The readily available silver oxide variety will provide stable output and long service life.
Armchair theorizing aside, I suggest you swallow your pride and actually try one in your SPII.
If it matters I am an experienced professional electronic technician, working in the field for more than 25 years.

I think you need to read my posts carefully before posting your reply, instead of picking bits out of context.
I have no need to swallow my pride, as my findings are correct.
Its time to move on, there is no point in continuing this as you have not posted any sound evidence, regarding the performance of various battery/cell types, other than going around in circles, making reference to the, Sliver Oxide cell.
Others reading through this thread can draw their own conclusions.
Take care, and carry on using the battery/cell you are happy with.

Good question John, I always assuned that any M42 lens could be used on any camera, pentax or otherwise.
I do know that some lenses that have a larger 'pin' can get jammed but...
... Kris?

Mustn't forget the Zenits, or folders, or...

All Spotmatics are fully compatible with the 50mm f1.4 lens. It's only the S1a that needs to have the right colour R on the rewind crank.
Cameras earlier than the S1a should not be used with the f1.4 lens.
Best regards, John

It's worth noting some exceptions to the total compatibility.
The instruction books for the ES and ESII apparently warn against using 50mm f1.4 and 55mm f1.8 Super takumar lenses that have counter-clockwise operating diaphragm rings. See page 113 of The Asahi Pentax Screw Mount Guide for fuller details.
The f1.4 lens mentioned was redesigned from 8 to 7 elements and the same book reports an improvement in image quality as a result.

I've just acquired a SMC Takumar 50mm f/1.4 but haven't had a chance to try it out yet. I also have one of the late Auto Taks that looks the same as the early Super Taks with the counter-clockwise ring so I'll avoid using that on my ES/ESII.
Now to go and finish off my roll for "Roll in a Day" day before the light finally dies.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

If you are a Pentax purist, opt for the Spotmatic 1000, a genuine Spotmatic without a hot shoe and unchanged contour, this model brought to the end the era of the screwmount.

Hi Oso,
In the end I went for an SP1000, since added to with an SPII (bought because it came with a SMC-Tak 50mm f/1.4 lens) & SP (bought because it came with a Super-Tak 35mm f/3.5).
An un-scientific film test with an AG3 battery in the SP has shown the metering with this battery to be accurate enough for my working methods (usually metering off a mid-tone). As the cameras was new to me I checked the reading against my Sekonic L408B - slightly under, first, then went out shooting using only the camera. None of the resulting shots were badly exposed.
Photo sets from these and other recent 'first rolls' are here: link

Hi John,
Good to know that you have made your choice, you will be delighted with the smoothness and simplicity of its operation, especially with a working meter, Regards

I have an SP1000 and it does seem nice. I haven't finished the first roll through it yet so no results so far. I hadn't realised that it would stop the lens down when metering, which makes it difficult to use. With the Tak 35mm f/3.5 it's almost impossible to focus.

I'm using either Super-Tak or SMC-Tak lenses with the lens switch in 'Auto'. I usually focus before (or after) metering. You can push the meter switch back down as the body will stop the lens down automatically when taking the shot. I'm not sure if this works on Auto-tak lenses?

I too like the simplicity of the SP1000. It's my only screwmount body.
I never use self-timer, and it's easy to find the right size battery.
Another benefit is that some are ten years newer than the original SP.
