Originally posted by voyager13 Hi Vasyl, perhaps I may be wrong, it may be 30 cms for the M. The 80 cms for the A sounds right. If those two distances are right, and I think they are, the question still remains why is there a difference in the focusing distance using the same focal length of 28mm?
because one is a zoom and it is a compromise made for zoom design. the question was answered i thought above.
the A28 prime does focus to 30CM (no surprise it's almost the same lens)
in fact aside from the K28 F 2 which focuses to 25 cm all K mount 28 primes (k/M/A/F/FA) focus to 30CM. the tak 28 3.5 is 40cm
Zooms will vary depending on the level of compromise and what they want to acheive (just like a 70-200 zoom is really only 200mm at infinity and at closest focus is probably closer to 135mm)
this is one of the reasons for shooting with primes
