PixcoPro Focusing Infinity Speed Booster Focal Reducer with Optical Glass Adapter Lens Turbo M42 Mount Lens to Micro four thirds M4/3

Great love it ! fast shipping !

The item arrived nicely packaged. The adaptor looked to have a nice finish too. That is the good. On to the problems. First of all the lens would not click lock securely into either of my LUMIX camera bodies. I reported this to the Support email included with the packaging. Compared to mother lens adaptors the pin which triggers the click/lock was substantially shorter than my other lens adaptors. I included this detail in my support email. The response was to change the adjustment on the lens group. This did not solve the problem and added another one, a lens coil no longer focus to infinity. After another exchange of emails I asked for a replacement adaptor which went unanswered. Nice packaging, nice finish, reasonable price but final quality check and customer satisfaction are not considerations. Never buy this product is my suggestion.

I like this product and use it regularly. I used it this morning with a Zeiss Jena 20mm M42 lens. The images produced with this speed booster and all of my lenses are very nice. The Pixco adapter fits my Panasonic G9 camera and lenses very well. I bought a more expensive Zhongyi unit first, and it was low quality with significant play at the camera and lens mounts. The Zhongyi is expensive junk. I recommend buying the much less expensive and much higher quality Pixco adapter.

A great option to utilize my legacy Takumar lenses with the focal length adapted for M43. I was surprised at how well the optical concentrator functions at maintaining a relatively close perspective of the original legacy lens. Keep in mind to determine the corrected focal length of the lens with the adapter you divide the legacy focal length by the M43's aspect ration to the 35mm film frame; This result is then multiplied by 0.71 (the adaptor's correction ratio) and this will be the corrected focal length.

Use it on Olympus E-M10 (both Mark I and Mark II) with 2 Russian M42 lenses. Works perfectly with both, mounts exactly on the camera, screws perfectly on the lenses. Not sure what other reviewers are smoking...
