Opinion Wanted: Sigma 28-70mm F2.8 or Tamron SP AF28-75mm F/2.8

kelvgoh · 12th November 2006

I just picked up a Sigma 70-300mm F4-5.6 APO DG MACRO for my Canon 350D. The lens was good albit a bit soft on the longer range. I was thinking of picking up a "replacement" for my Canon EF 28-80mm f/3.5-5 kit lens.

I was considering either the Sigma 28-70mm F2.8 EX DG or the Tamron SP AF28-75mm F/2.8 XR Di LD Aspherical (IF). I was told that Tamron was more established over this distance and that Sigma has stop producing the 28-70mm f/2.8 lens.

Does anyone have any experience with these lenses?

Cheers

if you searched through the forums, alot of the people here will pick the tamron?
here are 2 good places to start off with
http://www.the-digital-picture.com/
http://www.photozone.de/

btw, i think there is a sigma 24-70 f2.8-4 still being sold as well.

here is a pic shot with the Tamron, f2.8, 1/125 @ ISO1600, no flash..

I have the Tamron 28-75mm f2.8. Its a good lens.

ExplorerZ · 14th November 2006

tamron is very

provided you got a good copy.

kelvgoh · 14th November 2006

Ya bro, heard a lot about the build quality and poor QC. Well, I'll put it off till next year and hope they sort out the problem.

Cheers

I have the Tamron too.. you can't go wrong with that...
build wise it's acceptable for the price range, and the IQ is great! focusing is fast, though not the USM standard... but at around 600, u can't really complain...

This is one value-for-money lens.. but like what the others say - check that it's a good copy..
bring your camera along to test it, and if i'm not wrong within a week u still can exchange it if it's not up to standard...

kelvgoh · 16th November 2006

Thanks for the advice bro. Will certainly check it out 1st.

Cheers

I vote for the Tamron too

Nice and sharp

zcf · 16th November 2006

got Minolta version of Tamron 28-75mm, it's sharp from f/4. But 28mm is really not wide enough for 1.5X crop sensor.

FilterFunk · 16th November 2006

another point i noted is.. this is 1 of the most common lens being used at the motorshow other than the 17-40L and 50mm (of the various makes)

kelccm · 16th November 2006

Another happy Tamron 28-75mm f/2.8 owner here. It is my primary lens now.

Thanks for the advice bro. I would certainly get this lens soon, what with GST going up

That's a very interesting fact.

I know it'll be my primary lens as my current lens, an EF 28-80mm kit lens from my old EOS 500N has been my primary lens. I juz wanted to get a higher f/stop lens to cater for low light shots.

Thanks to all the bros for their valuable advice.

Cheers

both do not produce tack sharp images. get the canon 50mm f1.8 instead.

obviously deh. you are comparing prime vs zoom here. but frankly, the tamron 28-75mm is the best third party f/2.8 zoom out there. wips the sigma 24-70mm or their 28-70mm. get the tamron!

lol then why you buy the Sigma.

I've got this:
Tamron SP AF28-75mm F/2.8 XR Di LD Aspherical (IF)

Shooting at f2.8 seems to be very soft to me... Maybe it's just me that is the problem?

The f2.8 don't seem be useful to me IMO... I usually shoot at f4 instead to get the sharp pictures especially at 75mm... Also, it is not wide enough for me... I think the Nikon D70s kit lens will be better for me...

any sample at 75mm f2.8? Mine is also soft at 75mm f2.8. But sharp/soft is subjective. Best if you have a sample.

http://forums.clubsnap.org/showthrea...highlight=75mm

notice the text shots at 75mm f2.8, the contrast is quite lousy.
