Hi guys,

I decided to up my budget to $600 for a walk around lens. What I need is a lens to replace the kit 18-55mm lens so that I can have longer range and shallow depth of field - wider angle lens would be nice.

At least I would like to have f/2.8, USM / HSMand anything above 55mm zoom. Can you guys help me pick out the ideal lens for $600? I dont mind Sigma or tamron brand since I have a sigma right now and it worked great!

some options:

Sigma 24-70mm f/2.8 EX DG ($439)
Tamron 28-75mm f/2.8 IF ($389)

Thanks!

You're on the right track. If you want f2.8 zoom, you can also look at the Sigma 18-50, 24-60, and 28-70 EX lenses. But the Sigma 24-70 and Tamron 28-75 are very good options as well. The Canon 17-85 has IS and USM but is somewhat slow not being an f2.8. Decisions, decisions...

thanks for the reply fstopjojo, I dont thin the sigma I am interested has USM in it and I'm wondering if it is a necessity if I ever had a chance to use this for events while travelling. Sometimes I take pictures of pets too and they like to run around.

hmmmmm, I'll take a look at that canon you mentioned.

I think you have listed your two main opitons.
Neither of those lenses lists USM/HSM as the focusing drive.
I have the Tamron 28-75 F2.8 xr di, and I find it is very good espeically for the price paid. :-)

Tokina also makes a 28-70 F2.8 and a 28-80 F2.8

I do not know anythng about them, they do not seem to be carried by any of the stores I frequent.

Canon also makes a 24-70 F2.8 usm L and a 28-70 F2.8 usm L, but the prices are way out of the range specified (2x-3x).

Hi Peter,

Thanks for your input, do you happen to have any examples of pictures using the Tamron 28-75?

Thanks!

You don't need fast focusing if you use the hyperfocal settings :idea:
Trouble is setting a zoom to the hyperfocal setting is very difficult :?

With the Hyperfocal setting on a prime lens, eveything from 1/3 in from the focus point to infinity is in acceptable focus.
Ie: say your 50mm lenses Hyperfocal setting at F11 is at 12-feet, then everything from 8-feet to infinity will be in focus. Great way to get really huge DOF, and not have to wait for the camera to find focus :-)

Trouble is modern zooms don't usually have the needed focus markings on their barrels to make use of this. Though it would be a fairly simple program to load into the camera since it already knows the focal length and the F-stop selected then have it do a table lookup and set the lens to the hyperfocal distance accordingly.
Kind of wonder why this feature has not shown up in the cameras :G

Yes I do have samples, I can't for the life of me remember my photobucket account
(old age setting in)

Thanks Peter! Looks like I'm sold to the tamron! the price @ bh photo is pretty good, less than the sigmas.

The reason it's less than the Sigma is because the later is a full-frame like the Canon EF 24-70 f/2.8 L, i.e. a lot more glass (and what you're paying for) in case you want to move up later

The other advantage is the 4mm at the 24mm setting make a 'huge' difference to the small extra 5mm gain at the long on the Tamron (which you can crop BTW and have the same effect)
- You can't create a wider FOV than what a lens can't see...:idea:



BTW beautiful pictures PeterP - lighting wise!

Both the Sigma and the Tamron are full frame, and neither has HSM/usm.
The Tamron 28-75 f2.8 XR Di is in their Di series (works with both 35mm and apc-c), not the Dii series which is aps-c only.

I do agree about the extra bit at the wide end, the 24mm gives you an effective 38.4mm lens on the Canon 1.6 crop cameras. the 28mm gives you a 44.8mm equivelent.
Neither is very wide, both bordering on the normal human FOV which is abound 45mm.
If you decide you really want something wider, the Sigma 12-24 is a nice bet, but there goes another 800$us or so.
Also both will work on a 5d :idea: :-) or 35mm (I still shoot a fair bit of slide film), unlike all the ef-s lenses.

Sigma is being discounted here at the moment, the new 120-300 F2.8 EX DG Hsm is being listed as 300$cdn off what I paid for it

The 12-24 is being discounted by 91.66 going for 825$us
The 24-70 F2.8 is being discounted by 58.33 going for 525$us
The 70-200 F2.8 is being discounted by 108.33 going for 975$us
The 120-300 F2.8 is being discounted by 249.99 going for 2250$us

The Tamron 28-75 F2.8 is listing at 500$us
The Canon 24-70 F2.8L is listing at 1417$us.

So right now there is only a 25$ difference between the Sigma and the Tamron, and the Canon is only 3x as much but it does have USM:blah:.

Grumble - the prices here are much higher than in the US - Grumble. :evil:
