Sigma and Tamron Lenses on 50d

[notahonda]

Hi ALL!
I am intending to buy the canon 5d MK II and i was wandering if Tamron and Sigma make FULL FRAME lenses? As I would like to buy a lens that is 24-70mm f/2.8 ...however the canon lens is 2k ... however i have seen sigma 24-70mm lenses going for around 700-900 bux. Can anyone advise me how I would know if a particular TAMRON or SIGMA lens is full frame?

I know the canon range can be suggested by the L's series. I was thinking maybe TAMRON and SIGMA have a series of lenses that are full frame.

THANKS ALL!!!

Having used/owned all the items you mentioned, I think i can give a bit of insight into this question i have asked myself many times.

The Tamron 28-75mm vs Canon 24-70mmL on a crop body i.e. 40D/50D/1.6x

Both are sharp in the center (@ f9-11 the tarmon is sharper) but over all the Canon corners are slightly sharper. Hence there is little difference except the price and build.

The Tamron 28-75mm vs Canon 24-70mmL on a FF i.e. 1D3s, 5d, 5d2. 1.0x


The Tamron has lost its throne. as the Canon starts to show its true potential.
The very center is still sharp but as you look into the 2/3 - extreme edges of the photo. The Tamron is fuzzy and i mean really fuzzy. Even the "bokeh" has "halos" around them. I think at this point the FF takes full advantage of the larger sweet spot of the 24-70mm Where as the Tamron as no more to give :\

I am in the process of procuring back the Canon 24-70mm myself

That is definitely information worth noting...Thanks for that, how about the lens range? is there anything that Sigma or Tamron uses .. for example how canon has the L series... that will assist me to distinguish between a FF lens made for canon?

[ricktas]

Any sigma lens with a DG nomenclature is a full frame suitable lens

Any EF Mount lenses can be used on the FF.

the EX designation for Sigma is sort of equivalent to Canon L, as it designates a pro grade range of lenses with better build quality and optically superior ( but not always ) to their normal lenses. They also have EX lenses for cropped cameras.

you just have to look at the focal length of a lens to tell if its full frame or not, aftermarket lenses like the Sigma 28-70, 24-70, Tamron 28-75, Tokina 28-70, 28-80 are examples

whereas for their APSC equivalent they would be Sigma 18-50, Tamron 17-50, Canon 17-55, Tokina 16-50, Pentax 15-45, to name a few

Sigma EX lenses also generally have a 'gold ring' around the lens. Good way to visually see if its is an EX lens. But the DG designation says it is designed for 35mm (ie full frame)

and DC designation for APSC cameras
