Question about Pentax Normal SMCP-FA 50mm f/1.4 Autofocus Lens

1 Answer

New SMCP-FA 50 1.4 will not work on my K100D Super or K10D

I purchased this for my daughter for Christmas.  When installed on her K100D Super the camera will not function.  I tried it on my K10D and the same thing happened.  Displays blink but no adjustment can be made, can not see through the viewfinder, even the flash will not open. It seems to short out all electronics. Is this lens defective?  All our other lens function perfectly with these cameras.

You are probably right - it sounds like it is not connecting right - I would take it and the camera to the store and check out another lens!

What does smcp -fa mean


SMCP- means: Super MultiCoated Pentax (a term that refers to the anti-relctive coatings that Pentax has been using on its lenses for years F-means it is a lens designed to cover the larger area required of a lens for Film camera use versus the smaller sensor of the Digital SLRs Pentax also makes. Pentax also makes DA lenses , which will only work with their digital SLRs. A- means it will work in fully automatic mode on cameras that have the ability to set shutter speed and F-stop automatically (most modern Pentaxes) It should also be noted that all DA and FA pentax lenses have a modified version of the original Pentax K lens mount, which replaced their first lens mount, the universal M42 used by so many early film SLR manufacurers- this concluded todays pentax lens history

I have an old Pantax 35mm SLR camera (zx5). Would the lenses still fit the new bodies or do I need to purchase an entire new kit?


Nope! Your old Pentax (and Taukimar!) lenses will still work. Any type of "K-Mount" lens will work on a Pentax digital.

I BOUGHT A PENTAX K10D THAT CAME WITH A VERY NICE AUTO ZOOM LENS. I OWN SEVERAL OLDER PENTAX LENSES THAT I USED ON MY K1000 CAMERA AND I WANT TO USE THEM ON THE K10D. I CANNOT FIGURE OUT THE SETTINGS THAT...


Hello,

I don't own a K10D, but I do own a K100D which I have successfully used both manual focus & auto-focus lenses from my old Pentax stash!

1) If it is a manual focus lens, you need to turn off Autofocus on the body of your K10D. On my K100D, there is a switch on the side of the lens mount that says [-MF or -AF]. "-MF" is manual focus mode & "-AF" is autofocus mode. Since your lens doesn't have autofocus capability, turn it to the "-MF" mode.

Also . . . When I press "Menu" and go to "Custom Setting", I change two settings . . .

1) I change "Using aperture ring" to "Permitted". This allows you to use manual lenses (M lenses) that do not have an auto(exposure) setting, and also lets you use Auto lenses (A, KA, KA2, FA, etc.) in either the Auto or manual aperture setting modes.

2) I change "Fl with S lens used" so that even with a manual focus lens, although I don't have autofocus capability, my K100D beeps and shows a little red square in the viewfinder when I have successfully focused manually!

The K10D should have the same options.

This should get you up and running!

I have had a load of fun with my old lens on my new digital Pentax!

Take care & Happy Imaging!

The Power Zoom appears to be locked at 80mm.


(I just cut-n-pasted the comment into the solution so this shows up as a solved problem in searches.)

"I've found the solution!
Just goes to show that sometimes it's worth simply calling the importer's service department, who told me in 30 seconds!!
Hold the zoom twist-ring and push, or click it up or down, depending on which way you are holding the lens.
So simple; I even accused him of not knowing what he was talking about.. and of course apologised profusely when it suddenly happened."
