I am considering the Pentax K-x with upgraded 2 lens kit and also "have" to decide on the color. Anybody has an olive-green one?

Oh, I am thinking about the a 17/18-50 mm F2.8 lens icw Sigma 50-150 mm F2.8 or Pentax 50-135 mm F2.8. Would that be a good match?

I had the white one, I liked it alot (recently got a K7 though). The Kx is a great little camera. The new olive green they have made available in the US is a nice looking option!

I have read many good things about the tamron 17-50mm, not as much about the sigma 18-50mm - the extra mm on the wide end can make quite a difference.

I have the 50-135mm and love it. Outstanding images come out of that lens through no fault of my own! If you never think you'll upgrade to a weather-sealed body and the 50-150mm sigma is cheaper, that is a very well regarded alternative to the 50-135mm as well. Good luck with your choice!

Yeah, I am leaning more and more towards:
- K-x, Olive-green
- Tamron 17-50 mm F2.8
- Sigma 50-150 mm F2.8

But then I forgot about the Tamron 28-75 mm F2.8. In my SLR time I used to have 28-90 + 75-300. But when I bought the 28-200 (to minimize swapping lenses) I stopped using the 75-300...
- The 50-150 equivalents actually equal the 75-300. :eek:
- On the other hand the 28-75 is not much longer than the 17-50, so probably not long enough, but also much cheaper (a little lighter) and maybe still very handy range (especially for the time that my kids don't run away that far yet).
- I could also go for the Sigma 17-70 mm F2.8-4 OS HSM to extend my reach on that side (but then I sacrifice aperture on that range...)

Guess I just have to try check out the focal lenghts to make up my mind

If the olive speaks to you, then go for it. I like the purple.

It's funny, I wound up with a GF-1 (and thus here), but I think I mis-remembered what I had originally decided on: I think I'd planned on a K-x in navy or red. That the Panasonic G-2 was available in both helped the confusion, and when I found the GF-1 was available in a nice pink, that was that.

I prefer equipment that doesn't look like everyone else's.

I didn't have time to go to the shop to day, is the olive green also shiny / metal looking?
- The pictures at pentax . com are a little disappointing to me

Some of the K-x colors are matte, while others are semi-glossy, and yet others are speckled shiny! It does look as though the Olive is a matte finish.

The 50-150mm is only going to be 75-225mm equivalent, not 75-300mm. for APS-C sensors the crop factor is only 1.5x. If you decide to get the Tamron 28-75mm remember you'll be missing out on wide angle, as that is essentially a 42-110mm lens. Some people like the range, but on digital I think most find it limiting. Have you considered the pentax 16-45mm, or 17-70mm? I had the former, now have the latter, they are both sharp at f4 (the 16-45 moreso) and are very nice lenses in their own right. The 16-45 I believe is discontinued so you'll have to find it used; they regularly go for around $250 USD used, which is a steal in my book.

Hmm, non-shining olive-green is NOK

If I would go for 28-75 then it would be next to 17/18-45/60/70 lens.

But I am leaning towards 17-50 mm F2.8 + 50-130/150 F2.8.
- and later replace my father's manual focus 50 mm F2.0 by a auto focus F1.4 to fill the "gap"

Personally I would skip the 28-75mm. It worked well on full-frame, but 42-110mm equivalent is straight out of the worst point and shoots from 5 years ago - it is just not a good range for aps-c. Looks like you're getting plenty of help over at pentax forums, so I will leave it to my friends over there from here on out. Good luck with your choices!

Thanks

FYI: My current view next to K-x
- Pentax 16-45 F2.8 vs Tamron 17-50 F2.8 vs Sigma 17-70 F2.8-4.0
and in the tele range
- Pentax 50-135 F2.8 vs Sigma 50-150 F2.8

To be exented later by for example one of these (depending on my feelings):
- Pentax/Tamron 18-250
- Sigma 50 F1.4
- Tamron/Sigma 70-200 F2.8
- Another prime lens 30-40 or > 100

Outside Japan you can only get 4 color?
- B&H showed Black, White, Red and Navy Blue

Guess in Japan colors are more hot.
- At Big Camera in Nagoya they didn't have that many colors on display

But look here:
Japanese PENTAX K-x commercial - HAVE TO SEE!!!

