Now being the poor " old photographer " it precludes me from running out and purchasing the latest 300 mm Olympus f -2.8 , with a $ 6000 price tag :-(
|Olympus AF 300 (600mm) 4/3 lens $ 6000 !|
Added to my collection recently is a cool Bausch & Lomb 800 mm, spotted locally on Craigslist. In its original box as new the previous owners father was given this as a gift in the 90's and it became a shelf space taker.
|B&L 800 mm|
It does double duty as a cool star gazing / field scope, but came equipped with a " T " mount camera adapter.
Will this lens do everything its $6000 cousin does ? No it will not, no auto focus, no aperture adjustment .... but it will get the job done 70 ~ 90 % of the time when the subject is far off, and cost about the same a dinner for two these days.
