Praktica zoom bin's...

[johnbaz]

Hello

I have a pair of Praktica sport 10-30x30 zoom binoculars that i bought very cheaply at my local carboot sale...

the optics are fantastic for what is probably a cheap set of bins bu when i operate the zoom they go out of focus slightly, a small adjustment of the focuser puts it right..

should the image still be crisp and clear when zoomed in or do all zoom bins have to be re-focused upon zooming in? (i suspect not:( )

is there an easy fix or would this be a job for a specialist?

i have a feeling that i will have to live with having to re-focus because the cost will be prohibitive...

regards (and thanks for any help!), john:)