After the 20 year young lady you can see the olive green camera dancing.
Wait the 38 year old guy hold a olive green one, that is mine!!!

Add-on: The on the left top you can select your colors

Yes the 50-135 is big on the K-x. I found the combination well balanced though. Think of it more like you are attaching the camera to the lens, rather than the traditional attaching the lens to the camera. The balance point is definitely in the middle of the lens, but bottom line it worked for me, I found it to be a nice combination.

Thanks for comfirmation!!!

Next challenge will be fining out if I need an additional prime for portraits and if so what would be the best focal length.
- Brokeh (icw still sharp images) and practical working distance are the key parameters.

Any feeling on brokeh performance on this selection of lenses / settings (filling full frame with face and shoulders)?
- I will have to find which distance is most practical / still acceptable for me

  1. 50-135 mm F2.8 @50 mm
  2. 50-135 mm F2.8 @90 mm
  3. 50-135 mm F2.8 @135 mm - probably best brokeh from this lens, but becoming a pretty long distance...
  4. Simga 50 mm F1.4 - my original candidate, better than 50-135 @50, @90, @135?
  5. Simga 30 mm F1.4 - if 50 mm still too long
  6. Pentax DA* 55 mm F1.4 SDM - to my understand Sigma 50 mm is close to as good as and much more afordable
  7. Pentax FA 31 mm F1.8 AL Limited - to compete with the Sigma 30 mm

And people here will probably like to know how that would compare to GF1 with 20 mm F1.7 or 45 mm F2.8...

Hmm, too many questions for myself as well, sharper try:
- Brokeh of Simga 50 mm F1.4 better than Pentax 50-135 mm F2.8 @50, @90, @135?

Hey Joep, since you're in Japan surely you can find/buy all the colour combinations?
Personally I liked the look of some of the BROWN combinations : they looked bronzey and metallic, very nice indeed.
I have a G1 and some spray paint but maybe I shouldn't ... :smile:

Hi Ulfric, I got bad news, the non-standard color can only be ordered via Pentax internet site and there you pay ~20% more even before the >10% I will get additional in the shop.

So it is going to be one of these
Red,
White or
Blue

Oh, mistake, it should of course be Red, White or Black.

iliakoltsov, thanks for the links (on Pentax forum, more Pentax than Sigma fans...). I based my conclussions mainly on the following two threads:

World Championship Beach Volley 2010 in Vevey [Page 1]: Pentax SLR Talk Forum: Digital Photography Review

Sigma 50-150 & DA* 50-135 Street Shootout - PentaxForums.com

Warning: There are some real good shots, you might want to buy one. The Volleyball pictures were mainly taken with K-7 and this "profesional" 50-135 lens

Hmm, looks like Pentax 50-135 continous to be significantly more expensive than Sigma 50-150...

Now I am considering to go for Sigma instead of Pentax and because of the close focus issues insert the 50 mm F1.4 Pentax which is pretty compact and not too expensive (maybe even with a little longer Sigma 70-200 mm F2.8).
- Please disadvice me and have me stick to the 50-135...

The 50mm f1.4 is not that great for close focus.

The only advice I can give since I have never used he sigma 50-150 is that if I had to sell all my pentax gear and could only keep one lens, without question that lens would be the 50-135.

Pentax upgrades the K-x to K-r

Pentax K-r mid-level DSLR announced with brief hands-on: Digital Photography Review

Main updates (from my point of view):
  • 3" high resolution LCD
  • Assist beam for low light focussing
  • New 12 MP sensor supporting 6 fps
  • Update Live View mode with usable auto focus
  • Interval / Time elapse functionality
  • 4 AA batery AND rechargeable Lithium Ion

Not changed, but IMHO less important than first two above and some out for scope for entry level compact DSLR:
  • 16-segment metering (little out dated, even for entry level DSLR)
  • Built-in mono mic, no connection for external stereo mic (would have been nice, but not crucial for me)
  • 1280 x 720, 24/25fps (no Full HD, nor higher frame rates and low resolution, would have been nice, but not crucial for me)
  • 96% OVF (100% would have resulted in larger body and higher price, see K-5 Pro model)
  • No Weather resistance (see K-5 Pro model)
  • Other Pro features
    [*]Level indicator & corrector (icw IBIS)
    [*]Rotation IBIS (requires larger frame around sensor)​
