Pentax Spotmatic SP


Recommended Posts

<p>Over a year ago now I wrote asking for a recommendation for a M42 mount camera. I was planning to use lenses in this mount on a Canon 30D and thought it would be nice to have something that didn't need batteries that could also use the lenses that I picked up. I received a lot of responses and a lot of different recommendations and finally ended up with a $10 estate find. Engraved by it's previous owner it was obviously treasured and well cared for. Since I use my cameras the engraving didn't bother me and I snatched it up. I replaced the seals and the battery and took it out for a test drive. First the porn.</p><div>00aXYT-476787584.jpg.dfe1d7c2470250a244dab476a720a33e.jpg</div>

<p>And now the results. A quick walkabout to confirm the meter was registering after the new battery. A sand pile from the Highway repaving project in front of the house. </p><div>00aXYY-476793584.jpg.73a1a08e3d9f0b37a7e2baaf23517049.jpg</div>

<p>A couple more from the back yard. I love fresh salsa and when I finish the container while outside I' usually dump the remaining juices and seeds out in the yard. I don't know why this little fellow was such a surprise to me.</p><div>00aXYn-476801584.jpg.907c60fe9456b441acf36e505f53a050.jpg</div>

<p>Been waiting, worth the wait.</p>

<p>My first serious professional camera was a <a href="../classic-cameras-forum/00Y3Rk">Pentax H-2</a> and I still think that <em>form</em> (including the Spotmatics) is among the most <a href="00MgL8">beautiful</a> 35mm SLRs ever made.</p>

<p>Congratulations on your camera and post.</p>

<p>Very nice series. What battery did you use with the spotty? I know the original battery for them is a mercury cell. I have a Chinon CS that is designed for a mercury cell but works with a 625 alkaline cell if I lower the ASA dial by one speed. Then, I have a Minolta SRT201 that works fine with a 625 cell as is. That Rikenon lens looks interesting.<br>

As far as posting multiple pictures, when you find out how to do it, let me know. I haven't got it either.</p>

<p>Ah, the good ol' Spotty. Examples with working meters are getting harder to find, which is a pity since they're so nice to handle when all systems are go. There's a quiet quality about the Spotmatics that's hard to beat. Nice results, <strong>Lionel</strong>; beautiful smooth background in the thistle pic.</p>

<p>Spotmatic definitely uses a bridge circuit. Meter has two coils. One is in series with the CdS cell. The other is in series with the variable resistor that tells it the shutter speed/ASA combination in use. They are wired to push in opposite directions, when they push the same amount the meter needle is centered, and your exposure is consistent with the light coming through the stopped-down lens. So the exact battery voltage is quite non-critical, you just have to send the same voltage down each resistance leg to be accurate.</p>

<p>Yup, Frank, the shoe can be removed, but it leaves a useless and unsightly hole in the prism that mars the otherwise clean appearance of the OM-1.</p>

<p>Turned out the shoe "FIX" on the early OM hotshoes meant "20 years from now will need to be fixed repeatedly." The plastic deteriorated badly. By the late 1990s my OM accessory shoes were made of 90% superglue and epoxy.</p>
