Hi!

I know that the original k-mount lenses can be fitted onto the *ist Ds.

Couple of questions:

When looking into the viewfinder, will it tell you what aperture or shutter speed you are set on? Can it read it from the original k-mount lens? Is there a light meter which reccomends what shutter or aperturei should be on

Does shutter or aperture priority work with the originalk-mount lens?

The original k-mount lenses are not autofocus.

Thanks!

not the aperture, but you just looked at it on the lens, it does tell speed and if manually focusing it will flash and beep when focus is right. i've got 3 Ks and they work marvelously.
A & S seem to work alike altho i never use the shutter pri. mode. in aperture the speed change by itself. in manual you set the ap. and hit the AE-L button to set the speed.

go for it!!!

I am lifting this quote from a previous response of mine to a similar question:

Since I purchased my DS last month I have used all the following lenses on the DS with no problems whatsoever:

Manual lenses used with adapter:

M42 Manual 55mm f1.8 (1969 - used on my Spotmatic and others with adapter)

M42 manual 135 f2.5 (1970's used on my Spotmatic and others with adapter)

M42 manual 200mm f5.6 (1970's used on my Spotmatic and K1000 with adapter)

Auto lenses:

SMC Pentax -A 50mm f1.7 (1970's used on my K1000, P30T, P50)

SMC Pentax -A 50mm f2.0 (1970's used on my K1000,P30T, P50)

Takumar - A 28mm f2.8 (1970's used on my K1000, P30T, P50)

SMC Pentax - A 35-80mm f4 - 5.6 (1990's used on my K1000, P30T, P50, ZX50)

Sigma Zoom AutoFocus 100-300mm f4.5-6.7) (1990's used onK1000, P30T, P50, ZX50)

These lenses also work backward compatible as I indicate. Of course an AutoFocus lens will work on a manual like the K1000 however the auto focus function will not be available (obviously) Ditto for AutoAperture, but they all still function in a manual mode.

Is there any other camera company that affords this level of compatibility?

Yeah, ain't it great?

A few folks I have met recently with new Canon 20 D's have asked "why did you get a Pentax?"

So, other than outstanding build quality, excellent ergonomics and diminutive size, fantastic image quality, I let them know that all my lenses, going back to M42 screwmounts from 1969, work very well on this DS.

That's why I bought the DS!!

i heard that to change the aperture on the *ist ds manually you have to hold down the button right next the the shutter release. is this awkward? can you look through the lens and easily change aperture whle holding that button down? does it require two hands.

basically the reason i think i want the *ist d is because it has external controls (no menu browsing), a seperate switch for aperture, and a nice whining sound when it realeases the shutter!

i want to buy the cheaper camera....but someone has to convince me that my criteria are stupid for choosing the *ist d...
