The 16-45 I liked very much but it failed suddenly to zoom beyond around
28 and I replaced it with a Tamron 17-50/2.8 as an all-round zoom.
But a few weeks ago, after about 5 years use of the Tamron lens, I felt
with my bag and now the Tamron lens has a zoom problem. I didn't
hesitate to buy a new Tamron 17-50/2.8 lens again for only 300 euro.
I haven't done any tests but it looks like this Tamron lens is as sharp
at 50 mm as my FA 50/1.4.

Ed,
I've had a 16-45 since I bought my (now my daughter's) istD. It's a great
lens--very sharp, compact, and fast enough, especiaily with the K-5.
I was very tempted by the 17-70 because of its longer zoom range, but the
constant reports of SDM problems (which didn't seem to taper off as the lens
got older) put me off--as did the reviews of its optical quality compared to
the 16-45.
In my 60's, weight is an increasingly important variable; so my travel kit is a
16-45, a 50-200, and a 10-17 fisheye. I keep looking, but I haven't seen
anything with which I'd replace any of these.
I've considered replacing the 16-45 with my 21 Ltd, 40 Ltd, and FA 50/1.7, but
they would weigh the same amount, are less versatile, and only of higher
quality if one has achieved a pathological level of pixel-peeping.
Cheers,
Rick

Hello all!
I have the following in my bag at the moment...
Pentax K-50
SMC-DAL 18-55 3.5/5.6
SMC-DA 50-200 4-5.6
SMC-FA 50 1.4
I find that the image quality of the 50 is outstanding when comparing
to the other 2 lenses (primarily the 18-55). Not that the kit lens is
bad, but the 50 is very sharp. I attribute this to the fixed aperture
and overall better quality glass.
I'm thinking of saving for a new higher quality lens (aren't we all?).
At this point, I'm not sure which direction to take. Do I look at the
current lineup (below) or try to find a second hand older lens.
The current fixed aperture zoom lens lineup from the Ricoh site (US prices)...
PENTAX DA 12-24mm f/4 ED AL [IF] $ 699.95
PENTAX smc DA* 16-50mm f/2.8 ED AL [IF] SDM $1049.95
PENTAX smc DA 17-70mm f/4 AL [IF] SDM $ 499.95
PENTAX HD D FA 24-70mm f/2.8ED SDM WR $1299.95
PENTAX smc DA* 50-135mm f/2.8 ED [IF] SDM $1049.95
PENTAX smc DA* 60-250mm F4 [IF] SDM $1299.95
To start, I am looking at the DA 17-70 to roughly cover the same range
as the 18-55 and luckily it's the lowest priced one. B&H has it
listed for $350, Amazon $300.
Online reviews are hit and miss on this (SDM focusing issues).
I'd like to get PDML thoughts, so fire away!
Thanks!
