Re: New Canon 15x50 IS!!! Don't like em...

Hi
I just got a pair of these 15x50's last days (not a brand new - but a 6 months one used very rare) and I found the same impression as Luigi, nothing really bad or suggesting some real failure on it electronic parts but the image (when IS engaged) drops a bit in sharpness and that fast softening is there coming and gone depending on how steady it's holded...the more steady the less noticiable is that effect.
The collimation is spot on with no one kind of eye strain but I could notice also some color fringing under the daytime mainly on some black objects skylined.
I thought the Canon IS system should work a bit steady - I owned in the past a Russian Newcon 16x40 Gyro stabilized and in these the stabilization really is very steady with no one kind of image degradation or softening, in fact I could see (believe or not) the Saturn's ring in some very good nights...the drawbacks are their heavy weight (2,10kgs) and they are terrible for panning and also their optics show a strong yeloowish cast -I believe the Fujinon 14x40 IS and the Nikon 14x40 IS use the same Gyroscopes technology.
Backing to Canons - it's clear that than more steady they are holded the better the IS works - with the gyroscope system however don't matter how steady (when not panning) or not they are holded the image don't loss quality...the Canon needs some hands help to be really work steady (this is just my opinion), I noticed if braced the IS works better...it's very difficult in fact to know if we have here several Lemmons around or if this is a owner to owner particular impressions...
Luigi you can find anyway some comments about this matter just reading a recently post here (I hope).
