Thankyou in advance for the input.

I have been using a olympus C-730 for about 3 years now and have been spoiled by the 28-280 zoom. I sell sunset and beachscape prints with super saturated colors as well as local landmarks. I have decided on the Canon 20d but am not convinced I need strictly canon glass. My leanings are towards the Tokina 12-24 Sigma 24-70 f 2.8 and Sigma 70-200. Any Thoughts ?

Thankyou Keith:bye:

For the super-wide on the 20D you should really consider the EF-S 10-22mm, optically nothing else seems to come even close.

For the middle the Sigma 24-70 seems a good choice, though you should seriously consider the EF-S 17-85mm too.

I can't speak to the other two lenses in your selection, but I have the 70-200 and it is an outstanding lense. You'll be very happy with it.

Hi NHL,

Of course we all need a wide for our dSLRs and this looks really nice. The Canon goes for list price of around $800 US so what do you think this Sigma should market for? Just a guess unless you already know?

Thanks
dale

I own the Sigma 70-200 2.8, excellent lens... however the 24-70 isnt really what id consider a great lens. Firstly, there is no hsm (usm) so autofocus is noisey, however moderatly fast. The autofocus/manualfocus is activated by sliding the lens up which i thought was also strange. Im sure it takes good shots, but its just not what i think is the best value in the range. You would be much better off with a

18-55 EF-S,

50mm 1.8,
http://canon.com.au/products/visual/...50mmf18ii.html
Canon 24-85 USM, http://canon.com.au/products/visual/...mf3545usm.html

which are dirt cheap, and spend the extra money on a memorycard, flash or battery grip.

Also check the Tamron 11-18mm , its got a good feel to it, and its an SP (like L or EX).

Good luck with the purchase.

The 24-70 f/2.8 EX is of good value if you compare it optically against the cost of the EF 24-70 f/2.8L (also a full-frame)

If one 'needs' the f/2.8 for the APS-C then there's always: http://www.sigmaphoto.com/lenses/len...85&navigator=6

I have high hopes for this lens.

www.warehouseexpress.com sells the Canon @ £550 and lists the Sigma @ £340, so a very good saving.

The sigma is 1/2 stop slower and although the charts aren't unequivocal - I do think the Canon has an advantage at the wide end, even though the drop-off above 10mm is pretty sharp. At the tele end the Sigma seems to have the advantage. Stop the Canon down half a stop though and who knows?

Both lenses have good build quality and both have the fast motors.

I'd appreciate your thoughts on the MTF comparison.

At any rate the Sigma certainly has a large value-for-money lead, even if it's optically not quite as good. I've promised (myself) not to spend any more money on equipment this year, so we'll have plenty of examples and anecdotal evidence by the time I have to make a choice. :-)

Doesn't help Keith though ...

i don't know why everyone is so quick to dismiss the tokina 12-24 F4.0... it offers a constant f4.0 and compares optically with anything out there..
