comment Is it lenses which make your photographs, not camera bodies?
@AnishaKaul That relates to "crop factor". A "full frame (35mm format)" covers what would be the space of 35mm film: 36x24mm. For further info about common sensor sizes and detailed effects, see the page on image sensor format.

comment What kind of gloves to use for operating a camera in freezing temperatures?
Same tactic I use in Maine. Lets me keep my hands warm and free up a fingertips for tactile input without exposing skin.

I feel this is technically correct and yet fails to answer the question being asked.

Take a manual lens that is similar... my memory tells me I used to have a, 28-80 3.5-5.6 Pentax mount. The aperture blade position was set with the aperture ring, and that was independent of the zoom. As it was fully manual, the camera had a lever which pressed against an arm sticking out of the lens -- blades open, or blades closed. Thus, an f/22 on that lens resulted in the same physical aperture opening at any focal length. While I observe that my fully auto cameras do have differing min apertures based on zoom, that conflicts with what I know from the fully manual. Can you reconcile that?

comment What is a photography portfolio, and when would I use it?
Hmm... I would never have asked this question, yet the "winning" answer taught me something new. Definitely worth posting, and I'll gladly let him boost for it. +1 for a question I should know more about but didn't realize.
