Default 24mm vs 28 mm wide angle

I'm trying to decide if I need a camera with a 24 mm wide angle or can I get away with 28mm. I would appreciate it if someone could post an indoor and an outdoor shot taken with each lens to compare. Am I asking too much of the kind people who respond to these forums?

It pretty much depends on what sort of photos you are interested in taking. I almost never use anything wider than about 36mm, even for inside shots on small rooms, but know people who can't live without 18mm or less.

Since I've tried the 24mm, I could never go back !

Personally, I think 24 mm is ideal for all that !

When I visited the British Museum, those 24mm lens were perfect...

But 18mm creates too much distortion !

24mm dx = 36mm ff.. dx meaning crop sensor with 1.5x multiplier and ff being full frame dSLR or 35mm film cameras.

I have a 28mm and use instead my 10-24mm for indoors instead if I need to get a shot in tight spaces. I am aware of distortion but it is better than no shot at all. It all depends on what you like or will tolerate as far as distortion or try to correct in post process and that also largely depends on what software you are using.

I shot film since 1971 and never used a lens wider than 50 mm, never missed it. Been shooting dslr since 2006, widest lens I have is 28mm dx= 42mm fx. Just because I don't do wide angle doesn't mean you won't. This advice is useless. It's up to you.

Here are three sources on the web comparing FoV of various focal length lenses on a full frame body(use the equivalent that matches your sensor).
http://en.wikipedia.org/wiki/Angle_of_view

http://www.tamron.eu/en/lenses/focal...omparison.html

There are other sources as well but this was a quick Google.

Here is a useful tool site - Photographer's Calculator, which answers many questions.
The easiest understood comparison of the differences between 24mm and 28mm is the angle of view (in degrees), which varies with sensor size (or crop factor).

........................... 24mm . 28mm .. difference
Full Frame Camera 73.7 ... 65.5 ... 8.2 degrees
1.5 crop camera ... 53.1 ... 46.4 ... 6.7 degrees
1.6 crop camera ... 50.2 ... 43.8 ... 6.4 degrees
2.0 crop camera ... 41.1 ... 35.6 ... 5.5 degrees

Full Frame Camera would be Nikon, Canon or Sony
1.5 crop camera would be Pentax, Nikon, Sony
1.6 crop camera would be Canon
2.0 crop camera would be a 4:3 camera
