My first SLR with a built in meter mine got lots of use about 275 rolls of film, lot of use with outside exposure. The meter uses a silver oxide cell not a mercury one.
The dual metering will require you to think about the lighting & which meter option you want to use.

There were times that Kodachrome was made in 120 film size.

I the 50's & 60's Kodak 35mm cameras had very good lenses but poor unreliable shutters. I is hard to find the cameras now days that have still workable shutters, or even shutters that can be cocked on many of the models. The complex ones had all kinds of ways to go bad, even the simple ones may not work right. The box cameras & low end Instamatics with single element plastic lenses can't take sharp pictures, low end 35mm cameras like the Kodak Pony could take very sharp pictures.
When Kodak resumed manufacture, or did it buy 35mm cameras from other manufactures with their labels on them
they had mechanical problems or even problems with plastic parts breaking. Which is sad because Kodak had been a major seller of plastic. But even with the simple (fixed focus) 35mm cameras they could take much better pictures than the junk 35mm cameras that many sold.

It takes 620 film. 120 film can be rolled onto 620 spools.

I don't think I will ever really know what happened. I will keep an eye on my future pictures and see if it happens again. Thanks to all who tried to help me figure this out



I am sorry for the late replay, I didn't read these posting until a few days ago. There were some strange answers, but I think a few answers hinted athow the pictures were made.
I have a camera that has a mode called digiwide that will put 2 pictures together in the camera.


This is may 2nd attempt to make a picture like the original post.





I could also put the 2 pictures together one on the top of the other.



And done as intended lining the ghost image in the viewfinder up for the 2 nd shot.

This is often the case and these allen wrench head bolts are quite often metric - it is important to have the proper size to keep from stripping/ruining it
Have you done a internet search about your specific problem and model of tripod. Often there is an answer.


Manfrotto - Bogen tripods are metric.
The 5/16" nut driver works because it is so close to 8
mm. If use need to replaced any bolts or nuts you will want to look for metric sizes to replace the lost ones.

The VR, OS or IS systems all move a lens element in the process of counteracting motion. When on a tripod there is no motion and these stabilization systems can cause burred images due to searching for movement to counter-act. Turn it off and you will never have an issue with it.
SOME newer lenses have a "tripod aware" feature in their VR systems, but do not expect it to be there unless you have read that your lens does have this feature in that lens' owners manual, always assume it does not have it.

I understand Pentax cameras turn the IS system (shake reduction) off if the IR remote control is used to release the
shutter.

After extensive analysis and creating an algorithm which accounts for all variables, the results came up as... a
"Butt Load".


A butt is a wine cask that holds 2 hogsheads or 126 US gallons. I think my slide negatives, CD's I saved digital files on, & prints would probably fill one hogshead barrel.

It is hard to find things in the US that are made in the Us.
I replaced by up stairs bathroom sink last year, over 98% of the content in dollar amount was not made in the US. Only some pipe pieces to connect the water pipes to the shut off valves under the sink were US made. Even the American Standard faucets were made in Mexico. The bowl, stone top & back splash were all made in China.

These look like the minicams of the 1940's & 1950's that took 16 exposures on 127 film (30x40mm). The Lomo cameras look like someone reworked the molds for one of these old bakelite cameras.

I know what anastigmat means, but how you double it is a mystery!

You have done a splendid job! I know that a modern closeup/macro is more practical, but that looks so much more fun! My wife thinks I am nuts, but you are a true enthusiast!


The lens probably has 2 groups each being a 3 element group cemented together, each group is a anastigmat, the lens should be symmetrical meaning the front & back groups are identical but pointed in opposite directions. It should be good for a closeup lens.

I am sorry, but I attached the wrong image for the Raw simultion to the previos post.
This is the correct one.

If you could zoom into the pixel level of a true raw file each pixel would be only one color some level of red, blue or green, there would be no white pixels.

"From HFB, One last question, How many pixels does a full frame 35mm sensor have?"
am surprised to see this question from some one skilled in digital technology. Pixels are not specific sizes. The number of pixel on a sensor varies with little relation to sensor size. Some point and shoot cameras have more sensors than APS and full frame SLRs. I simple cameras it's used as a marketing tool with no relation to image quality.

When it comes to lens quality the current sensors are getting better resolution than many of the older films. There is also an issue with the angle the light hitting the sensor at the edges. This showed up as a real problem with Leica digital range finder (no mirror) cameras with lenses that where close to the film. SLR lenses have been designed to be position further away from the focal plane and don't have this problem. When Leica had Kodak design the sensor for the rangefinder the edge angle was compensated in the design.

There was also a problem with the reflective nature of the digital sensor. Older lenses had shiny metal on the rear and paid little attention to coating rear elements. This could increase flare and reduce contrast.

I have a old Spiratone 12mm fisheye lens there is no way that the image quality on a digital camera will match what it can do on a film camera. On the other hand you will not see a difference with long lenses that were designed for film cameras.
