Sigma 18-50mm F2.8 EX DC

18-50f28
Review Date: Mar 10, 2006 Recommend? yes | Price paid: $440.00 | Rating: 8 

 
Pros: Wide angle and speed, overal range, sharpness at f5.6 and up.
Cons:
a bit soft below f3.5 or 4. not as accurate in low light to focus as some of my other lenses (on my 300D)

This was my first 'good' lens. I bought it for the 2.8 aperture, 18mm wideness, and 50 length. The other lens I considred was the canon 17-40 4L. The Sigma won out for lower price, longer range, faster optics and the reviews I could find said it was favorable in optical quality to the canon.

After 10 months of use I feel middling about it - it is a bit soft below f4, so i try to never use it below 3.5 - tough, as this is the lens i use in low light (weddings, museums, indoors in general)

I like the color and contrast, speed of focus is acceptable, but a times it seems a bit off - not sure if that is the softness i see or i am just working in too low a light for good focus on my 300D.

I may replace this once I get my 30D - the 30D is supposed to kick in extra sensors for focsuing with 2.8 lenses - we'll see. I'm interested to see the new tamron 17-50 2.8 SP lens.

Price wise I got mine new of ebay for $440. About $80 more than I think it's worth.

Review Date: Mar 10, 2006 Recommend? yes | Price paid: $369.00 | Rating: 10 

 
Pros: Sharpness, low light focusing, range, value for the money, best lens in this class (range/speed combo), build, color and contrast
Cons:

I was using a sigma 18-50 2.8 EX as my walkaround and wanted more range. I considered the canon 28-135 IS and tried the Canon 17-85 IS and the Tarmon 24-135 SP - the tamron was $240 less than the 17-85, as sharp, as fast to focus and had more range, and at thelonger ranges is a shade faster. The 28-135 did not get the best reviews for image quality.

Afer 5 months with this lens, I love it. Great in the studio, good close up/macro lens and the range make it perfect for general walkround use. I have used it at a wedding and the low light focus is great - much better than the sigma 18-50 2.8.

Highly recomended.

Pros: Nice lens for the price. I got it instead of the kit lens for my digital rebel. Light weight, sharp.
Cons:
Slow (3.5 to 5.6) but that is accounted for in the price.

I bought this lens instead of the kit lens for my Digital Rebel. I had heard nothing all that great about the kit lens, and this was cheaper (kit lens about $100 w/ body this was $70). Also gave me a chance to try a Tamron lens. I also got the Canon 50mm 1.8.

I like this lens! Granted, I have little to compare it to, but my only complaint would be the bokeh is not as nice as the Canon 50mm 1.8 and it is not as fast a lens. It is light weight and covers a nice range.

I can supply pics if anyone is interested - I hesitate to put links here as they may change unexpectedly.

My plan was to get this lens now, and perhaps upgrade later and sell it off without losing much - I like it well enough I may very well have it for longer than I thought, opting for other accessories first.
