28mm vs 35mm, huge diffrence?
I'm looking for an compact, and I've nailed down to a couple of choises..

Canon G9Ricoh R8Leica D-Lux 3.

I think the best camera for me is the G9, but it only goes down to 35mm in wide, where the ricoh can do 28mm, does it make a big diffrence? How much more can I capture with the last few millimetres?.

This is a matter of opinion, really, but I think it does make a difference. To put it this way, I'd sacrifice 20mm at the long end for 10mm at the short one..

Sadly not having 28mm makes a huge difference IMO.

For example on a visit to Ayres Rock (Uluru, NT. Australia) the rock would not fit in from the most popular viewing places at 35mm, and as they don't want thousands of tourists eroding the delicate desert crust there's no walking back further. 28mm would have fitted it in OK. The workaround was to merge two shots later in Photoshop or use the camera's pano feature. With architecture that's a bad idea due to distortion..

So I'd advise getting a camera that reaches 28mm if you can. (Canon Ixus 870 at small size, Fuji 9600 at large size, or DSLR plus 18-135 [14-xxx if Olympus] lens perhaps?).

Quite a lot. It's not the difference in mm that matters, it is the ratio. the difference between 10mm and 20mm is huge (a factor of two in the length of something on the image means that you get 1/4 as much in the frame at 20mm as you do at 10mm). The difference between 190mm and 200mm is more or less nothing. So the 'last few millimetres' get more and more significant the fewer millimetres there are..

The difference in area covered between 35mm and 28mm focal lengths is about a factor of 1.6. At 28mm you would find it much easier to get groups of people, buildings, interiors, landscapes etc. in the frame. THis will be much more important than small differences in range at the long end..

Best wishes.

For shooting buildings, both outside and inside, it is often important. Very difficult to back away from a tall building when it's jamed in with other buildings. For landscape scenics, not so important. As the 28mm makes the detail in the shot tiny and harder to see. Which is not always desirable in a scenic shot..

Also, from an optical perspective, it's harder to build good macro capability into a 28mm design..

On the whole, I do not consider 28mm a must-have. But then I'm not paid to shoot architecture either..

At this end of the scale it makes a big difference. A small difference in focal length equates to a large difference in field of view..

Let's say for example that we use a 35mm lens to shoot a subject at a distance of about ten feet. The width of the scene captured would be about 10 feet..

That is regarded as moderately wideangle compared with a "standard" 50mm lens. At the same distance, it would capture a width of just 7 feet..

On the other hand, a 28mm lens would capture a scene of 12.5 feet wide. For an indoor scene this can make a significant difference..

(In fact at any distance the relationship remains the same, a 28mm lens would capture more than the 35mm lens)..

To some extent this is a way of seeing. Our eyes (and brain) naturally see a wide view of the world, and lenses such as a 28mm just begin to see the world naturally. A 24mm lens for example, at the same distance would "see" a width of 14.5 feet. How wide is the view of the world that *you* see at ten feet?.

The real point is, the difference between 35mm and 28mm is significant, while 335mm to 328mm would be virtually identical.Regards,Peter..

Here's a comparison; 24mm on top, 35 mm on bottom,, same scene...

It can make a huge difference for (usually) interior shots where you simply cannot back up enough...
