What do I have? Let's see, this list has been accumulated over several years, and I'm luckily done now. There isn't a lens I would like to buy any more.
Sigma 12-24 EX - The first version, I was just curious about how wide this one is. The answer, it is wide. Bought this one used for half the price.
Canon EF 24-70/2.8L - Work horse zoom that I don't use as much now as I did a year ago. I'm pretty satisfied on this lens, and use it mainly on daylight time or at work. Surprisingly good at macro too.
Canon EF 28/1.8 - When Autumns get dark, this one will get more usage.
Sigma 28-300 - Bought several years ago in Hong Kong. I haven't used this one for ages, though it is still on shelves.
Canon EF 50/1.4 - One of the oldest lenses I have, works pretty well up to F/2.0, but has somewhat lackluster autofocus. Will probably see more usage in the autumn as I tend to travel with a bicycle.
Canon EF 50/1.0L - Not a typo either. This certainly is an art lens, that lives in dark or in shallow depth of field photography. I'm actually pretty happy about the performance of this thing, at F/1.4 it is certainly better than the 50/1.4 which is what I hoped for.
Canon EF 85/1.8 - I was mainly curious about this focal length, and bought one used. Pretty good for what it is, and still retains a good aperture for dark autumn time.
Canon EF 70-200/4.0L - Very good outdoor lens for event photography, good for pretty much everything which requires slightly longer photographing distances, though is limited for day light hours without a tripod.
Sigma 120-400/4.5-5.6 - Actually surprisingly good for the price. Relatively good macro capabilities too, while AF isn't as good as in 70-200. I was curious about what could lie in the telephotography and wanted a tool that could be used to test it with a reasonable price. I got that one down, but this one needs a lot of light too.
