Pentax vs. Tamron lens

Hi, all I have a dilemma. I was all ready to pull the trigger on the Tamron 17-70 f2.8, when I saw an amazing deal on the Pentax super wide tele smcp-da* 16-50mm, f2.8 ed al (if). It was originally $1,029, but Selling from B&H for $749. What should a Pentaxian do? Need a quick answer. Thanks, all

Hi Gerrys,

I have been looking at prices for this lens for quite a while and the $749 price has been the going street price for some time. It is a significant markdown from the list price but is not really an exceptional deal imo. I have borrowed this lens in the past and really loved the images that it gave me.

Cheers

From the images I have seen the 16-50 produces better quality photos (but not by a big margin) and you save $ with the 17-70. Although $749 is good for a brand new 16-50 I would personally get the 17-70 and with the money you save you can get another used lens so you have to ask yourself, do you want a little better IQ or save $ ?

Not certain what lens you are looking at from the Tamron side. Is it the Tamron 17-50 f2.8 lens? If so, that is a very nice lens and reasonably priced in comparison to the DA *16-50. Seems like the Tamron lists for somewhere around 450, while the Pentax sells for about 750 right now.

I own the Pentax 16-50 and the benefits it has are weather sealing, one mm wider. It also has SDM. I don't know whether to put that under a pro or a con. It is silent, but probably is more prone to failure than screw driven lenses are. The Tamron probably is a little prone to front focus/back focus issues, but should be easily fixable if you have a body that allows adjustment.

I have seen some awfully good photos from both and am very pleased with the Pentax DA *. I have used it in a lot of pretty poor weather and so I wouldn't want to lose the weather sealing, but only you can tell what is most important to you.

By the way, if you are looking at the Tamron 17-50 f2.8, check out Prodigital 2000. They have it listed for 370 right now, a pretty amazing deal IMHO.

Thanks, all. I decided to go with the Tammy 2.8. The Pentax is much heavier than the Tammy and from most of the reviews that I have read, it seems that is the way to go. Got a great price from B&H, and with the Tamron rebate, it cost $414
