Arsenal MC 2x Teleconverter K88




This large multicoated 2x KOHBEPTEP for Kiev 88 mount cameras (including my Salyut-C) was supposed to be in lieu of more expensive long lenses, which I then couldn’t resist buying anyway. So it hasn’t seen much use. I should throw my Vega-28B on it and see how it performs!

I believe the K-6B refers to the mount type.


Attach the converter to the camera, then the lens to the converter. To remove, do the reverse. It’s more difficult to take the 2x off the lens than to take the lens off the 2x. Besides the loss of two whole f-stops, the other thing to consider is that the handholding rule of thumb is to shoot at 1/focal-length as the slowest shutter speed, eg 1/60 if you’re handholding and shooting a normal 50mm lens. Add a 2x and your focal length becomes 100mm, suddenly you should be shooting at 1/125 or faster to avoid camera shake. Add the 2x to your 200mm and… get your travel tripod out!
