Hi All
My budget is $3500 and I can not get 500mm f/4 or longer primes so looking for cheaper alternatives.
I am considering 300mm f/2.8 to be used with TCs (1.4x/ 2x) almost all the time....
But after hearing thoughts about importance of Prime w/o TC I was looking for other available options for the same price and came across Old Canon 500mm f/4.5 (Discontinued).
Now my question is what will be your pic and why?
Canon 300mm f/2.8L IS + 1.4X TC (420mm f/4) / 2X TC (600mm f/5.6)
Canon 500mm f/4.5
How much will you consider paying for the Old beauty(Canon 500mm f/4.5)?
Thanks
Canon 500mm f/4.5
500mm without IS is a pain. It really restricts you a lot. With a monopod at least, you can use maybe down to 1/400s shutter speed. Of course, you can plan to shoot with a tripod with a full gimbal head. Also, Canon no long services that lens anymore. Making repair for that lens would require savaging parts from another unit.
