looking at your signature and the list of lenses that you have im quite in awe..and think that you have a serious case of LBA..
Sadly, it's all but cured unless some manufacturer (IE: Sigma) starts producing unbeatable glass. It's possible that Sigma can outperform the Pentax optical engineers, but I'm waiting to see it.
Originally posted by Tommot1965 I see that you have the FA 80-200 and the DA* 50-135...my question is how do they compare IQ wise?
I'll refer you to Adam's review of this lens:
Originally posted by Adam: If I had to live with only a single lens, this is the one I'd choose. It boasts unmatched sharpness, bokeh, and overall color rendition, as well as the Pentax-exclusive power zoom function. Image quality is like that of a prime.
I personally feel that the lens in IQ terms is on par with the DA* 50-135, but it's size and weight are substantially larger and heavier.
Fortunately, both me and my partner shoot so having two F2.8's in this range works out ok for us.
