That would be an idea.
Originally posted by Shamwow The thought of carrying around a 2 lbs. lens to family functions sounds brutal. I'd rather have a DA40mm on the camera and a DA21mm in my pocket. Also, speed isn't the only determinant of price. Otherwise, the DA40mm f/2.8 would be cheaper than the DA50mm f/1.8 and DA35mm f/2.4.
That's completely correct.
Originally posted by Shamwow I don't often have a need for both fast and wide, usually just one or the other. Shooting groups of people indoors at f/1.4 or f/1.8 doesn't always produce enough depth of field. The Sigma 30mm f/1.4 can be had at a reasonable price for those few occasions you would need it.
You dont have to shoot a group at 1.8. You can always stop down. However, if you have a 16-45.. You're stuck with 4.0 automatically boosting to ISO 3200 most of the time

I like pixel peeping. I know, is a curse... :P
I know pentax primes are a league of their own. I am not comparing the 18-35 directly to primes. I am saying that in my case I couldn't find a fast prime that suited my needs. after all i would need about 2 primes minimum to get the versatility of this lens. That, and that you add the fact that you need to be changing from lens to lens. (assuming you buy a 20 or 24 plus a 35)
There's a lot more to like about a lens than just its aperture. I have not held the sigma in my hands yet let alone shot with it. However, reading reviews I have learned that this lens is not just numbers, the lens seems to be doing a pretty good job everywhere. so...
about price... I used this as a baseline:
Price Watch post Doing google conversion is $680 CAD. I know, shipping, duties, etc etc... however, it gives you an idea of baseline.
