I am indeed going to Tetons, Yellowstone as some of the other posters mentioned in their posts. I've come to realize that the super long lenses like the Soligor are too limiting for my use. Too long/heavy. To much of a "one trick pony" - too long for many things. I don't see birding and wildlife photography as a major interest of mine for now, nor is there opportunity to use such a lens much living in the city.
Still not sure I'm willing to put down money (albeit not much) for a mirror lens given their reputation.
I decided that there may be very little opportunity for using a super telephoto, but a lot of opportunity for using a more versatile, shorter lens.
Therefore I think that I'll get Tamron adaptall Sp 60-300. +/- teleconverter. It seems to be a very well thought of lens even by comparison to modern lenses. It's cheap. I think I'll get a lot of use out of the shorter end of it's range too.
I have always been leery of TC, but the Tamron seems to get fair reviews (the 2x "01F") so for the price it may be good to have in case he need arises.
Are there other TC I should be considering? My only reservation is that it'd only be useful on adaptall lenses (which is also a plus in that I wouldn't have to use a separate adapter). I've got a Soligor 2x, but I think it's not considered very good.
Although I also have a Nikon D3100, I think I will try to adapt this lens to my Lumix GH3, as it seems to be a more capable camera and more importantly because I don't think lower end cameras like the D3100 will meter using adapted, older glass.
Thanks so much.
I have the Adaptall 60-300mm and a 01F teleconverter. The converter is also great on the Adaptall 90mm macro, in case you are thinking of that in future, and on the 500mm mirror lens, and it is the best converter I have used.
To be honest, I rarely use the 01F on the 60-300mm zoom. The lens is razor-sharp at 300mm, especially if you can stop down to f8 or f11.
With modern high-resolution sensors (above about 13MP), I would rather use the lens at 300mm and then crop the image. That way you do not introduce extra layers of glass and extra weight+length, you do not need to increase ISO to be able to handhold, you can keep in the mid-apertures, and you are less subject to motion effects.
