FotodioxLens Mount Adapter - Canon FD & FL mount 35mm SLR lens to Pentax Q (PQ) Mount Mirrorless Camera Bodies

I happen to have some very nice FD lenses that were languishing in a lonely box on the camera shelf. Since the Q takes everything with a little help, imdescided help it would have. I ordered the Fotodiox because of past orders. The fit and finish of this adaptor is very nice as expected. It also has the tripod mount that other units don't have.

Solid and well built. Does what it does and does it well. The tripod mount is a necessity when using longer lenses with the Q since you don't want that amount of weight on the mount. The 5.6x effective "magnification" (not really magnification - the sensor is area is just smaller) really makes quite normal lenses into very long lenses. But don't be fooled - even a good lens is probably not going to resolve at that effective magnification (the lens will limit you). For example, I did some moon shots with my D90 and a 300mm lens and they were sharper than the Q and a 210mm zoom (~1176mm on the Q). While it was still pretty impressive what the Q did (all things considered), the 300mm on the D90 was much better and resolved better detail than the 70-210 combo on the Q. The D90 shot was handheld with optical stabilization, while the Q was on a tripod. Admittedly though, there is some camera shake too because I didn't have a remote shutter release.So if you have old fd lenses and want to have some fun with them, then give this a try. Just don't expect optical perfection. Also note that infinity on the zoom is not quite infinity on the Q with the extender, so finding the focus can be tricky. The Q has a zoom to assist focusing in manual mode, and that is great for some things, but this live-view style manual focusing can be unforgiving (things that are dim or too bright will be impossible to focus without trial and error). For example, the moon saturates the live-view, so you have to hunt and guess. So don't expect a super zoom for action shots!
