Looking for an entry telephoto.

I found this Sigma AF 75-200mm on eBay, would this be a good start for just playing around?

Thanks!

The Tamron 70-300 - it's a great performer, and, unlike most less expensive zooms, is sharp at 300mm. It's around $200 new.

What I mean by expensive is a constant aperture zoom, like the Sigma 70-200/2.8 or the Pentax FA* 80-200/2.8. Those are much more...

Otherwise you're better off with the Pentax 50-200, which is a great little performer.

Cheers,
Marc

Hi Scott

I agree with Marc. Get either the Tamron 70-300 LD Di or the Pentax DA50-200 if you are on a budget. Pentax is more compact but only goes up to 200mm whereas the Tamron goes up to 300mm but it is bulkier (but not too heavy).

cheers

IIRC isn't Quantaray a rebadged Tamron? And if so, would this be the lens?

Scott,

Someone today just happened to mention that he owned one of the Quat lenses and he specifically told me that it was the Tamron incognito. I can't swear for sure that it is but I believe I have heard this said before. If you go to Photozone.de you can check the Tamron version out and the lens test that shows how really good it is for the money.

It is surprisingly sharp through 200 mm in both center and edge sharpness for the price. Centrally it is pretty good at 300mm but the edges will get pretty soft on you at that focal length. That said, doesn't one usually focus centrally at longer focal lengths. If you want it sharp at the edge at 300 you can pony up another $1000 and get the sharpest zoom tele that Sigma makes... the 100~300 f/4.

Why is it there is always a trade off in life?
Let us know what you do.
Stephen

Hey Scott,

Sorry to make you jump around a bit. If you follow this link below, it should answer your questions regarding the Quantaray lens.

https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/2714-quantaray...ed-tamron.html

There is another link in there that should point you in the right direction.

There is a user here who picked up the lens. Just trying to remember. When I do, I'll repost for you.

Cheers!

the sigma 70-300mm 4-5.6 dg macro is a nice choice for a lens too, it is rather big though. but for the price the picture quality is pretty good.

DA 50-200mm f4-5.6

Unless you need a longer reach than 200mm, you simply can't beat the Pentax DA 50-200mm for the price. It is an amazing little lens, very sharp when stopped down a little, and it is quite compact as well. Oh, and its bokeh seems very nice to me.

Here are some of the first shots I took with it a little over a week ago. All straight out of the K10D, in 10MP *** JPEG mode:

1/400s, f/7.1, ISO 100, 160mm, +0.7EV


1/500s, f/8.0, ISO 100, 200mm, +0.7EV


1/400s, f/7.1, ISO 100, 200mm, +0.7EV

I know nothing about the Sigma 75-200. It looks a bit clunky but for $50 it could be OK :-) Heard some good things about the Tamron LD Xi Di (or what ever they call the groovy one.).

I do know about the Sigma 70-300 f4-5.6 DG Macro... there are a few versions of it and supposedly the "APO " version is the only "good" one. It makes you pretty conspicuous when it is extended over 10 inches, however...

I agree with RBellavance that the Pentax 50-200 is an excellent choice if you don't need 300mm. It seems a bit sharper than the Sigma, though lacks the close focusing ("macro") ability.
