The good thing about shooting didgatal is that, if the exposure is wrong, you''l find out. About Tamrons success: Since autofocus have prevailed, the sale of Adaptall lenses(mounts must have declined dramatictly. I am buying the KA adapter from Jim,, so I'll get a chance to check it out on my 'ist D before relying on it for film cameras.

Few years back Tamron introduced a P adapter for program Carl Zeiss contax bodies. At that time i had AX and was willing to purchase this adapter but in another forum this P adapter was discussed in detail but results were the same overexposure in P and SP mode. For instance Contax MM lenses function in all mode on their P bodies but Yashica lenses (a subsidiary of Kyocera) only do AE/M modes. It is obvious tarque of aperture leafes and shutter combination differ so perfect exposure is not possible. i am not engineer but it is just observation. If Tamron has devised such P adapter with perfect results for different camera manufacturer Cos. then i think it would have been the third largest optical co and many amateur on budget will pray for their success in future endeavours. Even Chinon P gears (CP5,6,CPX) work in P mode with original Pentax K lenses but whenever i tried with Tamron with different zooms/prime over exposure or poor results faced.. If my knowledgeable colleagues have ever received excellent results with this combination will appreciate his/their expertise just to increase my knowledge and thus will be saved from budget phemenon every month & reduce my fear of being cut with knife by my wife which is perhaps global tragedy with the innocent hobbists. Is not it?
