nerp Posted December 30, 2016 Share Posted December 30, 2016 M42 adapters to Sony E-mount are commonly available. A popular one is https://fotodioxpro.com/collections/lens-mount-adapters/products/m42-snye. Cycledoc 1 Link to post Share on other sites More sharing options...
Username Posted January 7, 2017 Share Posted January 7, 2017 You're in luck. Two major drawbacks to cheap adapters are crappy front flanges and crappy bayonet latches. The M42 mount needs no latch, and the threaded front flange is almost impossible to screw up quality-wise. The other thing money might buy you quality-wise is a less reflective interior of the adapter. So don't buy blind on eBuy. Buy from a vendor that answers their phone and tell them you want an M42 adapter with an anti-reflection lining. You may wind up spending $30 instead of $15.

aliengrove Posted January 7, 2017 Share Posted January 7, 2017 The adapters from K&F Concept are cheap and work very well. I have Minolta MD, Pentax K and M42 adapters from this manufacturer and all work perfectly on my A7rii and A7s. They also work well when shooting IR. I don't see any point in paying loads more for the Novoflex adapter. Link to post Share on other sites More sharing options...

zahtar Posted January 20, 2017 Share Posted January 20, 2017 Hello, first post here! I am looking for such an adepter as well (M42 to NEX) for my a6000. I've seen the following two types. http://www.ebay.com/itm/M42-NEX-Objektiv-Adapter-Ultra-Slim-fur-M42-an-Sony-E-mount-NEX-7-NEX-5-NEX-3-/152382560715?hash=item237ab559cb:g:YNUAAOSw9GhYbMty http://www.ebay.com/itm/M42-Screw-Mount-Lens-To-Sony-E-Adapter-NEX7-NEX5N-NEX5C-NEXC3-NEX3-NEX5-DC108-/262579654624?hash=item3d22f78fe0:g:bbMAAOSwaB5XsmJE Is it possible that they both work correctly? I mean focusing at infinity etc? Has anyone tried the slim version? It does not advertise infinity focus. The two above are just for reference regarding their dimensions. I understand and agree that buying blindly from ebay has its risks. Are there any other brands that anyone can recommend besides K&F? Thanks in advance!

zahtar Posted January 22, 2017 Share Posted January 22, 2017 Aliengrove, thanks for your reply! The links I gave above were just for reference regarding the adapter dimensions. I looked up some K&F on ebay and saw there are various designs, and possibly qualities? For example: http://www.ebay.com/itm/K-F-Concept-Lens-Mount-Adapter-M42-NEX-for-All-M42-Screw-Lens-to-Sony-NEX-Camera-/361468280385?hash=item5429303e41:g:i~EAAOSwoydWl2KY http://www.ebay.com/itm/K-F-M42-NEX-Copper-Adapter-for-M42-Screw-Mount-Lens-to-Sony-NEX-Camera-/201701616245?hash=item2ef65a6a75:g:qWwAAOSwal5YErD6 The body mount is different, so the idea I get is I don't want to have scraped shards of metal or paint near my sensor The four k&f adapters you tried looked more like the first or second design? Thanks again! Link to post Share on other sites More sharing options...
melovesushi Posted May 7, 2017 Share Posted May 7, 2017 i use a7ii and fotga m42 adapter, this cheap adapter has no lip/flange so it is very useful for using the much older m42 lenses, older m42 lenses back element protrudes into the adapter hitting the flange or lip of other adapters damaging the back element. if you get a fotga make sure you order one with a hex key for adjusting/correcting how the lens sits ,which is easily adjusting by undoing the 3 lugs . KF are much better built but have the lip not sure about the new ones Link to post Share on other sites More sharing options...

