Canon primes: 50mm vs 85mm

**ret** · 10-24-2008, 03:33 PM

I am considering getting one of these primes

1. EF 85mm F1.8 USM
2. EF 50mm F1.4 USM

they both are in the same price range and I have the budget for one. I want one that will give me a better background blur, sharpness and general photography experience

and there is also this 50mm 1.8, which is pretty cheap for a prime. would like to know how its rated, along with those two lenses above?

ofc, I m highly impressed by the 135mm F2 L USM prime but I don't think I have the budget for it at the moment

The cheap 1.8 50mm is built horribly but is generally regarded as hugely good value for money. The 1.4 50mm is better built, a little better optically and has a better bokeh, so if you want to spend the money, that lens will probably be better in the long run.

So between the 85 and the 50, which focal length is better for you? The 85 is probably a better portrait lens, the 50 probably better for general purpose things.

i have the 17-85mm lens so I shot for a while at both 50 and 85 and i seemed to shoot at 50mm more .... but will take a few more shots to see how it goes

my main reasons for going for the primes would be for low-light shooting and getting bokeh

I'm going to grab the cheapie at some point for exactly the same reasons - but if the 1.4 is in your budget, it's a better lens, from the research I've done (I don't have either).

50mm 1.8 sounds like a good idea as you can test drive it

50mm appears to be the good one to start with on a crop sensor, on a full frame, i guess it would be b/w 85mm and 135mm

btw, is it a good idea to get a 50mm mark 1 than a new 50mm mark 11? .... i know that mark 1 comes with a metal mount, while mark 2 doesn't but is there a difference in optical quality b/w the two? .... in short which one is better

thanks that was informative. optically they are similar according to that review .... there is a buyer selling the mk1 for about the same price of a new mk11 so was wondering what should i go for

a new lens with warranty or an old one to get some exclusiveness
