Opteka High Definition 500mm preset telephoto lens is great for nature and sports photography. The amazing power of this lens gives you the equivalent of looking through a pair of 10x power binoculars


Yet your 400mm telephoto is giving way more than 10X magnification there - unless I am being a total moron?

Oh crap. I am being a moron. 400mm is way more than 10x12mm. Apologies to all involved for having to read my demented ramblings.

Magnification is not the same as zoom ratio. Remove moron status

Not a techy but, to take a wild guess, I would say that the photobucket software is aiming to provide a file size which is in a ball park range for all images irrespective of conten. In some cases this may mean larger (or smaller) images displayed.

Pure guess. I look forward to the real answer.
