No degradation except that many of the P67 lenses aren't as good as their 35mm equivalent focal lengths WRT sharpness, CA, vignetting and constancy across the frame may be better however. > In other words, what are the disadvantages to using a 67 > lens on a 35mm camera (or even the *ist D)? Apart from the optical issues there is no AF, they are huge and bulky relative to their 35mm equivalents and they must be operated in stop-down meter/shooting modes as the adaptor offers no aperture activation coupling between the lens and the body. It was fine 20years ago when I couldn't afford FL for 67 and 35mm but I wouldn't entertain the thought now. Current 35mm lenses are generally much better performers than the now aging 67 line-up (however I haven't tested any of the newer lenses as I sold off all my 67 gear late 2000) http://members.ozemail.com.au/~distudio/mfv35lenstest/ Cheers, Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications/ Pentax user since 1986, PDMLer since 1998
