Sigma 24mm f1.8 EX DG Aspherical Macro

24_f1_8_1_
Review Date: Feb 22, 2006 Recommend? no | Price paid: $320.00 | Rating: 1 

 
Pros: None from my persepctive. Might be fine for landscape photography, but the lens was useless to me.
Cons:
Exposure latitude at the high end was awful in low light --detail was completely blown out. Colors off, and not very sharp either.

This lens was a big disappointment. I returned it and lost $30 in shipping costs.

I purchased it mainly for concert photography, shooting bands under poor lighting conditions. I have a 20D.

After using the lens for one concert shoot, with very disappointing results, I did an clinical experiment in better light to compare it with my $80 Canon 50 mm 1.8, in terms of exposure latitude.

Sure enough, the cheap Canon lens performed SIGNIFICANTLY better in terms of the detail in areas under direct light. With the sigma lens, much more detail was blown out.

These problems were present under well-lit conditions, but were exacerbated under poor lighting, which for me was the point of getting such a fast lens.

Sharpness was lacking as well, and the focus performance seemed to be inconsistent, though I would have to do further testing to confirm this.

I'm going to save up until I can afford the Canon 24 mm 1.4mm, and until then I will do without. I cannot recommend this lens, even at a quarter the price of the Canon lens.
