Minolta 2x teleconverters (3 versions shown)

[Pontus]

Sorry about the lousy picture taken with my iPad in a dimly lit room.

I'm showing my three Minolta 2x Teleconverters:
MD 2x TELE CONVERTER 300-S (for lenses shorter than 300mm)
2x TELE CONVERTER 200-L (for lenses longer than 200mm)
2x CONVERTER for MD APO TELE ROKKOR (for the 400/5.6 APO)

The last two seem identical except for the marking. There is also a 300-L teleconverter which is optimised for lenses longer than 300mm. A bit confusing really...
