sigma 70-200/2.8 HSM for pentax

Nothing like good old fashioned competition to keep Pentax honest with lens quality.

I agree.

What does everyon think about 3rd party lenses? I know they wont compete with Canons L series and Nikon G and D series, but I have found, especially with Sigma EX, they are more than capable as a lens, in many ways better........My primary lens is a Sigma 24-70 DG EX F2.8 and I find it very sharp. in fact apart from a couple of Pentax kit lenses and a 55mm F1.8, my lenses are Sigma, Tamron and Tokina, all 3rd party.

So, the question is, are 3rd party suppliers inferior, or is it just "snob" value. (remember some Pentax Lenses are made by Tamron or Tokina!)
I dont think they are.

FWIW, I've seen comparisons of the Sigma 70-200/2.8 w/ the Nikon equivalent. It's definitely not as sharp...

True for the most lenses, but few exceptions - I know few serious motorsport photographers, who admit that Sigma 120-300 f2.8 outperforms their L glass for example...

I would love to use "all Pentax" glass, but only if quality, availability of focal lengths I need/want and at the price I want are all there. So in the zoom ranges, I have absolutely no remorse to go to the 3d party lenses. Tamron 28-75mm f2.8 I've been using for almost a year, and love it, I have 15mm Sigma fisheye, that is tack sharp, and for under $300 it's a true bargain... I've seen stunning results from Sigma's 70-200mm f2.8 lenses, Tamron macro 90mm is one of the highly recommended buy so many...

So for 2008, the following lenses will be joining my bag:

Sigma 70-200mm f2.8
Sigma 10-20mm f4-5.6 (unless new Tamron proves to be a better performer)

Regards,
D

I have the origonal sigma 70-210 f2.8 and wouldn't part with it, great lens. Got the 10-20 a year ago and it takes 20% of my photos (not bad considering I have 14 lenses

From what I'm told there isn't a 70/80-200 by any manufacturer that is as good as the nikon. I know of at 3 people that have considered being able to use the nikon vr 70-200 as a major factor in their move.

kenyee · 01-31-2008, 08:47 PM

Even Canon's 70-200/2.8 L glass? I thought that was at least competitive...

FWIW, I think it's going to be a tradeoff of sharpness (Tamron) vs. USM support (Sigma) for Pentax users. I'm also curious how the FA*80-200 compares, but we won't find out until the summer probably at the rate Tamron/Sigma are going :-P

philmorley · 01-31-2008, 08:48 PM

I think for some people it is snob value (I know people that "I only use L glass"). But every manufacturers have good and bad lenses, I dont think good 3rd party lenses are bad. The tamron 28-75 is great, voigtlander's !
