Hello everyone. Yesterday, I finally received my M42 to EF adapter and figured I'd share my thoughts for anyone considering something similar.
The Auto Focus (AF) Confirm Chip and EF side of the adapter:
The M42 side of the adapter:
The EF Lens cap that came with it (I wasn't expecting one!):
A Little History:
This adapter allows me to use old M42 screw mount lenses on my Canon DSLR. The reason I wanted this is because M42 lenses are CHEAP and you can get quality glass for great prices. The M42 is a "universal" lens mount, meaning it was used by several camera manufacturers (Pentax, Mamiya-Sekor, Cosina, Olympus, etc.), so there's a good supply available online. However, these are manual lenses. No auto focus, and you have to set the aperture with the ring, not with the camera. So it's not for everyone.
First Impressions:
The adapter seems fairly well made. It's black, so it blends in well with the camera. Everything seems to fit nice and tight. I don't see any problems with light getting past the adapter, which was one of my main concerns.
The ad guarantees that the adapter will allow for infinity focus. That's one of the main problems with cheap adapters. I asked several sellers before deciding on Roxsen and they all said they would not guarantee infinity focus (well, at least the few that responded.) If you can't get infinity focus, you can't take landscape pictures. You're limited to things close to the camera.
Along with infinity focus, they also promised the camera would be able to alert me with the familiar red lights and beep when I was in focus. Since the focus screen on my 300D leaves much to be desired, this was a big selling point for me. It does have an AF Confirm chip glued to the surface of the adapter. I am a little concerned that with many lens changes may result in that chip falling off. Right now, it feels quite secure. It looks like they used epoxy, so my fears may be unfounded.
First Test:
Using the adapter is easy. Screw it onto the lens, then attach the lens to the camera like any other lens. The fit to both the lens and the camera is excellent. I'm very impressed. I was worried because it came from a Hong Kong seller; they aren't known for quality products.
When the lens is attached, the camera reads an aperture of f/1.4 regardless of what the aperture ring on the lens is set to. There were other sellers offering adapters that you could set the f/#, but since this doesn't affect the picture, just the EXIF data, I wasn't that concerned.
Here's a test shot of my niece. The AF confirm seems to work as advertised.
And here's a test of the infinity focus (I know, crappy picture... it's a test shot!):
Final Thoughts
Overall, I'm quite pleased with my purchase. The adapter was $12.99USD with free shipping. It took exactly two weeks to get here from Hong Kong, although the seller says it can take up to 30 business days and some negative feedback had items arriving more than 40 days out. I can't complain about two weeks from the opposite side of the world. The seller (Roxsen) answered all of my question within 24 hours of asking.
I can't wait to get more M42 mount lenses. Time to play!
