35mm only or digital

Hi guys,

I've never been good at putting a correct title to a thread but I was wondering if these 2 lenses below from my Mz50 35mm camera would be ok to use on my k100d and if so are the results the same as a proper digital compatible lens

Tamron 28-80mm 1:3-5-5-6 lens
Sigma 100-300mm lens

Thanks

Jim

If they worked with your MZ-50 they will work with your K100D.

Yes, if a lens is compatible with a film camera, it'll also work on digital without any issues.

The results are "the same" if the millimeters are the same; you just have to keep in mind that the lenses will seem "longer" on the K100D. A 28mm will seem a lot wider on 35mm than on a K100D. The 18-55mm kit zoom for the K100D will give you approximately the same results as that 28-80mm on your 35mm. So if you want the same coverage, you need a different lens, at least on the wide side.

Good info above. Yes, those lenses will work as well as ever on a dSLR; they are "digital compatible". Yes, they will 'see' a narrower view on a crop-sensor dSLR than on a 135/FF frame. Yes, you will probably want to supplement the 28-80 with something wider such as an 18-55. IMHO 28-80 is a good 'people' focal range (I often use a Tamron 28-70 or F35-70 there) while 18-55 is a better general-purpose range. Do you already have an 18-55? If not, it's well worth getting, CHEAP!
