Love the bit of excess on his lower lip....

How did you get from 500mm with a 2x converter to 2000mm? The crop factor
of the Olympus gets you to 2000mm?

Back on topic... some of these older lenses we have kicking around get new
use by melding them with digi-cameras.
I have a Tamron 300 F2.8 that I lusted over for years. Finally got one (
and that was many years ago) and used it a few times, then put in the back
of a closet and forgot about it. It has come out several times lately,
either with the D7100 ( Auto Diaphragm is REALLY nice to have) or with the
A7.
I never could nor will I ever be able to actually justify the purchase of a
450 F2.8 lens..... but there it is...in its glory, on the D7100.

Monopods are great.... 2 less feet to trip on.....

I've been experimenting with using a bit of "Frankenlens"... a 500/8 Reflex
Nikkor and my old Leitz 2x converter on the Olympus E-M1.

On a monopod.

Because this is an f16 combination, ISO 3200 is requried, even in broad
daylight. (At least on today's broad daylight, as we cannot see the sun,
for smoke from nearby forest fires.)

This combination is only possible because a previous owner had the Nikkor
converted to a Leica "R" mount!

This shot is of a Yellow Bellied Marmot, about 2o to 22 feet away from me.
Uncropped.

Resolution is not bad, with the 500 alone, but I think it suffers with the
2x. OTOH, how else do you get a 2000mm eFL?

The experiment is here.
