Confused over lenses
john
knowledge. What I want to do is increase the zoom on my canon A70. It has
3.2MP and a 3x digital zoom plus a 3x optical zoom. I have been advised to
leave the digital zoom turned off as it decreases picture quality. The 3x
optical alone is pretty limited and I see from the manual there is a 2.4
telephoto lens that can be bought and by using the release button on the
body of the camera remove the current lens and use this in it's place.
My question is if I remove a 3x optical lens for a 2.4 telephoto lens surely
I am reducing the zoom ability of the camera. After all 2.4 is less than 3.
At this stage I am sure the more knowledgable members are having a good
laugh at me but please remember I am totally new to this and the terminology
of photography. I am sure I have got it wrong somewhere so any explaination
would be appreciated.
John.

Hehehe... No the 2.4 number is a multiplyer. (2.4x) So the
current 35mm ~ 105mm with the TC-DC52 in place becomes about
85mm ~ 250mm. Also AFAIK it doesn't "replace" your current
lens. It's an add-on lens. Like taking a picture through a
magnifying glass (kinda). BTW, you're also going to need the
LA-DC52C Conversion Lens Adapter to fit that converter lens.
The LA-DC52C adapter also allows the use of any 52mm filters
or lenses. So you can also buy 3rd party lenses and aren't
forced to use the ones supplied by Canon. While the Canon
ones will be high quality you may want more or less power
added than the 2.4 they supply.
Another thing worth thinking about is that at that focal range
you will /need/ a tripod or monopod in the majority of shots.
Table-pods and beanbags work as well.
Have fun learning about camera stuff...! It's kewl!

off. I knew I was missing something. So far I am having a great time with
this camera and my only regret is not saving the extra for a digital SLR as
I am getting addicted to my new toy. Maybe the SLR will come in time.

of your current cammera and you can sell it or trade it in on an
SLR when and if you deside to get one.

A what? A "Nikon C750"? Never heard of it. You mean Olympus C750?

All lenses "distort" including the one your camera came with no
matter how much you paid. How much distortion is introduced and
wheather you're willing to put up with it or if it's even noticable
is another question.
Usually if it's got a good name on it Nikkor, Zukor, Tamron, etc.
it won't be too bad but 2 or 3 times the price of the no-name jobs
"hanging" on the rack. For example a 2.5x no-name can be had for
about $25 and at the far end of the zoom it will look ok -- maybe
very little difference! In John's case that would be 180mm to 250mm.
At 85mm however, there will be all kinds of /noticable/ aborations.
How it does at 95mm ~ 180mm depends alot on just how crappy it is.
For $25 I would imagine some color shift and silhouetting. Maybe.
Again though, I haven't been to a shop yet that wouldn't let you
screw thier display model onto the front of your camera and take
some sample pics with it. Get those pics on your computer and
then /you/ can decide what level of lens you want or wheather
it's any good.
Usually cheep-o telephotos are ok for non-professional use but
the wide angle and fisheye types are too terrible and you'll
want to pay the difference for the better quality makes. Usually.
