Greatings from Québec !
I was very impressed by the photographies made with a 300 mm Borg DG 60 ED. Its conception seems to be very different than traditionnal telephotos.
Is there someone (birdwatcher, for example) who uses this lens and could share his feelings about it ? Is there one review somewhere on it ?

Greetings from Germany,
Telescopes are a cheap alternative if you are willing to live with its drawbacks. My own experiences are that in a lot of cases, the massive increase in focal length can compensate for a lack of sharpness. I owned an AF-S 80-200/2,8 and used it with a Kenko DG 1,4x TC, resulting in 280mm focal length. Even stopped down to f/8, the photos I got with a modified Bresser Messier 1000/102 simple achromat beat it multiple times. But usability is a different thing. I cannot imagine taking the achromat to the zoo, for example. Weighting 7kg, it is a hefty load and big as well, measuring over a meter. Tripod requirements are high, increasing the load further.
If you are interested, I can dig for some test shots with the telescope to give you an impression about the performance.
