In the market to pic up one of these two lenses. (Used) 70-200 is running about $500 and the 85 $3-400. Its going to be used with a 7D. Personally, I like the range of the 70-200 but would only be able to use it during the day with great lighting. On youtube there are a few videos showing how the 85 is better for portraits and such. At the moment, my only lenses are the Siggy 30, tokina 11-16 and the kit 18-55. I know the ranges of these two are different and both have different reasons for using them, but if you were me, would you go for the speed and sharpness (85 prime) or versatility and range on the 70-200?
Thank You.
What do you want them for?
The 85mm F1.8 does a very specific thing. The 70-200 F4L is a very versatile zoom. If you want thin depth of field and super sharpness, even wide open, the 85mm is your lens. It's usually $320 or so used, both on Amazon, KEH, and here on POTN. The 70-200 F4L, well, it's F4. It's not nearly as sharp at F4 as the 85mm is. Using it at 200mm, without IS, means you need higher shutter speeds, especially on a crop (7D). It has nice image quality, but when you compare it to a very sharp prime, you'll quickly see the difference. I say this as someone with both of these lenses. If I wanted to take pictures of a person, I'm not reaching for the 70-200 ever. I'm reaching for my 35mm F2 or 85mm F1.8 primes.
Very best,
