[langtitle=pl]Are those lenses suitable for Pentax?[/langtitle]

Hi,

I have just bought my first lenses camera - Pentax K200D. I am quite unexperienced, so it's a little bit confusing for me to analyse if I can use lenses Tokina SD 70-210 easily? I have a chance to buy it for a very low price, I do not care if there is AF or MF only, but the matter is if I can easily mount it and if my camera "requires a lens with ring controlling aperture or not"? This is a question I got from the person selling those lenses and... I am not sure of my camera requirements yet, but have to decide quickly if I want to buy those lenses or not.

Thank you in advance!

Does the Tokina SD 70-210 have the Pentax K mount?
Find out which mount the lens has and you get the answer.

"Requires a lens with aperture ring or not controlling" ? This is a question I got from the person selling Those lenses and ... I am not sure of my camera Requirements yet, but have it Quickly decide if I want to buy Those lenses or not."
- This means that it is full frame older lens that has either manual/auto aperture/ focusing ring. Ask yourself, if you want auto or manual control on the aperture and/or focusing ring? Then you will have the answer to your question.

if it is a K bayonet mount, it will work with your K200D

If the lens mount says PK, PK/A or PK/A-R you are set to go. You will have to set a custom menu setting that says Allow Aperture Ring if it is just a PK. With either of the "A" options, I do not believe that is necessary. In the case of the PK/A-R, DO BE CAREFUL. Do a search either on the Forum or google for Stuck Ricoh Pin. It is a condition where a pin meant for Ricoh cameras will drop down into the Auto Focus screw drive on the Pentax mount and essentially lock the lens on to the camera. Not all lenses that have the pin will be a problem but it is something to be aware of. In most cases, the pin can be removed for trouble free operation. That's the first issue. The Second is that some third party lenses have a flange on the rear (take one of your other lenses to compare) that is too big. While these lenses will mount fine on a Pentax FILM camera, they will NOT mount on a Pentax DSLR. This too can be fixed if you want to tinker with it..

Good luck and enjoy your new camera.
