Is my Sigma 28-90 F3.5-5.6 Aspherical Macro lens compatible with digital SLR?

I'm on the hunt for a good digital SLR, but I really like the lenses I'm used to working with on my current SLR. Where can I find a list of compatible camera bodies to go with my current lenses?
I've googled, but can't seem to find the right page. Can you help?

Sorry, it's a Pentax mount. But I know that some lenses are compatible on more than one brand of body.
Thanks guys.

All three contributors are right and you did not mention the mount and it is hard to say whether the lens is compatible with a certain mount.

The reason you could not find an answer on the net is the lens is discontinued. However, the lens seems compatible to Nikon, Pentax and Canon based on the links given below.

You don't say what lens mount/body you have. Generally, if it fits a current Nikon, Canon or Pentax, etc it will fix their digital SLR bodies. Older lenses may not have full functionality. For example, the Nikon D40 requires lenses with the auto-focus motor in the lens itself for auto-focus to work. The other Nikkor lenses will need to be manually focussed.

For digital bodies, it will cover the equivalent of 42-135mm, a normal to telephoto range.

is that pentax mount? if so will fit pentax.

what brand is the mount for?

28-90mm will have different zoom numbers depending on the brand and the conversion ratio of the brand (1.3x , 1.5x, 2x)

give more info

In total agreement with the answers above. Sigma makes their lenses to fit many different brands of cameras, including their own! What camera are you using it on currently? That would narrow down our recommendations.
