Ska köpa ett macroobjektiv 90 mm, kan jag ha Tamron AF 90mm f/2.8 Di SP Macro Lens f/ Pentax K-7 till Min K100D?

Yes.

Are you using it on K-7 or K100D?

It will work with both.

Let me clarify what the auto translation made less than clear: The lens is being sold as "for K-7", and Katta wonders if it will work on the K100D. (And of course it will.) (Our translation system is surprisingly good, but still very bad.)

Any lens that fit the K-7 will fit your K100D. Lenses with only SDM and no screwdrive autofocus gear from the camera body will be manual focus only since the K100D has no SDM contacts. But it is only Pentax that make such lenses. The 17-70mm is the only one I can remember. The Tamron 90mm macro will work fine on K100D.

Just want to point out that when it comes to macro one can work quite well without autofocus, or to say it the other way around, autofocus is often not much of a help, so looking for 2nd hand manual focus 90 or 100mm lenses may be an interresting alternative.

Jag kan svara på svenska också ifall översättaren rör till det här:

Varje objektiv som passar på K-7 passar också din K100D. Objektiv med endast SDM utan autofokus-överföring från kamerahuset kommer endast att kunna fokuseras manuellt eftersom K100D inte har SDM kontakter. Men det är bara Pentax som gör sådana objektiv. 17-70mm är den enda jag kommer ihåg. Tamron's 90mm makro kommer att funka bra på K100D.

Vill bara påpeka att när det gäller makro kan man klara sig ganska bra utan autofokus, eller med andra ord, autofokus är ofta inte till någon hjälp, så det kan vara ett intressant alternativ att leta efter begagnade 90 eller 100mm objektiv med manuel fokusering.

should work, it's a screw driver lens.

you'll need dedicated flash though for macro shooting. the lens has built-in, not removable hood about 1/2 of lens retracted length. it will cover subject from built in flash when shooting 1:1 to about 1:1.5 focus distances.
