comment Why are Micro Four Thirds lenses so expensive compared to Canon?
Please take into account that manufacturer may label the lens for the equivalent focal lenght, rather than the actual (physical) focal length. I have owned two Olympus cameras (E-300 and Evolt E-500), a currently have Canon 50D. When I compare them for crop factor, If I set the lens on both brands on the same fl mark, I get quite similar framing for the same scene/distance/point of viev. (Canon lens being an EF-S one).

comment When does it help to use scene modes?
It helps when it is necessary for a person not knowing how to use your camera properly to take a picture with it, like when a family member takes a snapshot of you in a vacation. Instead of explaining anything, just pop in a scene mode. It also prevents from loosing your settings on the manual mode (in most cameras).

comment Why is my SD card filling up too quickly?
Just in case: IF you used a MAC computer for reading and deleted some of the pics, they actually are still in the card but as hidden files. (A Windows system configured to show hidden files will help. An Android system will show the files and allow you to delete them). If I recall correctly, MAC puts deleted files in a .trashes folder.

comment Why do some umbrellas have black cover instead of silver?
the cover indeed is on the convex side. What I meant is that when using umbrella in reflective mode, part of the light bounces right away on first hitting the white material on concave side, but almost half goes through and is possibly lost. Using a silver cover on the convex side, facing the white fabric would catch this light and bounce it back to the translucent white, where it would shine trhough back to the concave side, adding up to the light that bounced directly, saving you almost a stop of light from your source.

comment If I swallowed my SD Card would it be readable when it emerged?
I've seen a lot of suggestions about micro sd cards. Why not having a big piece of chewing gum and sticking the microSD in there. IF you swallowed it, it would lessen chances of sticking in throat and would reduce exposure to acid, but you may manage to escape without having to "wait", specially if you do the swap with a card full of "innocent" picts.

comment What kind of earplugs are best for concert photography?
I have successfully used a pair of earplugs from my phone to protect my hearing while usind a reallly noisy grinder (I know it's not the same) in a confined comfined workspace. They were not plugged to the phone nor a music player. They were in ear type, of the kind that are "noise blocking" with a mushrom-like rubber fitting. I'm not suggesting these for long term use, but they can serve in an emergency if you have them in hand.

comment How to record the viewfinder while shooting?
I performed the experiment using an Olympus XZ-1 on the viewfinder of a Canon 50D. The Olympus could get an understandable image but it was not wide enough to cover the full viewfinder's image plus the exposure meter and the outer indicators. Also tried with a cell phone's camera, but it had an even narrower angle of view.

comment Why don't most cameras store filenames based on date and time?
The Brand Olympus has a simple system: it usually starts its names with a 'P' or '_'(don't remember what means but it's related to colorspace), then a digit for the month: 1,2,3,4,5,6,7,8,9,A,B,C, two digits for the day and four other digits for correlative. Thus, file PC083651 was shot on December 8th. It is indeed VERY useful and at least I have never had a problem. It's only odd if you shot during Dec 31 midnight, because "older" file suddenly gets on top of the alphabetically ordered list. Maybe they have a patent and it keeps the rest from doing it.
