Best Lens Choices for Canon 300D

It gives a comparison with more familiar 35mm equivalents.

In other words, the image size is not intended to be sufficient for a full
size 35mm frame.

Actually it is a moderate wide-angle to short telephoto zoom.

You must be consistent - a 50mm f1.8 will give you the same angle of view as
your zoom set to 50mm and will be equivalent to an 80mm telephoto in 35mm
terms. You need to remember that the 'standard' lens of the 300D would be
50/1.6 or 31.25 mm focal length - equivalent to the diagonal of the 300D
sensor. Corresponding magnifications and angles of view are then simply
worked out as ratios between the lens in question and your standard of
31.25mm.

I've heard that the conversion factor is actually 1.55 - not that it makes
much difference.

Hiking is cool - and your lens a good choice for the 300D - unless you can
afford a 17-40mm L series!

Some day in the future we are likely to have one or just a few sensor
sizes. When the sensors are standardized for some years and everyone has a
good feel for them, then we will talk about lenses like we now talk about
them for 35mm and medium format and large format. It of course will require
one to know what sensor size you are talking about, just as you need to know
what film size you need today.

Right now there are several sensors sizes and I would not bet that in
the next few years we will not see many more as technology limits and
manufacturing efficiencies change. As time goes on and the technology
becomes more mature I expect only a very few sensor sizes to remain, but
unlike film the driving force will be the manufacturing efficiencies not the
need for a standard film size that will be the reason.

When that happens then talking about a 37mm lens for a compact digital
or a 47 mm lens for a digital SLR or a 60 mm for a large format digital may
all mean the equivalent to "standard" like the 45-57mm lenses on a 35 mm and
no one will bother with using the equivalent language to say what field a
lens will cover.
