二楼太多了我复制一下4 elements, no coatings (that I know of), and a sweet round aperture. This lens is truly graceful, with minimal glass between the scene and the camera.
Smooth focus, even for a Takumar. Good bokeh at any aperture. Dynamite for longer range portraits.
No detents on the aperture ring allows perfect tuning of DOF. Very handy!
This one is not quite as surgically precise as my 200mm f4, but in my honest opinion gives a deeper and more dynamic look to most images.
Despite the lack of super coatings, it works very well in extreme sunlight as long as you use the hood. Colours seem very natural and balanced.
The Takumar 200mm f3.5 is a bit on the big side, but balances nicely in the hand and makes for a nice steady shot once a camera is stuck to the back of it.
Hard to rate against modern glass because it's just so different, but for dynamic images and user joy, it gets a solid 9 out of 10 from me. If you see one for a good price, grab it. It's a really fun lens.
