Yes. See: http://www.amazon.com/Pentax-Digital-Reduction-18-55mm-3-5-5-6/dp/B000FTLSR0/ref=sr_1_1?ie=UTF8&qid=1419199194&sr=8-1&keywords=k100d

Yes it will. The K30, like all of Pentax's digital cameras, will accept any K-mount (bayonet) lens. Just be aware that older lenses may require manual exposure.

yes it will //// amazon doesn't know what they're talking about - by the way I recommend you use this with the K-3 // a great combination !!

I don't know but it should work unless Pentax have changed the IR design. I use it with my K5 and it works fine. No problems so far.

I have the k53f and it works fine. YOu would have to ask the seller if its compatible :)

I have a KL-100 and if your model is an updated model of mine it should work just fine.

The d100 has a focus motor in it, as I understand it, so this should work. I have used it on d80 and a n8008 very nicely.

Yes, I'm using it with the d7100 and they have the same USB ports. You should be fine.

I do not know if this is compatible with the K50. I have used it on a K10D and my current K30. Are you aware of the Pentax Forum? Based in the UK, worldwide participation, funded by member contributions. Try http://www.pentaxforums.com/ and see what you can find out. I highly recommend the product. AA batteries are everywhere and chargers for the proprietary Pentax battery are not. John Blair

If the lens is a Pentax Bayonet mount it will fit this camera. I use several manual lens from the 1980's on my K20d. The manual lenses will of course only function as a manual, and you will have to set aperture and focus yourself.

I use it for my k10d I would assume it would with the 20D it is cheap buy if it does not that was my logic when I bought it and I love it!

I use it in my D200 which is also the same as the one in the D100 and have had no problems.

I continue to use The Quantaray 70-300 with a K10D and a K100; I'm sure it will work with an istd. I used the nearly identical Sigma 70-300 on my old istd prior to giving it to a friend.

Yes, it should. As far as I know (and I have both a K10D and K-5), all the Pentax DA lenses are compatible with current Pentax digital SLRs, that's what the "DA" in the name of the lens means. You can find more detailed lists of what Pentax lenses are and aren't compatible with various Pentax DSLRs at Pentax's website, although you may have to dig a bit to find it.

I'm pretty sure it does. It works beautifully on my D3200, so I'm sure it would in the D7100.

Yes it will. The Pentax K-30 has the same K mount as all the other Pentax DSLRs.

I doubt it. Cause it only works with D7000. And one of my friend told me it didn't work for him in D7100.
