Fujifilm Superia X-tra 400 labeled “process before 2015-05”. I think I bought it new — it’s been in the freezer.

I recently acquired an old Canon Digital Rebel. I don’t have a charger yet so I haven’t used it but it has a CompactFlash card in it with images from July 2013 to August 2015.
Whoever the photographer is, I hope she sticks with it.
“Super” because the moon is close. “Blood” because of the eclipse. “Wolf” just because the January full moon is called a wolf moon. Some icy clouds so I wasn’t too optimistic but it turned out OK. The clock on my camera was about 20 minutes fast so the image time stamps are a little off. Images are shrunk to 1024 on the long side. Most with the Canon 60D & Sigma 18-250mm.
Back to the moon…
Original EOS 750 post at http://exit272.com/?p=1626
With a couple of exceptions, a camera with almost no control isn’t usually one I’d shoot with again. A fellow Youtuber asked if the 750 might gain aperture control using a speed booster. A Speed Booster™ (trademark of Metabones) isn’t available for a full frame camera and not for EOS to EOS. It would mess up the flange focal distance, losing infinity focus. That plus the anti-teleconverter aspect of the Speed Booster™ is more math than I want to tackle to figure out what it would do to the image.
I don’t have a speed booster but I do have lens adapters and old lenses. What will the 750 body do if it doesn’t find an EOS lens? Most modern DSLRs have a setting that allows the shutter to work without a lens being detected for macro tubes, bellows, etc., that break the lens-body communication link. This is a much older camera with no menus but it’s worth a shot.
First up, an M42 screw mount adapter. Nothing is passed through to the camera, it just puts the lens at the right distance from the film (or sensor) plane. A fresh battery, pop on the adapter, turn it on and…
No errors. Promising. In goes a dead roll of film (great for testing transport without wasting film) and the film pre-winds like it’s supposed to. The camera body lets me “take pictures”. The 750 is from 1988 and the EOS system had only been out about a year and a half so I guess it’s not that surprising that the firmware doesn’t have a routine for failing without a lens. ROM space used to be expensive.
I have some craptastic Photoworks film (a 24 exposure roll of “Use by 11/2004” ISO 200) so I’m good to go — just gambling some developer.
I used a Helios 44-2, a beautiful Soviet-era lens. It can be tedious but one of its quirks is what I want for this experiment. It doesn’t stop down automatically. You set the aperture and a separate ring swings between wide open (f/2 in this case) and your setting. This lets you focus on a nice bright image and then rotate the ring to stop down without having to look at the lens.
The 750 does full aperture metering. There is a separate, 6 zone light meter that reads the light with the lens wide open to get the exposure value (EV) so the camera can calculate the shutter/aperture combination.
How it works with an EOS lens. Anthropomorphizing and probably not completely accurate:
EOS body: Hey lens, what are you?
Lens: I’m a 50mm and I go from f/1.4 to f/22.
EB: Open up to 1.4 so the nice human can see what they’re doing.
[ Human 1/2 presses the shutter ]
EB: We’ve got focus lock. EV is just about zero. At 1/125 second I’m reading 2 stops over.
[ Human presses the shutter button the rest of the way ]
EB: Stop down to f/2.8.
[ f/2.8 is 2 stops dimmer (smaller) than f/1.4 ]
EB: Mirror up. Shutter fired. Mirror down. Advancing film. Open up to 1.4 so the nice human can see what they’re doing.
[ The 750 actually sucks the film back into the can rather than advancing but you get the idea ]
If the camera defaults to aperture priority, I’m golden. It’ll meter the scene and pick a shutter speed. If it does some shutter and aperture auto-exposure (AE) voodoo or shutter priority (Tv in Canon-speak), the experiment is toast. AE is bad because it can’t control the manual lens to match an aperture to its chosen shutter speed. Tv is bad because there is no feedback to tell me what shutter is chosen so I can pick an aperture.
Either I got lucky with a lot of exposure combinations or it does aperture priority. This also makes sense. When EOS was introduced, people who’d spent a fortune on the mechanical FD lenses screamed bloody murder. Canon even made FD to EOS converters with corrective lenses in them. With no way to communicate between the lens and the body, the only solution is to do aperture priority or manual (if the body lets you select the shutter speed).
Here’s my process. Turn the lens ring to wide open so the scene is bright and focus. Turn the ring to the f/stop I want and 1/2 press to turn on the meter.
Some macro shots. I’ve had the broken balsa plane and cicada wing forever. Add feathers and a seed and I have a theme. To get some depth of field, I had to stop way down. F/16 was too dark. Not bad exposure dark, just not an attractive image.
Next I tried a Nikon adapter. It has a “Dandelion” chip for focus confirmation but the 750 ignored it completely. It works with a Canon 60D DSLR so it’s probably the age of the 750’s firmware.
I’m not sure what’s up with the flower images (ignore the dust and cat hair — that’s a different issue entirely). It might be the film — the Photoworks stuff has lost a lot of speed from age and tends to make really crummy, thin negatives. It’s also possible my notes are wrong. According to my notes, the first one is at f/2.8 but it’s so thin the scanner had to boost the gain and made it ugly and grainy just to get something.
While writing this, it dawned on me that the bad images are under artificial light. Everything else is outside or on the sun porch. It fits the symptoms if the old film lost sensitivity to specific wavelengths.
The short answer (too late) is: The EOS 750 works well as an aperture priority camera with manual lenses.
Thanks to Salvador for asking a good question leading me to this fascinating journey.

Merry Christmas everyone!
There was a partially exposed roll in the Canon EOS 750 when I bought it in late 2014. I used the remainder of the roll as a test and, not expecting much, I had it processed at the drug store. Surprisingly, my shots came out pretty nice. There were also a few exposures from the previous owner.
Since the camera does pre-wind, these are probably in reverse-chronological order.
If you know these people or are these people, get a hold of me through the comments at my Youtube channel so I can send them a CD (kind of low-res since it’s drug store processing) and negatives.
I had to turn off comments on the blog after I was invaded by spam-bots.
This isn’t a great photo but it may be a great story. Obviously, it’s a begging sign, for want of a better term, but why wasn’t it finished? Was it abandoned for better cardboard? Did they have to flee? Did they get a ride? Did a magnanimous millionaire decide today is the day? We’ll probably never know.
Another story. The little guy had moved his bone beyond the reach of his chain. We moved it closer for him.
