Since everyone seem to be comparing Tamron to this DA lim. I'm a big fan of Tamron lenses and use them alot (28-75, 70-300 VC). Best value for money in the whole industry imo (although Sigma still owns UWA and supertele). The point of this lens however is WR, DC, size, and build. People attach actual $$$ value to these and for some, this value justifies the extra cost of the DA 20-40
If you're skeptical about the value of "build", please try any takumar or any limited. It's so nice to use that you actually want to pick it up and shoot just for the heck of it. I never feel that way with my Tamron lenses. For paid work I really dont care about this, but for personal shooting I value it enough to still use Takumars.
Originally posted by RGlasel Actually Andi, there is something very comparable, with a few advantages of its own.
Lenovo ThinkPad X1 Carbon vs Apple MacBook Air Infographic It's off-topic, but having used several different brands of laptops for work and home since '97, there is nothing that compares to Lenovo for build quality. Of course, you have to prefer black over white and the X-1 Carbon won't run OSX (not a disadvantage in my mind).
My last off topic post I swear
After this I'll bring to PM.
I haven't read the specs of the X1 in detail, however I noticed the one compared is the old Mac Air. The newest Haswell has 13 hours battery life and on this front I have yet to find a comparable computer, but will be happy to be proven wrong. (Since the imac moved to IPS displays imo it has also been the best value AIO computer). As a disclaimer I'm actually still saving up for my own mac air, same as this DA lim
. My Nexus 4 have been quite satisfactory for computing on the go.
As much as I'd love to, I dont think I will be buying this lens anytime soon due to its price, myself
On the topic of weight and size, DA 40 is the only pentax lens I kept as It's the only one I can't replace in another mount, so for me at least, there is value attached to weight and size. If DA 40 is $1000 I doubt I would have owned it though.
