Crop Or Magnify?

In the quest for magnification and image resolution, is it better to crop an image in the computer rather than resorting to the use of teleconverters (1.4x – 2x) in the field? I am aware that there will be a pixel reduction with the former as against more glass with the latter and the possibility of a poor optical match.

What is your recommendation for panorama equipment? I see a number of companies that offer accessories that fit on a tripod for very precise positioning of the camera for each image in the panorama.

Reaching Out

I have an excellent 300mm ƒ/4 lens and would like to increase the magnification using a tele-extender. I’ve been told that this will degrade the image quality and I won’t be happy with the results. What is your experience using these add-on magnifiers?

The Mobile Photographer

I’m limited to movement in a walker or electric cart. I would like to start photography again. Is there a tool that could be clamped onto the walker or cart that would hold a camera out of the way while I move into position and then would permit the camera to be swung around to take the picture?
