Originally posted by Wheatfield Feh. If they hadn't cheaped out on the lens mount by removing the aperture cam follower we wouldn't have to talk about the green button kludge.
When the original istD came out, it effectively wouldn't allow the use of non A series lenses.
If you wanted to use a pre A lens, you were stuck with no metering and shooting at wide open aperture.
It was only a huge uprising of bitching and moaning from the userbase, especially on the PDML that got us the green button kludge in the first place, and this on a $2K camera.
Don't wax eloquent about the GBK, Pentax only gave it to us grudgingly, and we shouldn't have to be metering with non A lenses in this fashion.
I'm not entirely sure I follow you here, wheatfield...
On my Nikon D90, I'd kill for a green button. Even the AI-S lenses do not meter with it - basically only AF lenses meter with the D90, and all MF lenses are
fully manual - with no green button equiv to help at all.
On the D200/300/700, the AI-S lenses meter (equiv to the Pentax A lenses,) but D40/60/80/90, no dice.
So, basically, it would be like disabling the A setting on all the Pentax A lenses, and then taking away the green button so all the Taks, K's, M's, and crippled A's need fully manual metering with no green button assistance. That's Nikon's MF offering, sub D300.
I don't care if you consider the green button a 'kludge', give me a kludge like that on my Nikon system any day and I'd be ecstatic!
As it is, due to that limitation and the not-so-accurate viewfinder focus light indicator, MF on the D90 is much less fun and effective than on my K20D. I was looking forward to trying out a lot of MF Nikkors, but now I'm not so sure I'll bother.
MF = +1 Pentax.
