing options...
cantsin Posted May 17, 2014 Share Posted May 17, 2014 I just got a RJ MFT to M42 reducer and I cannot even get it to seat in the lens mount on my BMCC. It almost seems like the adapter mount is a little to large in diameter. Any ideas? I do have exactly the same problem as you. Quote Link to comment Share on other sites More sharing options...
IronFilm Posted December 3, 2014 Share Posted December 3, 2014 I've send them a suggestion for a medium format focal reducer, I have totally failed to do one on my own (it has terrible aberrations, and only 0.6x reduction), I want to use my glass digitally without spending millions on MFDB I have a Pentax 645 to Nikon F adapter, so then I can put my medium format glass on a speed booster :-) Only get a 0.71x of course, but is something! And waaaay cheaper than buying a Pentax 645Z! (though I'd love to own one) Quote Link to comment Share on other sites More sharing options...
IronFilm Posted December 3, 2014 Share Posted December 3, 2014 Am I correct in assuming the "jinfinance" seller on eBay and the rjcamera.com website are exactly one and the same person? Thus if I purchased either of these two products I'd get exactly the same item: http://www.rjcamera.com/ocart/index.php?route=product%2Fproduct&path=20_65_66&product_id=62 http://www.ebay.com/itm/new-Nikon-F-G-focal-reducer-speed-booster-adapter-to-Sony-NEX-5-6-7-FS700-FS100-/360707999952 If so, why is there the US$40 difference between the two of them??? :-/ And are the Sony E mount focal reducers just as high quality as his m4/3 focal reducers?
