What options do we Pentaxians have for a 70-200?

Hi,

I use a Pentax K100D ( ) and an MZ-S for BW film. I really envy the Canon guys with a two zoom solution for the most used flengths, the 24-70/2.8 and the 70-200/2.8. We Pentaxians have only the Tamron and Sigma 70-200, the first known for focus issues and the second for so-so IQ. There is the FA * 80-200, but rarity rulse it out.

So, what do we have in the 70-200 range? FF is important to me.

I don't consider the Sigma 70-200/2.8 "so-so IQ". Those from the C@n0n world have always been saying that pictures made with this lens are almost indistinguishable from 70-200L.

If you really don't like the Sigma, try Tamron - you can always return bad copies and eventually you'll get one without any focus issue.

The Tamron I recently picked up is just fine and it's about a month old.

what focus issues ?

I know that the TAMRON has a slow AF speed and a tendency to hunt in very low light (with K20D) but I wasn't aware of focus issues. I have one and I have no issue at all.
About IQ, very impressive.

About the range of zooms on the pentax shielve, I think we have good glass too with 16-50 and 50-135.

Canon has 24-70/2.8 + 70-200/2.8 pro lenses for their pro FF bodies. Pentax has the 16-50/2.8 and 50-135/2.8 for their APS-C bodies, which have equivalent field of view to 24-75mm and 75-202mm lenses on FF.

As for a 70-200 that would work well on both your K100D and MZ-S, your choice is somewhat limited by your K100D not supporting HSM, which rules out the recently announced Sigma 70-200/2.8 OS HSM (with FLD glass). Id look at the Tamron 70-200/2.8, it seems to have the best IQ at 200mm.

Not sure what you meant. You are allowed to shoot film using Canon or Nikon cameras, right? and also shoot digital, FF or APS-C.

Hi

If you really want one and you do not want to go Tamron or Sigma then switch...or at least get a camera and THAT lens to see if you wanna switch.

While I would LIKE a Tamron, Sigma or Pentax FA, I recently got a old Tamron 70-210 3.5 adaptall (19ah) and it is good if you do not mind manual focus....only half a stop down for a fraction of the price (some fringing) but it IS full frame and if you got one in the interim if you ever swap systems you can take it with you as a spare.

I am happy enough to not seriously think about the af 2.8.

There is also a Tamron adaptall 2.8 but that is rarer and still goes for a fair amount...though is supposed to be excellent...again ff and could be taken with you if you change.

Just a thought.

The Tamron has a reputation for slow AF on OTHER mounts where it has an in lens motor. On Pentax it uses the screw drive and is quite snappy on the bodies with stronger motors, like the K-7.

My Tamron 70-200 f/2.8 works great

I have the Tamron 70-200 f/2.8 and use it with both my K-7 and K20D. I haven't noticed any focusing issues nor do I find it to be unreasonably slow at AF even in low light.

I think we need to stop taking lab tests so seriously. They don't reflect the real world. I wonder how many lenses we miss out on because we let lab tests or reviews scare us off. Likewise, I wonder how many times we buy bad lenses because lab tests and reviews praised them more than they deserved.

As far as I'm concerned, the only valid lens or camera tests are based on my own on hands experience with the gear.
