Reddit mentions of Fotodiox Lens Mount Adapter, Olympus OM Zuiko Lens to Micro 4/3 Olympus PEN and Panasonic Lumix Cameras

I don't think there are any universal adapters. They make specific adapters for different brands, including Canon, Nikon, Minolta, Pentax, Olympus OM, and probably others.

From what I can tell, the difference in cost is usually about 2 things:

1.) If the adapter has electrical contacts. If you are using a purely manual vintage lens, the adapter doesn't need these and will be pretty cheap. However, if you are trying to use a modern Nikon or Canon lens on a m43 camera, an adapter with contacts will let the camera and lens talk to each other so you can use auto-focus and on-camera aperture control.

2.) If the adapter has glass in it to work as a focal reducer. As far as I know, the same "multiply by 2" rules normally apply to adapted lenses. A 50mm lens from another manufacturer will act like a 100mm lens on an m43 camera, unless you use a focal reducer, which reduces the focal length and aperture by a certain magnification level.

Also as others have mentioned, while 50mm lenses are cheap and plentiful, wider angle lenses are less common and you may not save any money trying to find a vintage 18mm. So, for example, I bought this simple adapter that lets me fit Olympus OM mount lenses from the days of film on to my E-M10, and I got 24mm 2.8 and 50mm 1.4 lenses to use with it. I don't think I saved all that much money with my purchase--maybe a couple of hundred. But they're fun to shoot with. :)

First-time camera owner here. I've been reading and teaching myself what I can, but I am looking for a recommendation.

Last year I decided to buy a real camera and take a step up from iphone snapshots. After a lot of research, and the recommendation of a friend, I picked up the Olympus OM-D EM10-II. I like it a lot, and one of my favorite times to shoot are on cloudy, overcast days in the city or even at night when things are illuminated by streetlights. I've been wondering if maybe a prime lens would be an improvement over the 14-42 kit lens for that purpose. A wider aperture would allow faster shutter speeds.

I'm looking for a half-decent prime lens for street photography, ideally under $200. I did order this adapter, and if there are any recommendations, that would be awesome.

Yup. Often with great results (but remember that field of view is subject to the 2x crop, e.g., a 50mm lens will have the equivalent field of view to a 100mm lens)

You can easily and inexpensively adapt lenses with manual focus, aperture, and zoom controls to a mirrorless body with a dumb adapter like this. There is a crop factor of about 2 between 35mm and m43 with this type of adapter. For somewhat more money, you can get a speedbooster that has optics to reduce the crop factor and increase the aperture. Somewhere in between are adapters with no optics that let the camera control some aspects of AE/AF lenses.

Oh, and stop by /r/m43 for m43 focused discussion.

Hi /u/MexicanWithTaco - the camera can be adapted to just about any lens ever made, so it really depends on what you can afford and whether you prefer to shoot manual or auto.

For auto lenses, there are two major choices:

1. Micro 4/3 system lenses from Panasonic, Olympus and Sigma. The least expensive of these (besides the classic [14-42 lens] (http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575034783&toolid=10001&campid=5337235943&customid=&icep_item=191134243148&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg) that is the earlier version of the [lens that comes with the camera] (http://www.amazon.com/gp/product/B00B7FOVAM/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00B7FOVAM&linkCode=as2&tag=battleforthew-20)) are the [$199 Sigma 19mm f2.8] (http://www.amazon.com/gp/product/B00BPZCYK8/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00BPZCYK8&linkCode=as2&tag=battleforthew-20) and [Sigma 30mm f2.8] (http://www.amazon.com/gp/product/B00BQXL6OY/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00BQXL6OY&linkCode=as2&tag=battleforthew-20). You can find them for even less used. These lenses are very good value for your money.
   
   
2. Classic 4/3 lenses from Panasonic, Olympus and Sigma with a [Panasonic MA1 adapter] (http://www.amazon.com/gp/product/B001ISKNKK/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B001ISKNKK&linkCode=as2&tag=battleforthew-20). These are lenses from the Panasonic/Olympus attempt (about 5 or 6 years ago) to build a standard mirror-box DSLR that would go head to head with Nikon and Canon crop-sensor DSLRs with a slightly smaller sensor and marginally smaller cameras.
   
   In 2009, they went for broke, removed the mirror and created a line of much smaller and lighter mirrorless cameras which, incidentally, turned out to be much better suited for video than DSLRs. But the transition "orphaned" dozens of great 4/3 lenses that, with the adapter, work well with micro 4/3 cameras. I have a [Sigma 18-50mm constant f2.8 lens] (http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575034783&toolid=10001&campid=5337235943&customid=&icep_item=181378147578&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg), for example, that cost me a few hundred dollars instead of the $1000 for a modern [Panasonic 12-35mm f2.8] (http://www.amazon.com/gp/product/B00855ZL38/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00855ZL38&linkCode=as2&tag=battleforthew-20). The autofocus motor is a little noisier and slower than a modern lens, but it costs a lot less.
   
