It could be cost but also it could be that the technical solution was difficult and for the peceived benefit not worth pursuing.

I think most of us may have settled for using A series or later lenses with a A setting on the aperture ring. That works fine.

The details of the subject are there, but I wouldn't call it sharp really. The outlines are rather fuzzy and the contrast is quite low as well.

TCs have never been famous for crispness, although there are some very expensive marque converters for specific lenses that are critically sharp.

The exposure error is to be expected. The instruction book does say "an exposure error may occur" so you take the reading as a starting point and learn how to compensate for any errors.

It looks like there were limits to what could be achieved in a cost effective way with backwards compatibility, presumably bearing in mind that relatively few users will want the facility.

Personally, I doubt that the Minolta spec would be less stringent than Pentax's.
The Minolta lens is 1500mAh, the Pentax one 1620mAh. Whether or not the dimensions are identical or just close enough I don't know.

I'm sure in terms of Quality Control both marques have very high standards.

It's best to post in one place only. Lack of replies suggests nobody knows!

No it's not in the film, and that surprised me too. Must have been made later, cashing in on the film's success.

Goodness gracious me.

It still seems to evade many people that the NP-400 battery may be the same dimensions as the Pentax battery, but it isn't the same specification. It may or may not be insignificant, but it is rated lower than the pentax 1620 mAh.

So the statement that the battery for the K20D is shared with several Minolta cameras, implying it is the same product, is still incorrect.

Pedantic maybe but let's get the information accurate so that informed decisions can be made.

An unqualified "thumbs up" for the 12-24mm, a brilliant lens. Very accurate drawing (low distortion), super sharpness and an excellent all round performer.

If you can lift the biggest Bilingham bag after you've filled it to capacity then that is an amazing feat indeed. Only for those who can eat three Weetabix for breakfast.