Username Posted May 9, 2017 Share Posted May 9, 2017 ......even in infrared (some adapter coatings don't work with IR) What is an "adapter coating" ? Are we not talking of simple empty tubes, with fancy ends ? Link to post Share on other sites More sharing options...
aliengrove Posted May 13, 2017 Share Posted May 13, 2017 What is an "adapter coating" ? Are we not talking of simple empty tubes, with fancy ends ? The interior coating of some adapters allow light to reflect off the inside of the adapter. I have had 3 adapters where this is a real problem in infrared.

Username Posted May 13, 2017 Share Posted May 13, 2017 The interior coating of some adapters allow light to reflect off the inside of the adapter. I have had 3 adapters where this is a real problem in infrared. Interior anti-reflection treatment. My dumb. My mind went right to optical coatings, which acoarst also deal with reflections and I knew you meant an empty tube adapter, not a SpeedBooster adapter with optics. This still leaves me a question. What you refer to as "problems with IR" is not especially limited to IR. Reflective inner walls are gonna be just as much grief with visible spectrum, no ? IR was a much bigger challenge, reflection-wise, when it was film, cuz it had no anti-reflection light-absorbent anti-halation coating on the back of the film [there we go with "coatings" again]. AAMOF I don't bother with digital IR shooting cuz the highlight bleeding on film [halation from bounce-back] was a major part of the fun ! I can imagine that some interior coatings are not IR-opaque so maybe the IR bounces off of the metal tube wall, where visible spectrum does not ? Is that the coating problem ? Maybe the interior blacking in some lenses is also ineffective with IR ? That acoarst would also happen equally with film as with digital, altho digital might be "more than equally" ... cuz if there's scatter from the lens walls, then you have the shiny sensor pack bouncing it back up to the rear element and back to the sensor again, but at least film wasn't shiny-as-glass. Maybe consider giving up tubes and glass altogether, and just mount a pinhole into body cap :-) Longer waves ! Link to post Share on other sites More sharing options...
zahtar Posted May 13, 2017 Share Posted May 13, 2017 thank you for your replies. I got a cheap 7$ no name adapter which holds the lens on the camera firmly, but makes the distance scale a bit off. I'll keep the k&f in mind just in case. Link to post Share on other sites More sharing options...
aliengrove Posted May 30, 2017 Share Posted May 30, 2017 thank you for your replies. I got a cheap 7$ no name adapter which holds the lens on the camera firmly, but makes the distance scale a bit off. I'll keep the k&f in mind just in case. I should have said that the K&F adapters are the only cheap ones I have been happy with....but if the one you have works, no problem. Watch out for paint/coatings scraping off the adapter when you attach it to the camera. The K&F ones I have bought have never had this problem as they are anodized but two other cheap ones did.

nerp Posted July 29, 2017 Share Posted July 29, 2017 Being a long-time Pentax shooter, I have quite a few Pentax K-mount and M42 lenses as well as several M42-to-K adapter rings. So when I got my a6000 I got only the K-to-E adapter, and I attach the M42 lenses to it using the adapter rings. That way only one lens adapter is needed for both K and M42 lenses. If you want to do that I recommend getting the genuine Pentax adapter rings. They're more expensive ($35-40), but they fit the K mount better and have less chance of getting hung up in the K adapter than the knockoff brands do. zahtar 1 Link to post Share on other sites More sharing options...
nerp Posted July 29, 2017 Share Posted July 29, 2017 Forgot to say, most of my adapters are K&F, although I have one Kiwi for Nikon F and one generic for LTM. I'm very happy with the K&F adapters, but I haven't used the Kiwi enough to make a final judgment. zahtar 1 Link to post Share on other sites More sharing options...
zahtar Posted July 29, 2017 Share Posted July 29, 2017 Thanks nerp! k&f adapters seem to be getting lots of love! I don't have different pentax lenses, so different adapters are not an issue. I just want to gather opinions about brands which make adapters that function properly, keeping the distance scale indicating correct values (for zone focusing, hyperfocal distance etc). EDITed once again: I just noticed that the links in your post were automatically added by something called VigLink. Quite a misleading function of the forum...
