Wide-Angle Lens Usage Questions

I read in an earlier post that someone liked to keep their wide-angle lens on all the time which made me curious.

Is there any compelling reason why you wouldn't want your wide-angle lens on the camera all the time?

What impact would that have on focusing, exposure, shot composition, shutter speed?

Alain,

Sorry for the edit of your post. It's a bit difficult on this forum to focus in any other way on the point to be addressed.

Re: wide-angle lens.

Most of what I need to do focuses(pardon the pun) on the close-up.

Therefore I have yet to use my wide angle lens.

Know of anyone who wants to buy one?? :)

Take care.

Wide lenses should only used... for wide scenes. Then you should put it away. Wide lenses tend to have chromatic aberrations, they blur the image, and the more you zoom in the worse it get.

I have the Canon wide and enjoy using it when shooting wide. I have found it great, especially in shooting....cycling. However, it is heavy and while it will not affect focusing and exposure functions perceptively, it will slightly soften, or degrade the image quality, vs using the lens unemcumbered. It will also introduce mild barrell distortion, which cannot be escaped when using wide adapters.
One advantage to shooting with the A1 is getting to use that sweet L series lens. Don't handicap it by using wide adapters more than you have to.

The IAF can't be used (the lens blocks the sensor). The Autofocus function still works.

Even if you focus manually and just sometimes use the AF button this could be enough reason as there's quite a difference in how well it works.

I will be much more selective in my usage of the wide-angle converter.

Like Giovanni said - I'll use the wide-angle converter when I need a big wide-shot, otherwise it's staying in the camera case.

I'm interested in capturing accurate, natural, and undistorted footage and this feedback has been very helpful. Thank you everyone.
