Yes
narrowed my search down to these too lens

mainly used for portrait,
ive read good reviews on the both
also NON VC on the tamron is the sharper one and said to be a cracking lens, and also very cheap

both are around the same price, but the tamron is cheaper at £220 new

im on DX d7000

do i buy them new or look for a 2nd hand model

The Sigma is terrible at f/2.8 read the reviews not bad from f/4 onwards though. The focal length will also be a bit weird on a crop camera.

I have had the Tamron, super lens for the money only upgraded from it as I had went full frame.
 
The Sigma seems to get mixed reviews on here, a bit of love and bit of hate, where as the Tamron seems to universally well regarded so I'd probably be gravitating to the Tamron out of those two. However, seeing as you say its for portraiture the Sigma's range makes more sense to me so I'm just wondering if you have considered the Tamron 28-75 2.8 as well, which seems to be very well regarded.

okay just actually looked at the a few more reviews on the sigma so its deffinately the tamron

but do i go for the VC or non VC, the reviews ive seen say the non VC is sharper?

and for the price ii guess its best buying it new as can be had for £220
 
Although not really aimed at DX users, I favoured the 28-75mm f/2.8 Tamron (compatible with both cropped and full-frame sensors). For portraits, especially on a cropped sensor, this lens covers a great focal range. I rarely need the wider end of a 17-50 so justified the decision that way. Your style of shooting may be different to mine though. :)
 
If going for the VC version just bear in mind that the VC mechanism is stupid. It takes about a second to engage (which makes it a poor choice for grab shots) ...having said that, at least it's there when you need it...

would like it to be quick as its mainly for childer so need fast focusing

the tamron 28-70mm is over double the price of the 17-50mm

i have a sigma 50-150 for the longer focal range
 
The newer tamron is fine with the VC, if you dont want to use it you can turn it off, but if you buy the older non VC its not there if you do need it.

I didn't suggest the new Tamron, I suggested the 28-75mm. The copy I had was a lot sharper than the longer length zooms I had across the same focal range.

The lens can be picked up for less than £200 in good used condition.

If you are using it for portraits I can't see the VC is going be much use to you. I'm not convinced there is any real optical difference these days, maybe just the early VC lenses.

ive seen a few of the sigma ones go for around £200 which is a good price im just unsure which of the 2 would be sharper with the best bokeh

The Tamron 28-75mm f2.8 is a better lens than the sigma 24-70mm f2.8 especially on a crop which eliminates the vignette and corner softness that the 28-75mm exhibts wide open on full frame, both can be had for around £200 second hand.

the tamron 17-50mm f2.8 either VC or non-VC is a great a walk about lens for crop sensor cameras but is not directly comparable to eith of the above given the vastly different focal lengths.

Only you can decide which range best suits, but for me if all you will be shooting is portraits I'd get a 28-75mm f2.8 especially if you have the wide end covered elsewhere.

It isn't. It will work on a cropper x1.5 the focal length so 42-112.
