I intend to buy a new lens online but I want to make sure it is fully compatible with my Pentax K200D. How can I be sure? THis is the new lens that I was planning to buy for it:
The Tamron SP AF28-75mm F/2,8 XR Di


Tamron -28-75*mm F/2,8 (modèle A09)


Thanks in advance

As long as the one you pick up is the Pentax Mount Version. It's a very good lens for the price see the reviews

The 70 to 200 is a different lens... the OP asked about the 28-70.

There's a lot of variation in these - check it for sharpness and focus accuracy when you get it. If it's off, then take it back for an exchange. I tried two and both were bad, I ended up getting the 17-50mm Tamron instead, and I don't regret it at all.

Actually this is a lens I intend to use for model shooting and the range 70-200 may be a range too much...But thanks anyway for the suggestion!

[Neel1]

I already have a 70 to 300 mm lens....

[Neel1]

Yes indeed the 17-50 mm is very sharp and I will be a bit short range with it when shooting models outdoor: Tamron -17-50*mm F/2,8 (modèle A16)

Thanks for all the suggestion

clicked the wrong link advice is the same though

I opted for the Sigma 24-70 2.8 in this range but i think the tamron is as good

If I wanted a portrait zoom i would lean to the DA*50-135 pentax but it's pricey (I prefer a prime for portraits myself a fast 55 on apsc or a fast 85 on 35mm

It will, if it's the proper mount. Check the package or ask the seller, if it says "K-Mount" or "For Pentax" then everything is good, plug-and-play.

When I asked the seller, he told me that I can't use the Tamron 28-77 mm F2.8 at wide angle on my Pentax K200D....Is that so? I mean why is that so? Do you think it's still worth acquiring for my Pentax K200D?

28mm is not very wide on a digital SLR because the sensor is smaller than the 35mm film size that the lens was designed for, so there's no sensor at the edge of the image circle to collect the light. It's an equivalent of 42mm, which is close to a "normal" focal length on digital.

As I recommended earlier, if you want proper wide angle, look for the Tamron 17-50mm, f/2.8 instead. It should cost about the same and will be a better all-round focal length range. It's an excellent lens.

That's a very clear explanation! Thanks...The problem is that I will be using that one for model shooting essentially and in practice, I rarely use a wide angle like 18 mm....28mm would have been great but I often need above 50 mm too. I normally shoot outside, so I don't need to be too close to the subject. I was just wondering as from what range the lens will be usable on my K200D?
