I'm thinking of getting Sigma 28mm (or 24mm) f1.8 EX DG for my Canon EOS-300D. Do any one experience this lens? The main purpose of getting this lens is to take wider angle shot (than the current lens I have) and is also to take macro shots.

you're not gonna get very wide with either of those, the 28mm will essentially become a 44mm lens on yer 300D.

To get a 28mm eqiv, you'd have to get something like the 16-35, 17-40, 12-24 etc etc.

Yeah, I knew that. At least it's wider than the current 2 lens I have (50mm~, and 70mm~). I'm drooling on its F1.8. But wondering what its performance is. Thanks.

CDM,

At the wider angle, you can also shoot at a much lower shutter speed. Hence, the aperture of F1.8 may not be that attractive depending on your requirements. Most of the time, I can shoot with 1/15 seconds when using the 16 mm end of my wide angle lens.

You might find the 19-35 mm or 20 to 35 mm lenses useful for it's price. And as pointed out by Lisa, factor in the 1.6 X magnification.

Cheers,

tony - the good thing about that site, is that the majority of people on there KNOW what they're talking about. A significant portion of the members are professional or advanced amateur photographers.

Places like dpreview, and also epinions can be at times a little questionable in terms of product ratings, and real experiences.

Thanks for the valuable advices. I did checked that website (FM), and found the opinions about the lens in two extremes, some said wow, while some said big no. I surveyed some other websites, and there are reports about autofocus faliure of the lens on some Canon cameras. Don't whether Canon solve that prob yet. Anyway, think I'll reconsider this.

its not canon that has the problem - its the actual lens - a friend of mine got one of the sigma 180 macros for her 10d, and the camera kept giving errors. she sent the lens to sigma, who rechipped it for her at no cost - and it worked.

Lisa, thanks for the very useful informations.

I agreed with Benny. Fast lens isn't really important in wide angle unless you really plan to shoot in untra low light condition.

For DSLR, something in the wide range of 16mm - 20mm will be a nice combo. :)

If you want a WA lens, I'd look at the canon 17-40 f/4L, sigma 12-24 EX, tamron 17-35 f/2.8-4... you could always look at the 20mm primes as well...but that will put you into regular wide angle range with your 300d. I'm still not sure what I'm going to use for WA... either a specialized lens like the sigma 12-24 or the new canon 10-22mm...or just getting a canon 17-40 (more versitile).

the 10-22mm canon is more expensive than the EX 12-24 sigma ;)

Not by a lot...I think you can preorder the canon 10-22 from Dell for about $650 with some inventive coupon use ;) I'm just not sure how much I'd use such a lens...it's be AWESOME for wide angle landscape use...but other than that and architecture, what use would it be? That's why I'm almost decided on getting the Canon 17-40 f/4L... it's not ultra wide on my rebel, but it can also be used as an everyday lens (and I'd possibly sell my tamron 28-75 and just use a 50mm f/1.8 to fill the gap between 40 and 70mm).

Uhh, I know a heck of alot of people that use the 12-24 for all kinds of things - I use it for portraiture work, especially for group shots.

The Canon EF-S 10-22mm can only mount on a 300D and 20D (at time of writing). This translate to a effective focal length of 16 - 35 mm with the 1.6 X magnification effect. Incidentally, the lens contruction is also based on the Canon EF 16-36 mm F2.8 L lens.

Not withstanding the full frame Digital SLR cameras, the widest you can go at the moment will be the 12 mm with 1.3 X magnification, giving you 15.6 mm.

Right now I have Canon EFS 18-55mm/macro (came with the camera), and a Sigma 75-300mm/macro, both are with aperture 5.6. Sometimes it's not enough for the F5.6 when use these 2 lens for aquatic photography, especially the macro range. That's why I was thinking those F1.8 lens.

If it's specifically for aquatic photography, and for fish photography, a Tamron 90mm F2.8 macro is worth the consideration. The 24mm would be too wide. Probably good only for tank pictures, which you can already do with the current 18-55 mm. And if the budget allows, a flash.

Thanks benny. I'll do a little study on the Tamaron 90mm F2.8 macro. I have to check if it's compatible with the Canon Rebel. Some lens seem to have some focus prob when used on Rebel.

Quite a few of my friends are using this with the Canon 300D as an alternative to the Canon EF 100 mm F2.8 macro. No problems and tack sharp.

This above site will prove to be an interesting read. Especially for those who always believe that Canan lenses are above third party options.

No doubt the Tamaron 90mm is one of the better macro lens around. I have this lens previously and I love it! I am currently looking into the newer Di version.
