Use of lens mount adapter EF to Pentax K

[RichardZ]

Are there any issues in using an adapter so I can use my Pentax K lenses on my T100 in all manual mode?

I don't see that the T100 has the option to shoot without a lens attached, only with no card.

I don't believe you need to enable shooting without a lens on the T100 or 3000D. That seems to only apply to mirrorless cameras. Any DSLR I have ever used will always shoot without a lens attached.

When you say "without a lens attached"  I assume you mean one that is electronically compatible with Canon?  I can figure this out in all manual mode....just don't want to damage the camera...which is my concern...

It won't damage the camera. Back in film EOS days the camera would display f00. Not sure what displays now. 

I used to use a fixed aperture 500mm mirror lens.

Thanks for the information.  My Pentax K100D died and I have several k mount lenses and am not afraid to use the manual mode.

It works!  I can use my lenses...   It does show F00.  I shot three pictures using manual mode and my Kiron zoom and they came out fine.  Thanks again for the assistance.

"...they came out fine."

How about posting a sample or two of "fine" ? I have never been impressed with the old lenses vs even the cheapest new lenses.
