At last: open-aperture metering on a Pentax Spotmatic.
It’s not like stop-down metering is hard. It’s just an extra step, and a quick one: flip the switch. Yet to be free of it! Exposure information in the viewfinder at all times! This feeling of ease makes the Spotmatic F more compelling than any stop-down Spotmatic that preceded it.
Introduced in 1973, the Spotmatic F retained the original 1964 Spotmatic’s chassis. I expect the works are the same, too, except for changes enabling open-aperture metering. To power that meter the SPF got a bigger, more powerful battery: the dreaded, banned PX625 mercury cell. (Earlier Spotmatics used a battery that isn’t made anymore, though other special-order batteries can be adapted to fit.) But that’s not all bad, as highly available alkaline 625 cells fit and work fine despite delivering a little less juice (0.2 volts, to be precise) because Pentax added a bridge circuit to adjust voltage. It’s the only Spotmatic so equipped.
Well-known Pentax repairman Eric Hendrickson cleaned, lubed, and adjusted this SPF, so it works like new. And it may well have been essentially new, serving briefly as a sales demonstrator before falling into the hands of a Pentax employee who kept it without, it seems, ever using it.
The SPF is a 35mm SLR with a cloth focal-plane shutter that operates from 1 to 1/1000 sec., with flash sync at 1/60 sec. The SPF takes M42 screw-mount lenses, but open-aperture metering works only with SMC Takumar and Super-Multi-Coated Takumar lenses, which have a pin that lets the camera read the selected aperture. With those lenses, the stop-down lever (on the right of the lens barrel) provides depth-of-field preview.
The SPF meters through the lens using a CdS cell and a match-needle system in the viewfinder; it accepts films from ISO 20 to 3200. There’s no on/off switch, but at and below 2 EV the meter deactivates. Keeping the lens capped effectively turns the camera off.
The focusing screen includes a microprism patch. You twist the focus ring until everything looks sharp and the patch stops shimmering. The older I get the harder it is to see the shimmer, and so I prefer split-image focusing screens. This is the only serious thing I wish were different about the SPF, because otherwise mine is just a joy to shoot.
This SPF came to me with a 35mm f/3.5 Super-Multi-Coated Takumar lens. I love 35mm for everyday walking-around photography! Confident in my just-serviced camera I skipped over the inexpensive films with which I normally test cameras and loaded a roll of Ektar.
I took the SPF to Nashville, Indiana, where I attended a conference. My day was pretty packed, but I slipped away at lunch for some photography.
35mm lenses are just made for walking around and capturing scenery, of which there is plenty in Nashville. And this Takumar is sharp and renders color well.
Downtown Nashville is all little shops and restaurants. It’s a fun day out, easily reached from Indianapolis.
Nooks and crannies throughout Nashville provide plenty of interesting subjects.
On a sunnier day I visited the cemetery near my house. This monument went up in the last year or so but I’ve already shot it many times. The Ektar handled the brown well.
But wait…what’s that? Up there, in the trees? A little bokeh?
Yes, and it’s interesting bokeh, a constellation of little points. If only the subject (those leaves) was more interesting.
I walked through the neighborhood one afternoon with the SPF. This isn’t a neighborhood of picket fences, this one neighbor notwithstanding.
Another neighbor recently started parking this mid-1970s Ford Thunderbird curbside. It’s not plated. In a tonier neighborhood the HOA would be all over this Bird’s owner like stink on a garbage truck. Here, we have no HOA. His car can sit there for as long as it wants.
A lonesome highway makes a pretty good subject.

I waited until the end to say that the Spotmatic F is essentially the same camera as the 1976 Pentax K1000, except the K1000 uses the then-new K bayonet lens mount. Every other SPF review says that up front and I didn’t want to be tiresome. But I’m mentioning it now because I’ve owned a few K1000s, fine and competent cameras the lot. But I experienced real joy shooting this SPF, a feeling I’ve found elusive with any K1000.
Perhaps some of that joy comes from my SPF’s like-new condition. Buttery operation never fails to impress. But most of it comes from an indescribable quality, something special that got lost in the K-mount translation. If you know your way around apertures and shutter speeds and want to break into film SLRs, just get a Spotmatic F. Pair it with the astonishing 55mm f/1.8 SMC Takumar lens and you’ll never fail to have great fun.
