This is a very underrated lens. I got it for only € 25,- but it turned out to be very valuable lens for video. I use it a lot. It's sharp, contrasty, zooms butter smooth and is easy to operate due to the push-pull focus/zoom ring.
I use it with an EF 58mm lenshood wich fits perfectly and gives the lens a contemporary look.
There is no visible distortion at all focallengths wich is nice for architecture.
At 70mm it has an MOD of only 44 cm, in other focal lengths it's 1,5 mtr.
Pleasantly surprised at the quality of this older lens which can be found for about $40 or less online. Image quality is good and still slightly competitive with modern offerings. At f/4 the image quality does suffer a bit, but is still usable if needed. Didn't get the dreamy bokeh effect I was hoping for at f/4 here for me. Stop it down a few clicks and the image is pretty sharp and usable. Nifty macro focusing is actually pretty nice, but only available at the minimum focusing distance of 70mm, darn. Great starter zoom for folks trying to learn photography.
This lens covers the focal lengths of four fixed focal length lenses: 85mm, 100mm, 135mm and 200mm. Even though it has a zooming ratio of 3, it is still designed compact and lightweight. In spite of its short length, aberration correction is very good.
A high refraction lens prevents coma at the center focal length position and maintaining high resolution and contrast throughout zoom range. A single ring permits simultaneous zooming and focusing.
Macro focusing from infinity to 44cm is possible when the lens is set to 70mm. The 70-210mm zoom lens offers the brightness and high performance of an f/4 maximum aperture at an affordable price.
This lens withstood a drop of 5 feet onto pavement with no issues. Lens kept on working. I found that the colors were more subdued and less saturated than the 80-200mm F4L.
