Q: 1. Will this lens work with a Pentax K10 ?

Q: 7. will it work as a full frame on the new Pentax k1?

A: The Pentax HD Pentax DA 40mm f/2.8 Limited Lens is designed for use on APS-C sensor cameras; however, many owners and users of the lens have often stated that they happily use this lens on their Pentax 35mm film cameras and the lens does cover the full image frame. As such, the lens should also work for use on the full-frame Pentax K-1 DSLR camera. (Do note this claim has only been made about the Pentax HD Pentax DA 40mm f/2.8 Limited Lens, and does not apply to other Pentax DA Limited lenses).

Q: 8. One of the reviews mentions they didn't like the manual aperture but the picture shows an A setting on the aperture ring which I assume means auto. Thus I would expect that the aperture could be controlled with the control dial either directly or adjusting the shutter speed. Can someone provide the answer?

A: When the lens aperture is set to 'A' the aperture is controlled by the camera and auto aperture control modes, or through the camera controls in manual aperture control modes.This is the same on all Pentax 645 lenses with the 'A' in the lens name, and you can verify by setting if the aperture ring has an 'A' setting.The aperture ring merely gives you the option to go full legacy manual mode, which is sometimes handy, but for the most part I leave mine on 'A' and even if I take a picture in manual exposure, I set the aperture with the camera wheel.

Q: 9. Is this lens sealed and water resistant?

A: Unfortunately, the Pentax 35mm f/2.8 macro lens is not a WR lens, so is not weather sealed. The only macro lens from Pentaxt that is currently a WR lens would be the Pentax 100mm f/2.8 WR Macro lens (B&H # PE10028MDFAW).

Q: 10. Is this lens compatible with the Pentax K-5?

A: Yes it is compatible with Pentax K5
