Ugh... Why are fast lenses so expensive... I don't have that kind of money to be spending on a lens... if I want to stay married that is... ;-)

yepThis was my thinking as well, there are many fast primes that I consider inexpensive lenses, where my definition of expensive is anything over 500$, really.
Canon 50 f1.8, f1.4
Sigma 50 f1.4
Canon 85 f1.8
Sigma 30 f1.4
and a bunch of others are all under or at the 500$ mark.
Fast lenses have bigger glass elements, which costs lots more to produce than smaller ones, especially in the area of optical corrections. That is the one sentence answer. Also since they cost more the makers stick even more features on them that also raises the price some since the percentage of increase is lower than to do that with cheaper slower lenses.Sterling Imagery wrote:

They are not expensive because the glass elements as still small. It costs about 100 times as much to grind and perfect the 6" diameter front element of a 600/4 than it does the 1" one of the Nifty 50. Everything in between is a percentage of that.BAK wrote:
What's "expensive" mean? And "fast"
The Canon 28mm f2.8, 35mm f2, 50mm f1.8, and 85mm f1.8 are fast, and -- at least compared to some other lenses -- not expensive.
And they will all give you great 12x18 prints using a current or recent Canon D-SLR.

You mean the 50/1.8 as the 50/1.4 is no bargain.Searching wrote:
how fast do you need.
Wow a real bargain. Let me know if you ever want to sell it. It could replace my Tokina AF 300/2.8.johnboy wrote:
I picked up a sigma 120-300 2.8 to shoot my girls soccer games for a grand. Not super cheap, but I consider it a rental as I dont think I will lose much when I resell after soccer life is over.
