I read this comprehensive review before purchase and you should too:http://www.imaging-resource.com/PRODS/canon-eos-m/canon-eos-mA.HTMI'm an amatuer photog for more than 40 years. Until recently, my only concession to digital photography was the purchase of inexpensive Canon point-n-shoots. As film photography has become a greater burden and digital has caught up in terms of quality while surpassing in convenience and affordability, my discovery of this little gem at a bargain price was perfect timing. Adding a $15 adapter, I can use may ancient but excellent FD mount Canon lenses - think F1 and AE-1 cameras. Auto-focus speed doesn't matter to me because I still prefer to manually set almost everything. That said, the AF performance of the EOS M seems equivalent to that of my son's Nikon 1.My purchases for my entry into serious digital photography to date include: the EOS M with Speedlite 90EX and EOS M 18-55mm IS lense: an SD card (PNY 64 GB High Speed SDXC Class 10): a spare battery (Opteka LP-E12 LPE12 2000mAh Battery Pack): a lense adapter (Fotasy Canon FD Lens to EOS M Lens); and a neck strap (OP/TECH USA System Connector Super Pro A).

Filter looks fine, however the Canon lens cap for the camcorder did not fit very well on the filter, so I will have to get another lens cap.

Perfect with an adapter for my Canon SX40. Thanks!

Used in conjunction with an adapter on a canon M 50. Ace.

This adapter did the job! I can now use all my Canon, Tamron and Sigma lenses on my new Canon m50.

works really well and the adapter is perfect for using on your phone and with my Canon T6i.

The canon adapter has been unavailable for a while, so I thought I'd try this one out so I could actually use my new R5. So far it works flawlessly!

Although you will be hard pressed to find any reference to it anywhere, the 49mm is perfect for the Canon sx530 hs lens cover replacement!! Canon won't tell you that in any of it's volumes of Specs! FYI. Finally measured the diameter and hoped I was right. I was!
