Re: Semi OT: huge lenses for Olydak

You just don't get it. The Olympus has a 2x effective focal length 
multiplier factor this makes it a 600/2.8. To get that with a 1.5x you 
need a 400/2.8. Go see what the size/weight/cost difference is between a 
300/2.8 and a 400/2.8.

Hallo,
the 2.8/300 has a filter size of 112 mm and it is longer as 250 mm. So, it
has the same size as a 2.8/300 for 35mm systems.
So, where is the advantage, in size or price?
