Another which lens thread ....da 50-135mm or tamron 70-200mm?

Hi all,
So which one? I am looking at portrait type stuff. I have a sigma 28-70 which I love but find I need just a squidge more length and compresion on occasion......both lenses have good ratings.......except for the SDM issue.......which slightly puts me off the DA.
I would have to buy them from the US as the savings are significant ( I am in OZ ) which brings up the warranty issue as well.
The tamron is larger and heavier........but I already have 77mm filters....the DA is smaller and quieter but MAY have issues with focus and the SDM........phooey I cant make a decision!
cheers
Jan
PS, and then there is the Sigma 70-200 2.8 as well.........

I used to have both, but only for a while....
If it's for portraits only/mainly, I'd recommend 50-135, or you have the 3rd option of Sigma 50-150/2.8.
Frankly, the Tamron is great lens, but it's tad too large and heavy (for my liking anyway, but then I'm mainly prime user). DA* or the mentioned Sigma, are much smaller and to have the 50mm on the wide end is quite significant IMO. I feel most comfortable shooting portraits between 43-77 mm, 50-55 is absolutely terrific IMO. Given that both DA* and Sigma are IF, at closer distances they are slightly wider than 50mm....

so yes, I go for the smaller, slightly wider and shorter zoom..

This review might help: Fast Sports Zoom Lenses for Pentax | Sigma 70-200mm vs. Tamron 70-200mm vs. Pentax FA* 80-200mm F2.8

The Tamron is no worse optically than the DA*, and I think that you'll like the added reach. Portraiture is generally done in the 70-90mm range anyway, so both lenses cover that.

Since the Tamron uses conventional AF, I don't think the warranty should be a problem. The only real question here is whether or not you need the weather-sealing, and it's worth giving that up for the added reach. The Pentax also has slightly better handling (see the discussion in the review). Good luck!

Portraits sort of implies controlled circumstances that would render both WR and weight differences insignificant, really. However, you could get a Tamron 90 and have macro as well, plus some money left over :-)

If you can find one, you should give the Sigma 50-150mm f/2.8 a good look. It has the 50mm wide end like the 50-135mm, but with a little more reach. It's about the same size as the 50-135mm, but the HSM autofocus is much faster than the SDM of the 50-135mm. All three lenses produce excellent images.

I own the 50-150mm and love it.

You should read this entire thread:

https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/134848-convinc...-70-200mm.html

All three of the above-mention lenses were recently discussed. On page 4 I posted a bunch of sample images from my 50-150mm, and other people posted images from their lenses.

We've been chewing this over on a few threads. Ah, portraits! According to more than a few recommendations, good focal lengths for studio portraiture range from 35mm for full-body to 135mm for voyeur facials. Some people like longer, some shorter -- and guess what, there don't seem to be any good fast 35-135's around. Bother. IMHO a 70-200 is just too long, unless you and/or your subjects are anthrophobic. So I guess a 50-150/2.8 is the closest available. It would require a larger studio space than does a shorter lens.

70-200 is a great length for events, like indoor sports or weddings but awful long for portraits. On the other hand I just passed up a used 50-135 because I didn't want an out of warranty lens that had known SDM problems. I'm looking for a Sigma 50-150 myself. For now, I'm using my FA 100 macro for portraits and covering theater.

Phooey that just made the decision more difficult........I guess I should have said outdoor portraits...the 28-70 does fine in my limited studio area but its the outdoor stuff where I am finding I need the extra length. I have a feeling the tamron being the lighter of the 200mm lenses may be the one. It is really difficult to choose as I cant physically handle any of them. I am reluctant to purchase the DA and find it has problems as that would involve too many hassles working with an O/S purchase
and the sigma 50-150 seems to be about as findable as rocking horse poo......especially in OZ!
Prices seem to be roughly the same for all of them.
cheers

Gentlemen. If the offer is still on you can find the Sigma 50-150/2.8 HSM in Pentax mount at Ffordes (Scotland) for an amazing 400 GBP. If you want it shipped outside the UK then deduct another 17% VAT (old rate - old stock I guess) and just add on your DHL fee. Bloody fantastic price !

This guy gave me great service : Steve Byford <steve.byford@ffordes.com> and if you mention that Kevin in China gave you the link then maybe I'll get VIP treatment next time I buy from them I have no connection to Ffordes whatsoever and am not on any sort of commission !

I haven't received my lense yet as it was shipped to HK for a friend to bring into China (so I save the $200 import tax) ! I should get my grubby paws on it later this week !

I havent used any of the lenses mentioned in this thread but i have read into them alot,
if id have to choose, i would go for the Sigma 50-150 (if you can get a hold of one)
It has more range than the DA* plus it has sigma's HSM which is alot faster.
And its a lot smaller than the Tammy 70-200 and focus's faster than that too, its focal range is wider but not as long.

In summary the focal range of 50-150 is alot more appealing than 50-135 or 70-200 for portraits too, plus its smaller than the Tammy and its has the fastest focus of those 3, the 50-150 is the one i would pick.

One more vote for ffordes. I've bought from them on several occasions and was always very happy with the service they provide!

da*50-135.
70-200 will be too much overlapping of focal range.
100-300 will be better, or low cost options like 120-400 or bigma.

I have participated in dragon boat racing here in sydney for the last three years. We were nsw corporate games champions in 2009 and runners up in 2010. Also raced in darling harbor for chinese new year and came third in 2009 and 2010. This year we had bad
Luck at darling harbor our lead paddler broke his paddle in the second heat so were relegated to the b finals but still managed to clock the second best time of all the crews in both a and b finals. What is more one of or crew members works for Pentax
