none exist? umm.... about 25 million PK mount FF lenses do exist. They are called the SMC Pentax K,M,A,F,& FA series lenses and that's not even counting the many third party FF K mounts. Not all of them would be suitable for FF digital of course for a number of reasons but I bet the number is NOT zero. Some of the best digital suitable PK lenses on FF will probably kill their DA equivs for sheer format size reasons.
FF lenses don't need be "not restricting the FF sensor performance" to necessaarily beat the APS system performance. In other words, if they choose to make the FF sensor at same pixel density at the best APS sensors, that doesn't mean the FF lenses would have to be non resticting the sensor to still end up with higher overall system resolution than the best APS sensors and lenses system performance, the format size difference can swamp the other parameter differences. -- J.C.

A few at most. > -- > J.C. O'Connell (mailto:[email protected]) The question is 'how many of these cheaper non-DA lenses exist' and the response is none. Nor do they exist in the three systems that offer both APS-C and FF bodies. Nor will they exist anytime soon. The reality is you're going to pay around double for FF lenses which do not restrict FF sensor performance with current sensors than you will for APS-C lenses which do not restrict current APS-C sensor performance, this applies to normal and wide zooms as well as wide primes (there are plenty of normal and longer primes and telephoto zooms which are up to both APS-C and FF sensors, but there's no money to be saved there either since the ones which can perform adequately on only one type of sensor are doing so on APS-C). -- M.