   For manual lenses, there are modern and classic choices as well:
   
   
3. The modern choices are micro 4/3 cinema lenses from SLR Magic; Rokinon/Samyang/Bower and Zeiss. These are cinema-style lenses with gearing for follow focus devices, clickless aperture measured in T-stops rather than f-stops and large silk-screened numbers on the lens barrel to help with focus and aperture setting. These lenses range from [$349 for a Samyang 85mm T1.5] (http://www.amazon.com/gp/product/B00IVQ6VNK/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00IVQ6VNK&linkCode=as2&tag=battleforthew-20) to [$23,900 for a Zeiss Compact Zoom] (http://www.adorama.com/searchsite/default.aspx?searchinfo=Zeiss+Compact+Prime+CZ+MFT&KBID=66297).
   
   
4. The classic manual lens choices are almost infinite. You can put just about any lens ever made on a micro 4/3 camera with an inexpensive adapter:
   
   [Nikon G - $23] (http://www.amazon.com/gp/product/B003TROEBM/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B003TROEBM&linkCode=as2&tag=battleforthew-20)
   
   [Canon EOS - $32] (http://www.amazon.com/gp/product/B007KG4QKC/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B007KG4QKC&linkCode=as2&tag=battleforthew-20)
   
   [Canon FD - $16] (http://www.amazon.com/gp/product/B003MDWG68/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B003MDWG68&linkCode=as2&tag=battleforthew-20)
   
   [Olympus OM - $22] (http://www.amazon.com/gp/product/B002TSWTAA/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B002TSWTAA&linkCode=as2&tag=battleforthew-20)

   [M42 - $16] (http://www.amazon.com/gp/product/B002RJKVY2/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B002RJKVY2&linkCode=as2&tag=battleforthew-20)

/u/iamdw88 - congratulations on the f.Zuiko OM lens. Yes, the [£27.95 Fotodiox OM to MFT adapter] (https://www.amazon.co.uk/Fotodiox-Adapter-Olympus-Thirds-Panasonic/dp/B002TSWTAA/ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=hybrcamerevo-21) will work, but this [£11.99 adapter from XCSOURCE] (https://www.amazon.co.uk/d/Camera-Photo/Lens-Adapter-Olympus-Micro-Camera-E-PL3-DC116/B008H2HZ7O//ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=hybrcamerevo-21) or this [£15.99 adapter from K&F Concept] (https://www.amazon.co.uk/d/Camera-Photo/Concept-Lens-Mount-Adapter-Olympus-Micro-Camera/B01172WA9I//ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=hybrcamerevo-21) will cost you less and both have been more favorably reviewed.

Hope this is helpful, good luck with your new lens and Happy Christmas to you and yours!

>... what camera do you recommend, as a lightweight mirrorless to use with vintage glass?

I can't. If you want lightweight, you have to get a smaller camera with an APS-C or 4/3 sensor, and if you want to play with vintage glass, full frame is best, which puts you back into the dSLR-carry bulk stakes. Because you're carrying both the lens and the camera body.

Mirrorless only makes the body smaller. And you're complaining about the bulk of an f/2.8 zoom. Have you tried putting the EF-S 24mm f/2.8 STM pancake or 50mm f/1.8 STM on your SL1? Also note how the Metabones adapter is about 1/2 the length of the 50/1.8 on the A7.

Most vintage lenses you're going to find were designed for 135 format (35mm film/full frame) SLRs. Unless you're deliberately pursuing half-format lenses or old 35mm motion film lenses or rangefinder lenses (all of which are harder and more expensive to find than, say, Minolta MC/MD or Canon FD/FL), you're liable to end up with an even bigger combo than your SL1 + a prime, particularly if you need something longer/wider than a 50mm lens.

And using lenses designed for 35mm on 4/3 or APS-C is a PITA when it comes to wide angle, because even a 24mm was an expensive exotic wide angle back in the day, and an 18mm will require a ton of time to find and probably cost more than a digital-era lens would. Do the crop math.

You're mostly going to have to give up one (weight/size) or the other (vintage glass adapting). Just saying, be sure you're going into the vintage glass because you really are willing to give up autofocus, aperture control from the body, lens EXIF, wide-open metering, etc. etc., for the vintage feelz, and not just to save a few bucks. And also realize you're kinda looking for a unicorn if you expect to put 135 format lenses onto micro four-thirds and be happy.

I have routinely used both a Summicron-R 90mm and a C/Y Planar T* 100/2 on my 5D MkII where they are big and heavy and balance nicely with the big heavy body and work well with the full-frame sensor. And I only ever once tried to put them on my GX7, because 200mm and 180mm equivalents aren't that great for zoo/wildlife use when they don't autofocus, and they're not wide enough for general walkaround use. Also, nose-heavy. I do use my OM 50mm f/1.2 on the GX7, but it's still nose-heavy, given how thick the adapter ring is, and still a 100mm-equivalent lens.

I live in the U.S. Would [this] (https://www.amazon.com/Fotodiox-Adapter-Olympus-Panasonic-Cameras/dp/B002TSWTAA/ref=sr_1_fkmr0_2?ie=UTF8&qid=1466624709&sr=8-2-fkmr0&keywords=Lens+Adapter+for+Olympus+OM+Lens+to+Micro+4%2F3+M4%2F3+Camera+GH3+GF3+E-PL3+E-P3+DC116) work?

Also, this lens was being used with a canon camera (probably should have mentioned this before). Does that mean this has a canon mount?
