Okay, here's the deal. I am a retiree who likes photography as a hobby. I enjoy all types of photography, but my favorite is probably macro due mostly to the fact that the subjects either are very slow or don't move at all. I also enjoy landscapes, but my opportunities are limited. My two grand children occupy my interests in portrait photography. I have tried birding, but don't seem to have the patience necessary become good. To these ends I have a Canon nifty-fifty 1.8, a Canon 85 1.8, a Sigma 105 f2.8 macro without OS, a tamron 10-24, tamron 70-300, a couple of Sigma walk-arounds (17-70 and 18-250, both OS) and an older Sigma 170-500 f5.0-6.5. My question is that I have tripped and fallen into about $1,000 that I can use for the purchase of another lens to add to my repertoire. I am considering the Canon 100 f2.8 IS, but I would also like to include one of the Canon 70-200's (probably a used f4.0, either with or without IS).

Are there any recommendations from you guys. You all seem to be very astute when it comes to equipment needs evaluation. Thanks in advance for any responses.

You have eight lenses, ranging from 18mm to 500mm, and I'm betting you don't use all of them very often. You can sell one or more on ebay and put the money toward a high quality lens. When it comes to lenses, go for quality over quantity.

Sell some lens and buy a used 400L series prime lens.

I think you you have earned the right to a "L" series lens. These are Canons pro line of lenses. You won't regret getting one.
I have a 16-35 mm f/2.8L, a 24-105mm f/4L and a 70-200mm f/2.8L
By far my favorite is the 24-105. That is the one I would recommend but its just my opinion.
The 70-200 with a 2x teleconverter makes a pretty decent wildlife lens.

The Canon 100 mm 2.8 would be an excellent macro lens that would also serve as a good portrait lens.
