I just came from Death Valley National Park, used only the DA21 lens and never thought of using any other lens. Carrying it does not feel like a chore especially on hikes.

Trust me, I understand the appeal of the Pentax pancake prime lenses (I have the DA 40 and DA 70 limiteds), including form factor and performance, but I am surprised when I read about how "big and heavy" the Tamron 17-50/2.8 is. I am curious what other owners think, but I find it pretty darn compact and not too heavy for what it offers (it is both smaller and lighter than the Tamron 28-75/2.8). And again, while I love my prime lenses, I cannot ignore the versatility that a zoom like the 17-50 or 28-75 brings to the table, so I'd likely go with the 17-50 vs. the DA 21. Can't go wrong though.

I've had both... sold the DA21 (though I may repurchase) and still have the 17-50. It's simply a fantastic lens at all focal lengths and it rarely leaves my K-7 these days.

edit: and I wouldn't call it big and heavy at all, except in relation to the DA Limiteds. :P

Although I love small primes, I think it's good to remember that one should not compare the size of lenses, but rather the size of camera + lens combos. Relatively, the size or weight saved is a lot less when the same body remains attached to the lenses.

I have the DA21 and several zooms in the range of the Tamron. I would and did get a quality zoom in that range before the prime. I use them with different bodies for different occasions. The DA 21 is great with the K-x, and my DA 17-70 lives on the K20d.

thanks guys for your replies. it's good to hear both lenses have served you all well. that, on the other hand, makes me oh-so-torn. yet again.

i am basically in the same boat, trying to figure out if i'd like my first real lens purchase for my k-x to be a nice prime or an upgraded zoom.

the recommendation to upgrade the zoom first, followed by a nice prime later makes a lot of sense.

the problem is, those primes have the cool/wow/"look ... shiny!"/snob factor in their favor.

what to do ... what to do.

i had pretty much decided on the da40. maybe i'll get the tamron zoom after all.

ackkkkkk!

Personally, I'd rather have the DA 18-55mm Al II or WR and the DA 21mm ltd than the Tam 17-50mm f2.8.

to sameagle: i would say, go for a prime. it really gives you a fresh perspective, and you will learn more about your own shooting style and the types of shot you like to take more. the first lens i bought was a M 50 f2 and i loved it, so i subsequently bought the FA 50mm f1.4.


this brings me about to my current setup. i use the DA18-250 and my 50 f1.4 all the time. these are my only lenses so far, and they serve me very, very well - except for in low light indoor situations. hence my decision to dig deeper into my already shallow student's wallet to get a low-light wide performer. does the DA21 fit better into the lenses i already have? i kind of feel that the tamron will make my fa50 slightly redundant..

Link doesn't work, but I'm curious as to why you'd prefer the 18-55 II over the 17-50.

There's an issue with the link tool. I'm not that impressed with the 17-50mm. I borrowed one for a while. Plus, he has the FA 50mm f1.4. I have the 21mm ltd and FA 50mm and the Tammy wouldn't get used. I no longer have the II kit lens, but I do have the Sigma 15-30mm that I traded my 20-40mm f2.8 for after getting the DA 21mm ltd. The kit lens II and WR are under rated in my opinion. The Tammy give f2.8 but that isn't blindingly faster than the DA 21mm.

Edit: To clarify, I didn't say I'd prefer the II over the Tammy, that I'd prefer to have the DA 21mm ltd and KEEP the 18-55mm II over the Tammy given I have the FA 50mm f1.4.

Gotcha. That's an understandable opinion.

However, in my estimation (and bear in mind, Tamron QC isn't fantastic, so maybe you handled a bad copy) the 17-50 is as good as a bag of primes in many respects. Sharpness is fantastic. Bokeh is nice. It's not too heavy, and it's not too big. Like I said, it rarely leaves my camera these days, despite the bevy of primes you can see in my sig.

Some recent walkabout snaps with it:

wow these are beautiful shots!

i guess now the question is, given that i have an FA 50f1.4, should i get the DA 21 to complement it, or get the Tamron which might replace it?

While I have the Tamron, I still have the 50/1.7 (traded my 50/1.4 for it) as well. The 50/1.7 serves its own purpose, though it perhaps gets less use than it would if I didn't have the zoom.

Don't get me wrong... the DA 21 is a fantastic lens and you'll love it if you get it. For my purposes, though, the 17-50 is a much better value buy.

with your current lens line-up, I think it won't work that well because of the focal lengths that are covered well by the Sigma 15-30, DA21, and FA50/1.4. for someone who doesn't have such lenses at such focal lengths, the 17-50/2.8 would be great, especially with a DA15 to go along with it. too bad we don't have the 11-16, darn Pentax.

edit: we have the same reason. except that on my part, it's the DA16-45. and I know how really good and sharp the 16-45 is. but having the DA12-24, K28/3.5, FA35/2 and 3 excellent fast 50mm lenses to cover the focal lengths, I just can't find a place for it in my lineup unless I sold those lenses and go zoom exclusively. anyway, I'm close to considering selling my WR kit lens. I got 2-3 weeks to decide whether to sell it or not.
