Standard zooms for the smaller formats are often equipped with rather large maximum apertures. The quality may actually be quite ok, but of no use for an APS-C or FF camera <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

The Mamiya Sekor is ok, provided it is the multi-coated version. I don't know M-S well enough to be able to tell you straight away, however <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />. Most 50-55 mm lenses from the analog days, provided they have apertures no larger than F/1.7, tend to be quite good. The optical designs used are actually still used today, except for lenses like the F/1.2s and faster, and the Sigma 50 F/1.4. They typically perform better up to about F/2.5 than their faster brethren (the F/1.4s). At F/2.8 the F/1.4s normally get better, up to about F/5.6, and then from F/8 they tend to be equal again.
If you pay a really low price for the Danubia, it may be worthwhile as a novelty gadget. Don't expect too much from it.
The Dixi is likely one of the many advertising brands only, and this company likely got their stuff from a variety of manufacturers, whereever they could get it cheapest. Could be Cosina, the cheap stuff that is, or almost anything else. If the coating looks green, it is probably a Cosina, if it is bluish purple, it could be anything.
Kind regards, Wim

Thank you. Not sure how to tell if the Mamiya is multi-coated, it doesn't say on the lens. Attaching shot of the front. Does the 'Auto' mean it has autofocus? Not that I expect it can be adapted, of course.
I guess I should get a couple adapters first, so I can try them out in store. The T2 is trivial enough, but I'm seeing a huge price variation in M42 chipped adapters, from $100 down to [url="http://cgi.ebay.ie/AF-Confirm-M42-Lens-Canon-EOS-Adapter-fr-550D-500D-/180519096223?cmd=ViewItem&pt=UK_Photography_CameraLenses_Lens_caps_hoods_adaptors_ET&hash=item2a07c6cf9f#ht_1052wt_1139"]this one[/url] for 19 pounds. Having only one body, I'm a little skittish about crappy hardware possibly damaging it. Anybody got experience with chipped M42 adapters?
