FA J lens opinions
If you're shopping for lenses, I would recommend you include the Tamron SP AF 28-75 F2.8 XR Di as part of your research.
I have recently purchased the Tamron lense as a replacement for the Pentax and feel that the I am getting a better performance from my camera than ever before.
At the photo shop, the Tamron lense was was initially demonstated on an *ist and I found the focus fairly quick and accurate. From a physical perspective, I was very comfortable with the feel and handling of this lense, although it is dimensionally larger that the older Pentax.
To date, I haven't been disappointed with any of the results using the Tamron lense.
Good luck!

I must admit, I am not a fan of most of the indepedent lenses. Generally, I have found the Pentax ones to give better results on an equivalent match. The Tamron SP AF 28-75 F2.8 XR Di is in a different league to the budget Pentax's. However at this price bracket and quality, I would go for the Sigma 28 - 70 EX. Personally, I will stick with my FA* 28-70/2.8 AL - apart from the size,it leaves all the others miles behind.

I can vouch for the 24-90mm, which is a cut above the basic zooms in the range. I have also tried the 28-70mm f4 AL, which is pretty good as well. Of course, KIm, your 28-70mm f2.8 is a different kind of beast! If I could justify the cost of that, then that would indeed be a lens of choice.
Independent lenses have always been a disappointment either mechanically or optically and although there will no doubt be good ones I tend to avoid them. In any event, they tend to focus or have aperture rings that turn the wrong way and that causes confusion in practice.

The smc FA J 18-35mm F4.5.6 AL has it's own thread below - and general opinion seems to be that it has some minor problems - but these are minimised when used on the *Ist D beacuse of it's smaller sensor size.
What about the other two in the range, the smc FA J 28-80mm F3.5/5.6 AL and the smc FA J 75-300mm F4.5/5.8 AL? does anyone have any opinions - or can point me to a review?
Many thanks,
Andrew
