Help needed:Tokina atx pro 28-70 f2.8 stops autofocus
Posted By vanchaz2002

It was mounted on K1 today. Suddenly, it can not register AF consistently. The carema will show MF and stop autofucusing after a few rotations, although all settings on camera and the lens clutch indicated autofocusing setting. I unmounted it, played around a bit, then put back on K1. It shows AF.C but revert to MF after took a few photos with successfully autofocusing. I tested on K10 with same results.

Anyone know what's going on and what will be the fix?

If the price is significantly cheaper than a Leica M9, I will buy 2.

I believe there are people like me don't care what FF Pentax would offer as long as it is a k-mount FF digital. It's better come out quick before I completely lost patient on this brand.

I will jump into a Pentax FF at any cost lower than a M9. I don't care much of the AF performance.

What do you mean limited prime? In FA series or DA?

If you mean FA, then you can get DA limited that are significant cheaper.

If you mean DA, then you may have some alternative auto focus FA/F to replace 70mm. You just need to find a cheaper copy of F/FA 50/1.7.

DA21 and DA40 have no cheaper Pentax autofocus alternatives. All good/fast FA/F ones that are wider than 25mm (DA 40 equivalent) are more expensive than DAs.

Fast Pentax manual ones in K and A are not cheaper to replace DA21 and DA 40. Half of them are much more expensive. K 15/18 are way beyond the range. K17 is fish eye and K20 is about the same price but hard to find. K28/2 is at least twice more expensive. K28/2.8 is not that great. K24/2.8 is the only reasonable one in K series. Also you can consider K24/3.5, cheaper but not always available.

No one is A lens wider than 24mm is cheaper than DAs.

For DA70, bunch of fast 50/1.4 is good alternatives.

This is apple vs. orange. K85 is $400 lens and FA77 is close to $800. When comparing lens, always have the price in mind.
