20x lens - what's the story?

Re: 20x lens - what's the story?
I've had the 3x for some years now and am very happy with it. It's extemely wide. is only 23 oz. and balances on the camera very well. Has very little distortion, unlike the screw on adapters. The depth of field is deep and it's recomended that you focus manualy. Is very good for confined quarters, in cars and small rooms. Is also good for interviews bringing the on camera mic closer to the subject.
I'm pretty happy so far with the 20x also. It's a big improvement over my original 16x. The focal ring is a lot less slopy. the zoom ring can go the whole zoom range in less then a rotation. The push to focus button is very eazy to find with your finger. It focus much faster and sharper then the original 16x. It's a bit more wieght then the old 16x. Canon has helped a bit there, the view finder is made to move forward an inch or so, so you can put the camera more on your shoulder.
What is breath?
;D

Re: 20x lens - what's the story?
Breathing is a term that is used when you are focused on a subject at a certain focal distance. You then perform a rack focus to a different subject at a different focal distance. During this a small shift in zoom seems to occur even though you have not touched the zoom at all. You will see this occassionally in Hollywood caliber movies also but it can be deemed undesirable in the right cicumstances. often a small pan or some otther camera movement can be made at that moment and draw attention away from this.
This is not a defect as much as it is just the nature of optics in certain situations with certain lenses.
