Will the SMC DA* 50-135 mm f2.8 ED IF SDM suffice as an only lens?

Nope: Focal length simulator

To answer your question quickly... No. The 50-135 would be too long, especially indoors. Check the focal length simulator below.

http://www.sigma-imaging-uk.com/support/angle_of_view/index.htm

For my taste, the 18-135 is a very complete "all-in-one" lens, being wide enough and long enough 95% of the time, compact and weather-sealed. I don't own the lens, but I do like the pictures I've seen here, and i think the reviews are too harsh.

If you are a quality addict and want a top-shelf zoom lens (and plan to get more later) I would start with the DA* 16-50 f/2.8, and wait a bit for the 50-135. A 3rd party 24-70 f/2.8 could be a good choice too if you're more of a portrait guy than a landscape guy (of course you can use any focal length with pretty much any subject).

Finally, I feel I should mention Pentax's trump card: small high-quality primes. You could fit a K5 with 3 limiteds in a very small bag. How about 15+35+70mm, or 21+40+70mm?

Anyway, as Sigma's focal length simulator (above) is a landscape, here are some family portraits at various focal lengths... Hope this is useful!

8mm fish-eye



21mm

31mm (too bad it's burnt...)

also 31mm, but cropped to about the fov of the 43.

43mm

77mm (seft portrait!  )

135mm

400mm

Note that 77mm on, all the pictures are taken outside!

Also there are no tight portraits with the 21 or wider (if you move too close, a face gets distorted)...

Some a slightly cropped, mainly to fit the 9:16 format.
