Sigma 28mm f1.8 EX DG Aspherical Macro

Review Date: Oct 29, 2003 Recommend? no | Price paid: $245.00 | Rating: 4 

Pros: fast aperture of 1.8
my lens was not sharp at 1.8 and had serious focusing issues on my 10D

I really liked the concept of an f/ 1.8 macro 28mm because I expected to be able to do compelling compositions wide open and play with spacial realtionships, etc., as well as using it as a slightly short "normal" lens on my 10D. But the lens I had would not focus accurately at 1.8 or even stopped down.

After carefully testing with the yardstick at a 45-degree angle method, I found that this lens consistently focused significantly ahead of the focus point selected. I had read in some forums that there was a problem with the computer chip on some Canon bodies and that Sigma would "re-chip" these lenses. So I sent it back to Sigma to see if they could make it work with my camera.

It was returned two weeks later with a curt note stating "cannot change software in the lens." The next day I put it on eBay.

Since, I've purchased the Canon 17-40 f/4L and I couldn't be happier with it.

Canon Macro Ring Lite MR-14EX

Review Date: Oct 29, 2003 Recommend? yes | Price paid: $450.00 | Rating: 10 

Pros: ETTL with my 10D and G5 works beautifully; wireless IR remote using 550EX's is so automatic that I have a hard time "fooling" the metering; ability to set flash ratios gives great flexibility
I'd like it better if you could adjust ratios of remote flashes individually rather than having to "group" to an "A" and "B" channel, but there are several ways to work around this. When used with the G5 there is a hesitation between pressing the shutter release, the pre-flash, and actual exposure

I originally purchased this unit to use with the 50mm compact macro f/2.5, but have since used a good bit with my G5 plus for those down-in-the-dirt, low-angle macro shots that are easier with the flip-and-twist LCD than geting on my belly with an SLR. The MR-14X seems to work well with both cameras.

I've also used quite a bit with a hand-held 550EX slaved to be triggered by the MR-14 and this works just beautifully, opening up all kinds of possibilities that would not be available with just the on-camera ringlight. Here's an example:
