Yes Steve we have a 5d and a 5dmkII that we really enjoy.
I have a 24-70 f2.8L that is nice and a 70-200 f2.8L that is very nice but now that we have the zooms covered I want to get back to enjoying primes for their lightness, brightness, convenience, and over all quality.
I intended to buy the 50mm 1.2L but went with the 35mm as it seems to be a great lens by any standards. The 50mm 1.2L seems to be equaled by the 50mm 1.8 once you are above 2.8 and so the 1.8 seems to be a FANTASTIC value for a very good lens.
I wasn't so much interested in the wide open aperture but now that I have it I'll exploit it.
I never had such nice lenses when I was young and hungry... so now it's just a real treat to have them and have such easy access to image processing.
My big
problem is that I want the 800mm and I realize that you should buy it when you are 21 because you'll want to use it every second you have on the planet to justify it's astronomical cost. It seems a pity that I'll probably not have one until I'm near the end. :-S. If that makes sense.
Luckily I am happy driving my old car and I am a cheap skate in many ways... so maybe just maybe I'll snap and do it before it is too late.
In the mean time I think the prime 35 will increase the fun factor of carrying a camera around to places where nice photos may be made.
all the best,
mike
