Sigma 18-50mm F/2.8 EX DC MACRO

El Duderino · 8th of June 2007 (Fri)

Just got this lens today and had to take some test shots. Nothing too exciting around here, but I thought I'd share. I got this as an upgrade from the kit lens. I hope it was a good decision.

These are straight out of the camera, just resized. All three of these were shot with an aperture of f/4 too:

Do they look OK?

I think I see a touch of CA on the white flower petals. I'd like to see some more formal tests though, like the old brick wall test and 100% crops. The bokeh on the first two are a bit harsh for me, but I don't think any of the normal zooms for cropped bodies have good bokeh.

I recently saw and handled it and it seems to feel better than the Tamron and the higher magnification ratio is nice to have as well I bet.

those look okay to my untrained eye. how about a few wide open

look awesome! looks about like the non macro. but yes, wide open! and mention where you used the macro, just to see how good it is.

El Duderino · 8th of June 2007 (Fri)

Thanks for the feedback so far, everyone. I'll do some more shots tomorrow.

This lens has a similar "tone" compared to my Sigma 70-300mm APO. On bright days, the photos kind of turn out white. I don't know how to explain it. Maybe it's CA?

Probably need to send a PM to Mike ("In2Photos") and ask him to start a new link to this thread in the archive called "18-50mm F2.8 EX DC Macro" (to discriminate from the non-macro version).

Alright, I've never done a 100% crop before. I zoomed in with Photoshop until it said 100% at the bottom of the image. Looks about right to me. No editing done on this one.

f/8, 1/400:

Tony-S · 8th of June 2007 (Fri)

In Photoshop, click on the "crop" icon and set to fixed size of 800 px by 800 px. This will give you a square of maximum size for the forum at 100% crop. Copy and paste this into a new document and save for the forum (i.e., correct size).

Tee Why · 8th of June 2007 (Fri)

Looks pretty good to me.
The photos looking white may be overexposure. CA is more purple fringes seen around a high contrast area, like the edges of the white petals. These are small shots, so I'm not sure if it's CA or not.

Here are a few more uninteresting photos that I took to test it out:

_aravena · 10th of June 2007 (Sun)

I noticed that with mine that the result was similar to the 70-300 APO but not in all conditions. I'd have to look through to see, but still, i won't get rid of mine.

shot with the fly looks good. Have fun with the lens.

turbodude · 11th of June 2007 (Mon)

Nice i realy think i am gonna get this one.

goatee · 11th of June 2007 (Mon)

These look great! I had the old non-macro version, and was very happy with it (just wanted a longer, and not so wide lens).

To be honest, I wouldn't even bother with things like shooting brick walls straight on - I never shoot things like that, so I'll zoom right in to make sure that the lens is focussing correctly, but other than that, leave 'lens tests' to people who like to measurebate

Anyone shoot this lens on the new MKIII and if so did it work well? I am looking at getting this lens.
