Lens for Canon EOS 500D

[Tom]

It's for lenses that use Autofocus. It communicates with the camera as to when the image is in focus. As the lenses you are looking at won't have autofocus, it's unnecessary.

Here's the Takumar on my 5D, and the Helios on the Zenit

Cheers for the help.....now to bid for a lens... This is more fun than buying new you don't know what you get until the item arrives 🙄 and if it works lol.

Make sure there's no (or very little) dust, moving parts are nice and smooth, the aperture blades close up properly and they're not covered in oil. If they don't say on the listing, might be an idea to send them a message. Car boot sales are fantastic too, that's where I get almost all of my gear from, and it's so cheap when people don't know what they're selling!

If you have a look on my flickr I did some lens tests with the Helios on the 5D. Lovely at wide apertures, and super sharp closed down
