Reddit mentions of Fotodiox Lens Mount Adapter, M42 (42mm x1 Thread Screw) Lens to Micro 4/3 Olympus PEN and Panasonic Lumix Cameras

adding to this, m42 adapters will sometimes have an internal flange and sometimes not. This is important as some m42 lenses have pins than need to be depressed for the aperture to work, and some m42 lenses have bayonets that will not work with flanged m42 adapters.

thankfully m42 adapters are cheap.

Edit:
If this is your lens then there's a pin that operates the aperture that you need to depress with the adapter.

Looking on Amazon, you can see this adapter has a flange just behind the threads, and it will depress that pin making the aperture adjustable.

This one WON'T work since it doesn't have the flange.

I use these without any issues https://www.amazon.com/Fotodiox-Adapter-Olympus-Panasonic-Cameras/dp/B002RJKVY2/ref=sr_1_17?keywords=fotodiox+m42&qid=1571926936&sr=8-17

I use a Fotodiox M42 to Canon adapter and it works perfectly. Here's the same brand but for your MFT mount.

The lens is awesome, by the way.

Thanks, Brunerww. I have decided to get the G6 for now as it will allow me more money in lenses and accessories at this time. The GH4 will probably be my Christmas present to myself!

I decided to get:

This kit with 2 lenses,

This adapter for my old Pentax lenses

This coupler power adapter

This 35MM Fotasy CCTV lens I've read so much about.

I used your affiliate link to purchase as a thank-you for all the helpful information you've given me the past weeks.

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)
   
   [Leica M - $22] (http://www.amazon.com/gp/product/B002X2IW5I/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B002X2IW5I&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)
   
   Hope this is helpful!

I'm looking to use an old 50mm lens as a portrait lens. I was thinking this lens paired with this adapter. Will I run into any issues? Do you have any better suggestions that are under $200 USD, preferably around $100 or lower?
