My 2 cents. It's so big and cumbersome to the point of not wanting to use it.
Thanks for posting these. I thought that soft focus due to vibration would be a problem, but these images look crisp.
I guess MLU is a must, as are shutter speeds above 1/125 s?

Originally posted by desertscape Thanks. The helicoid is the variable tube for macro work. The 600 is a strange lens. Massive chromatic at f/4 but it calms down a lot by f/13. Technically it is afflicted by spherochromatism. Beyond f/13 it is quite sharp and the chromatic is near zero by f/22. I use it for birds, lightning and sunsets. For birds it does OK once you realize that shutter vib can really affect this lens. Here's a bird shot with the 600 + 2x converter, cropped.
Great ! Thank you. I just bought a 600mm and Iīm waiting to have it delivered. I havenīt used color or slide film in over 20 years, so chromatic aberration is less of a problem. I photograph mainly nature in B&W and want to work more with birds in that format. From what Iīve read, it seems more frustrating having to deal with a 12 m minimum focusing distance, then the other complications of this big piece of glass. I found a pair of outer bayonet rings in very bad shape and welded together by time and neglect. I hope to be able to fix and use them, as they seem to be very difficult to come by.
