How can I find out the comparison of the Digital SLR lenses like 18-135, 18-55, 18-70 and so on to lenses used on 35 mm cameras.
Really easy “Google†it! http://forums.dvdoctor.net/images/smilies/rolleyes.gif

I copied and pasted your question

Charles, do you mean comparison of performances or prices, or of lens angles relating to 35mm SLR? the latter is pretty easy.
As Alan says it's pretty easy. It's only worth doing though if you're familiar with focal lengths on a full frame camera.
To say "digital" is a bit misleading as some digital SLRs have a "full frame" sensor. Some have a crop factor of 1.3 but the majority (APS-C sensor) have a crop factor of 1.6.
The view through an 18mm lens on a 1.6 crop camera will be roughly equivalent to looking through a 28.8mm lens on a full frame camera (18 x 1.6).
Use the same arithmetic for other focal lengths.
In general on a film camera an ultra wide lens would be 17mm, a wide angle 28mm, a portrait length prime lens 100mm
On an APS-C digital SLR an ultra wide lens would be 10mm, a wide angle 18mm, a portrait length prime lens 85mm
If you want to compare quality and features of lenses then this is a good place to start.
Many thanks all and thank you very much for your support but, I must say that I am more confused than I was before. As I am thinking to go Digital SLR I wanted to know what is the meaning of all the number of 18-135, 18-70, 18-55 and many more, compare to 35mm lenses.
I am considering purchasing a Nikon D 80 18-55 lens supplied by Jessops in Coventry. As a retired person this is in my price bracket, does any one has any comments to make, the camera would be required for only general photography.
Charles,
18-135 means exactly the same on a DSLR as it does on a film SLR but, not all DSLR's have a sensor as big as 35mm so, you have to apply what is called a crop factor and in the case of the Nikon D80, the crop factor is 1.5 so, the effective field of view for the 18-135 is 27-202, so that 18-135 lense would act as if it was a 27-202 lense on a film SLR.
The D80 did not have a good reputation for reliability and it has been superceded by the D90 which by all reports is a major step up in image quality and performance, it also has a video mode.
Cheers John
When you say "I wanted to know what is the meaning of all the number of 18-135, 18-70, 18-55 and many more, compare to 35mm lenses."
Especially the bit "35mm lenses", I hope you're not confusing focal length of a lens and 35mm film?
In the phrase "35mm lenses" the 35mm isn't talking about the focal length of the lens but the size of 35mm film used in film SLRs.
Lenses for film cameras still come in many focal lengths. If there's two numbers it's a zoom lens 28-300 means you can zoom from 28mm to 300mm (10 x Optical Zoom)

Also have a look at Canon range of SLRs such as 450D and 1000D
