Not true, you don't have to pay for the calibration service at Sigma. I have bought all my Sigma lenses overseas and I got them all calibrated at the Sigma Service Center in Singapore for free. They didn't even ask for any proof of purchase or warranty cards. I even asked and they confirmed they...

Yes, definitely the 17-55mm is a faster lens, and it's of course a bit better in low-light conditions. But aperture is not everything, I find that the range of the 18-85mm outweighs the disadvantage of having a smaller aperture. IQ wise I'll rate them about equal - they're both as tack sharp as...

The Sigma 20mm f1.8 is not a very good lens, read some reviews online and you'll see what I mean. The Sigma 30mm f1.4 is an excellent alternative and it's what is always in front of my EOS 7D when it comes to indoor and/or low-light conditions without flash. Highly recommended! Be aware though...

Neither the 17-85mm nor the 18-135mm is really an "upgrade" from your 18-55mm, as long as you have the IS version of that lens. The only "upgrade" is the slightly longer reach, but as far as the IQ goes your 18-55mm is at least as good as those two. if longer reach is what you want you'll be...

Read what he wrote carefully. It will *take* a 2x TC it just won't *perform* very good. I've tried the same combo and I'll have to agree with that.

Why sell it off even if Canon launches a new version of this lens? The quality of this superb lens will not be affected whatsoever even if Canon launch a new version of it, and your pictures will still be as good! So why this obsession with having the latest model at all times? I say buy the...

The best fisheye lens for any crop camera is this lens from sigma: http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3337&navigator=6 - period! But be very sure that fisheye is really what you want because fisheye is... well.... fisheye :D

The way I see it you have been given mostly bad advices so far. What you need depends (of course) on what you wanna shoot. You said further down that you prefer to shoot landscapes and "macro stuff. Well then you definitely do not need a "superzoom" like the Canon EF-S 18-200mm for that, as a...

Man you're cracking me up. I suggest getting some red rubber bands to tie around your lenses too, that'll make them "L" grade. You'll be taking pictures like a pro in no time :bsmilie:

Yes it will still be big - but it will be less obvious what it contains. So the next time I'm in Rome I'll just find one of those guys carrying a big red Canon branded Crumpler bag and just stay reasonable close to him and my own gear, carried in a less obvious but although big bag, will be safe...

Be aware that a 50mm lens will *not* give you what you refer to as "human-eye view" on a 1.6x crop camera like yours, only a full-format camera. The closest thing on a 1.6x crop sensor would be a 30mm lens. I have the Sigma 30mm f1.4 and I'm pretty happy with it, but it's not as brilliantly...

The problem with this and similar bags is that it has "Steal me - I contain really expensive photographic gear" all written over it. While this might be such a big problem in Singapore (actually theft is not that uncommon here either) it will be in most cities overseas. And behing red - it makes...

Everyone should avoid those "chopper" photo shops Sim Lim, both locals and non-locals. Except Orient Photo on the sixth floor, thats is an excellent store with friendly staff, reasonable prices and they won't try to trick you to make a few bucks extra. I find that even Alan Photo in Sim Lim...

Hmm that does not sound right at all, that 5200 mAh rating *must* be bogus. The original Canon BP-511A is rated at 1100 mAh. I've seen 3rd party batteries claiming a rating of 1200 mAh, 1400 mAh, 1600 mAh and even 2000 mAh. And that sounds plausible, except maybe the one claiming 2000 mAh...

You can buy these on ebay for a few dollars. THis is an example of an adapter: http://cgi.ebay.com.sg/HDMI-F-TO-MINI-HDMI-ADAPTER-FOR-HDTV-LCD-DC-New_W0QQitemZ370168489819QQcmdZViewItemQQptZPCA_Cables_Adapters?hash=item370168489819&_trksid=p3286.c0.m14&_trkparms=66%3A2|65%3A2|39%3A1|240%3A1318...
