I like to take some of my Ebay photos closeup with a rather narrow DOF. The 45 would be good in some situations but a bit long for indoors not to mention I 'dhave to boost the ISO for handheld indoor shooting. My adapted 28/2 is pretty much the perfect length and is fast enough to use indoors as well as to give me the shallow DOF I want. Does the trick if I'm listing one item on Ebay, but when I'm taking 10 different shots of 10 different items MF becomes tedious. If I still had the 20 (returned because defective and will buy another soon) I might not be writing this thread, but truthfully I want something a longer. The Sigma 30 I currently use for the job is actually right around the right length, and does good in when the subject is close for a shallow DOF, but f2.8 is doesn't give me the background blur I want when I need to pull the camera back a few feet. Plus, a f1.8 lens would give me ISO800 instead of 1600. The lens I think would work best would be something in the middle of the 25 and 45, like a 35/1.8. The 25 would probably be the best available lens for the job, but I wish it were a bit longer and also, since I plan on always having the 20 and the 28/2, I'd hate to spend $300 on a 25 just for Ebay pics. In the following pic the first pair of shoes is the subject but I want the back ones to be a bit blurrier and didn't feel like popping on a longer lens just for the one shot. Sigma 30 @ f2.8: Subscribe to see EXIF info for this image (if available) With this pic I was @ f4 because I wanted both shoes to be in focus. But since the background is so far away, it looks fine. (In case if you're wondering, this shot was a 5-second shutter, a time span in the middle of which I quickly turned the lamp on and then off.)

When the subject is about the size of a camera lens 30mm @f2.8 does fine, but when there's a larger object, like an entire book and some of the background, it doesn't give me what I want as far as shallow DOF. Below is 50mm at what I believe is @f2.8. Love this shot. Subscribe to see EXIF info for this image (if available) Voigtlander could get me this. Or Nocticron, Or full frame. Or 35/1.8. C'mon Olympus!
