Originally posted by Greeneg I think that it would have been interesting to include what sort of 3rd party lenses people use most frequently. I have 3 Tamrons, an 18-200 which stays on the camera and is my walk-around lens, a promaster 70-300 ( also made by Tamron), and a 10-24 Tamron. This gives me a pretty fair range for travel photography. Just wonder what other people use.
I've have 3 Sigma lenses I use commonly. 18-125mm as a walk-around lens, 400mm F/5.6 APO Macro for any telephoto, and 105mm f/2.8 Macro. The only Pentax lenses I use with any regularity are the 10-17 Fisheye and the FA50 for available light indoors.
I've got quite a large gap between 125 and 400 which I'd like to fill with a DA 18-200/250 WR (SDM wouldn't hurt either, but maybe that's asking too much
).
I have a Sigma 70-300 for this range now, which I don't use often...if it's a shot closer to 300 that I need, the 400mm gets top billing since it's much better optically, but 125 is a bit short sometimes. I do barely enough shots between 125 and 250, that I feel compelled to carry the 70-300 all the time, which is 500g in my bag I would gladly do without. A WR variant (of 18-200/250) would also allow me to drop the 18-55 WR, which I carry exclusively for wet conditions (on K-7 body). The DA* lenses in this range are too expensive, and I don't require f/2.8 in a zoom lens.
The new DFA 100 WR macro is very compelling, if I didn't already have the Sigma 105 in good working condition, I'd go buy it right now.
Aside from those 2 lenses, the other ones I really want are a DA*400/f4. If it could match or beat the sharpness of the Sigma 400 f5.6 APO at wide open aperture, I'd be first in line to buy it, especially if it is <$2000 CDN.
I play with the Nikon AF-S 35mm f/1.8 at work all the time, it's a great little lens and the first I'd buy if I switched to Nikon. A DA or DA-L version would be most welcome!
Now off the topic of lenses, I work in a shop doing camera sales. The K-x is a wonderful camera which I recommend as the #1 entry-level D-SLR for image quality, but once most people find out it uses AA batteries, they are turned off it immediately.
We still stock a K20D for a very good price, but it's too bulky for the entry-level customers. A camera with the sensor and body of the K-x, Li-ion battery, and weather-sealing would sell like crazy imo. We're basically describing the K200D with a Li-ion battery, so it shouldn't be too costly to produce now. The 18-55/55-200 WR are a perfect match for this.
