A prime lens is better than a zoom, only problem with a prime is that its fixed focus so you have to move rather than the lens to frame the subject, but the optic's are generally much better than a zoom. A zoom give you flexibility, a prime makes you think about the shot and how to compose it. 85mm f1.8 a great lens.

if you want to do portraits, the canon 85 1.8 is by all accounts an excellent lens and is a nice focal length to work with.

i have a sigma 85 1.4 and it too is a nice lens, great smooth bokeh and a good working distance between you and the subject.

i can't comment on the tamron, assuming it's a good lens i'd still go for the prime over the zoom simply because lenses f2 or faster have something magic about them... you get a pop that's very difficult to get from a 2.8 lens unless it's quite long (135mm or more really).

go for the prime, you won't regret it.
 
HMM the prime does sound good my only concern with it is, if its a nightmare to use as you have to move around more
 
well, it does depend on what you shoot and how fast it moves, if it's adults or older children then it wouldn't be much different to a zoom, obviously younger kids running around is going to be much more moving around.

but you have to balance it out, a 28-75 lens isn't going to give you a huge amount of usable portrait focal length anyway, but in any case it will be a compromise - with the zoom you get convenience, with the prime you get ultimate image quality, better bokeh, more dof control etc etc.

my kit bag comprises of 3 primes and 1 zoom. a prime is on my camera much of the time. i only tend to use the zoom when i'm going somewhere like a zoo or on holiday where i won't always have much scope for zooming with my feet or i don't want to carry too much kit.

personally, i don't find myself running around all that much - i have two young kids and even with a zoom you are moving around to get the best framing so i don't think that should really be a deciding factor unless you have limited mobility.

and if shooting portraits is going to be the main use of the lens, i don't think there are many who'd argue the 85 1.8 is a great lens and will do the job just dandy.

thanx for that i think i will go with the canon 1.8 prime as i guess i have the 18-135 which i can pull out when i need the good old zoom

It certainly isn't a nightmare to use. "Challenging" would be a better description as it simply means you have to think more about your composition, unless of course, space is severely restricted.

I have both and my first choice is normally the 85mm although the Tamron certainly is no slouch.

I'm sure you'll be happy with either lens :thumbs:
