Well I took the plunge and purchased the above screw mount lens. It is not super fast, and therefore not super heavy, but I was quite happy with the results. I didn't really know what to expect when I took it out for its first shooting. To be even more silly, I attached my Tamrom 1.4X convertor to it to get a nice 560mm. Seems to work pretty good, even with the tcon attached. I got a little bit of purple fringing on some shots, but if the light was right, there was no sign of any ca's. The bokeh is really nice too. On shooting at such a long length, it was surprisingly easy to get the shots in focus using this lens. Nice dampened focus ring. I'd highly recommend using one, if you're into wildlife shooting. Here's a few samples........cheers......Don.

Thanks Robar. Camera settings varied from 1/250-1/400 shutter speed. ISO at 400, f/5.6 or 8. I varied the aperture settings. Don't know which I used for these photos though, as it isn't recorded. But even at f/5.6, this lens is sharp. All shot on a tripod......cheers....Don

You mentioned colour fringing, I find all of my old MF lensesshow a little CA, even the very sharp primes. My AF lenses are relative cheapies (zooms)yet seem to have CA more under control, I guess it became a priority over lens speed. There seem to be very few affordable faster lenses now (like f4 constant aperture zooms) and lots of slower but betterCA controlled slow (f4.5-5.6) zooms.
