attempt to clarify and/or correct that information.
In this case, the information was that 20x performance could be obtained from an add on. As you now confirm, this is a risky prospect. It may not work, and there is no way of knowing until after the money is wasted. Further, your test process does not say what the effect on low light performance is. That is critical information since the original poster is concerned about low light performance. Even in the best of cases, adaptors degrade the camera's ability to function in low light conditions. Even one of the best cases, a Canon adaptor made for Canon lenses, causes a loss of two f stops in performance. The f stop on a GL2 at one shutter setting changes from 1.6 at maximum wide angle to 2.8 at maximum telephoto. That means that the $700 camera has to achieve an aperture of 1.6 at its full telephoto setting, and be coupled with an extender that limits the light loss to two f stops before it will match the GL2's performance. I'll leave it to you to figure out how likely that is.
I should remind you that you responded to my post, I did not respond to yours. It is fine to post your own experience, but you should be prepared to have errors pointed out if you do so. No one is helped if information is misleading, incomplete, or likely to be misunderstood.
