Oooooh I have a spotmatic and K1000 fab cameras
Alex, excellent set of images and welcome to the film area. I am very jealous of your charity shop bargain. I owned a SP 500 many years ago and is was a great camera.
This is going to make me sound infinitely unprofessional but I've been wondering about a few of the features that split the Spotmatic F from the K's and the Supers..
I'm chuffed with my bargain too, I'll have to be pushed to get rid of it!
The Spotmatic F was the king of screw threads and an absolute classic! I remember the magazine add was a picture of Alan Whicker's well travelled SPF. The K1000 was a sort of bayonet Pentax K version, retaining the mechanical shutter, but of cheaper construction, the ME super was the auto and electronic shutter Pentax offering. I am sure others will add some other comments and differences though.
Well I pass on spotties as I still occasionally use my Pentax S3 bought new in 1961.....a camera I trust and took it to Ibiza as a backup camera to my Canon T70 (needs batteries) and some shots with the S3 and Flek 35mm f2.4 are posted here.
That whole generation of Pentax cameras really are the bee's knees... I've had the opportunity to pick one up several times but just can't justify it (already have a K1000, MX, as well as an army's worth of other cameras) :bang:
... I had to pass on a minty Spotmatic F + 55mm f/1.8 just because I had too many cameras and I couldn't justify it...
You've forgotten a key pair of Pentax offerings, the ES and ESII, the first cameras to use an electronic shutter and offer aperture priority! They came out in 1972 and 1974 respectively and were built off of the SPF body as well, when the SMC Takumar M42 lenses with the open aperture metering lug were used then you could just set the aperture, focus and shoot. In some ways the Pentax ME was the closest K mount version although it lacked a manual mode (but on the ES/ESII the light meter didn't operate in manual mode anyway)
Yeah I know how you feel, I've nearly bought a spotty going for peanuts many times at boot sales but lucky I always think "your S3 is good enough for you so pass" :shrug:

Nope, sorry. Don't understand the question...
