Re: Lenses longer than 600mm
I've just bought a Russian MTO 1100mm f10.5 mirror lens. Compared to a 300-800mm EX "Sigmonster" its tiny at only 10 1/2 inches long but it is quite fat at 5 1/4" diameter and it weighs about 3.2kg (7.04lb).
Now I would'nt normally consider buying a mirror lens at all but as this was going cheap on ebay and it was an 1100mm lens after all so I thought, why not?... I got it for just £65 inc the postage!
Anyway after only a few minutes of testing it was clear my money had been well spent as it was far, far better than I had expected it to be and it totally outperformed my sharp Enna Tele-Ennalyt 400mm f4.5 fitted with a 3x teleconverter to give 1200mm.
Here are a couple of shots of a section of a wooden Telephone pole taken from about 30m (100 feet) as a comparsion:
First is the Enna 400mm +3x teleconverter (1200mm FL): (Note: If you click on the pics you can see the originals)
And now the MTO 1100mm:
I dont know about you, but I was impressed!
I took it out with me the next day down to Bedfont Lakes Country Park and snapped this juvenile Tern standing in the shallow water at the edge of one of the lakes, about 10m (30 feet) away:
OK, I know its not exactly fantastically sharp but this lens is rated at only 28 lines/mm resolution in the center of field so I am sure you will agree its not bad considering.
