Personally I'd say you should go for an SMC A70-210/4. Better because you have aperture linkage.

Hi,

I'm not worried about the linkage. Just trying to get the best sharpness I can in a mid range zoom. Any ideas as to what can out preform the Pentax 50-200?

Thanks,

Ken

it'll be tough beating the A70-210 for sharpness.. anyone with this lens will agree.

what i don't understand is why the M80-200 f4.5 is looked over so much. it's an excellent lens.

Roy,

How would you rate the A70-210 against the DA 50-200?

Thanks,

ken,
i can't rate it as i don't have the 50-200.
one thing i do know is that when pentax goes FF it'll work on it.

Roy,
To some people on this forum those are fighting words but I agree. Up to this point the only lenses I have are FA and older lenses for that reason. Now I need a couple of zooms and am trying to figure out which ones I want. The first priority is a mid range zoom. the Sigma 70-300 APO looks good but am now starting to think the pentax A70-210 would be a better choice.

Any comments would be welcome.

Thanks,
Ken

you know it's inevitable about FF.. not this year and maybe not next year but i see pentax going FF within 3 years. maybe sooner.
anyway , here's some zoo shots from the 70-210

Wow! Those are great. As for FF, at the very least APS-H.

Thanks,

Actually nobody answered Ken's question.

I own this lens, and it's quite good, considering that I bought it for 30 euros in really good condition. Just gave it a little lens cleaning and f-stopped it.

Sharpness is good in range from 100-150mm focal length, stopped at f:8 or f:11.
Distortions are close to non-existing at range of 100-150mm. A bit of pincushion distortion on 200mm.
Vignetting at 200mm, but there is no light fall-off at 80mm.
Chromatic aberrations are small if you use it in this range (100-150mm, f:8-11). Anyway you can correct this in Lightroom or any Darkroom application.
Contrast is ok, a bit washed out at f:4.5, although you can use this stop up to 200mm, I would not consider it. The lens has 11 glasses so, contrast is ok!
The quality of the blur or circles of confusion, what is widely known as bokeh is awesome, as you would expect from an old lens.
The glasses are not well multi-coated so don't point it directly in sunlight, you may weaken your sensors and hurt your eyes.

If you own M42 mount lens, opening it from behind and removing the mechanism will disable the active aperture. You won't need f-stopped adapter.

If I forgot anything, tell me.
