Not sure what 'very long' means but I've used this Vivitar (Tokina) 70-210 AF lens on my GH2. The results are generally good although it tends to lose contrast in bright sunlight.
Crop vs teleconverter
I am using the Samyang 500mm for video. Picked up a used one for about $75. IMHO it provides good value for money. Image quality is good although one should not expect Canon/Sigma quality at this price point. This lens does not have image stabilization, so on windy days it is very hard to get steady images, even when used on a tripod.
It is about 15km to the trees and 380000 km to the moon. Lens MTO 1000mm, GH1, mjpeg timelapse.
And here is the jupiter and moon stills 100% crop. Click to enlarge.
Shot Yesterday on GH2 in ETC with 75-205mm Komine/Vivitar F3.8 @205mm f11-16 ISO400
Careful with mirror lenses, they have the notorious "doughnut" bokeh. Not really nice with a contrasty background.
Not much info on that guy, one 2 star review on amazon:

Rokinon also makes a mirrored lens, 300M F6.3:
I'm cheap as hell but still want some supertele for my wildlife photo/video aspirations...
I've stumbled upon this...what say ye? Are there any ancient, old tele lenses I can get on the cheap?
Barring the quirks with its Optical Stabilization system, the Sigma 120-300mm ƒ/2.8 DG OS HSM "S" lens is a fantastic piece of glass that features professional-level image quality, build quality and features at a price point that, at least at the time of this review, are not matched by any other competing lens manufacturer.
The new Sigma 120-300mm lens is the first "Sports" model in Sigma's new Global Vision line of lenses. This long telephoto zoom combines the flexibility of a zoom with the image quality and constant ƒ/2.8 aperture normally seen on higher-priced telephoto prime lenses. The addition of image stabilization (when it works) makes it a no-brainer for sports and action photographers that shoot in all sorts of environments and weather conditions. It's well-suited outdoors, for football or baseball season or indoors, courtside at a basketball game. Nature and wildlife photographers should take a look as well. The zoom really makes this a very versatile lens.

this is a old 1970s era Asanuma 80-220mm f3.5 .. shot on a GF2 - 440mm equivalent
Here is an EX24H screen grab of CM Night footage shot with at f/5.6 1/50 with a Canon 100-400m f/4.5-5.6 F
It's still my favorite telephoto zoom at the focal length.
The image is watermarked, but a ungraded PNG (so no lossy compression).
You can see it and the one with tonemapping at http://perlichtman.com/pasdenapulse/wordpress/2012/05/06/super-moon-2012/
@Vitaliy - yes, basically (Extream long range zoom while keepinp clear optics)
The patch allows me to zoom and get a cleaner picture.
LOL
@faceydancer, because there are more videos of me using the patch. The patch allows me to zoom and get a cleaner picture.
@chrimsbroome what has this got to do with 'Very long zoom lenses on m43' topic?
I did some more zoom tests with the new Driftwood Quantum v2 Rocket patch. Thankyou Driftwood for making it possible :) - you will have to go to the youtube page to see the others parts of the zoom.
What made me laugh was the guy who took these said I was so cold that I couldn't sharpen the photo right. It looks cold poor guy.
Somebody finally bougth the SLR Magic Spotting Scope and showd off its optics. I must say you won't be that disappointed and I think its worth the money they ask for it don't you.
I could of sold this lens and somebody would of got this zoom. Glad I didn't sell it!
check out the video :)
I've been using a Pentax-K mount adapter from Ebay along with 50mm f2 and 135mm f3.5 pentax prime lenses on my GF2 and have been happy with the results. Sample of each lens from same spot. The 135mm needs bright light to work decently at all handheld, so generally I've used it on a tripod. Since I don't have money to spend on m43 format lenses right now, the ability to use older stuff has really extended the camera. Without OIS these lenses get really shaky on handheld video. Someday I'd like to pickup a modern pentax dslr so I can stabilize them in the body and use them without 4/3 sensor cropping.
