How about making mercury cells available but with a BIG deposit, to be returned when the spent cell is turned into an authorized disposal center? Or the deposit could carry forward on the purchase of a new cell. Unless there is a hazard presented in the manufacturing process this might solve the problem.
They definitely lasted much longer than a zinc-air battery. In some cameras, they could last years.Was there something special about mercury batteries versus modern zinc-air, like super long useful life? I ask because I've always wondered why mercury batteries got located in odd places like film compartment (Rollei 35), under the reflex mirror (Nikomat EL) and so on.
You know, it's funny, I once encountered a mercury cell with some life left in it out in the wild... might not seem like much but remember I was probably born after the ban. It was in a pristine Sr-T 101b that I couldn't afford, or I would probably be treasuring both the camera and the cell to this day.Today, the sensible way to replace a mercury battery would be with a lithium primary cell with built-in regulator for 1.35V. Regulated lithium cells are fairly common, but at 1.5V to replace alkaline cells. No reason the regulator chips in them couldn't be adjusted (either in manufacture, or via component changes if they have an external calibration) to mercury cell level. They'd outlast zinc-air by years, likely be good for the same five years as a watch battery in most of the cameras that used mercury cells (they only ran the meter with the battery, current draw of a milliamp or two and some shut off when the camera wasn't in use).
.Minolta XD-11. Gone. Traded for X-700. Another dumb photography mistake I regret
Excellent lens from everything I've heard. I have experience with the Soviet clone, the Helios 44.I started with war-times Kine Exakta, followed by Exakta Varex IIa. Great system with biotar 58/2.0
Thank you! The lens is really good.Excellent lens from everything I've heard. I have experience with the Soviet clone, the Helios 44.
Do you find it gives swirly bokeh at mid-wide apertures?Thank you! The lens is really good.
Kind of. Honestly, I'm totally not a bokeh fan. So I prefer f/4.Do you find it gives swirly bokeh at mid-wide apertures?
It's funny, because I have a Zenit C from 56 or so and the viewfinder is bright enough to focus at f/8 in dim light and at f/16 in a well lit interior. I will say that with my Praktica F.X3 and my Rectaflex I agree with you though. Those have more or less been my early SLR's (also Prakica FX with no prism attachment) so I guess I don't have enough experience to say.Kind of. Honestly, I'm totally not a bokeh fan. So I prefer f/4.
I'd say, that for those old systems large aperture is more for focusing in dusk, as viewfinders were quite dark.
Hi, Bob. The same, but purchased in 1970.Nikkormat FTN purchased in 1973.
It is one of the best.Hi, Bob. The same, but purchased in 1970.
Agree completely. When I bought mine I could have bought a Nikon F for not much more. The 'mat has much better ergonomics, and that's why I got it.It is one of the best.
my firstÍLR was a 1978 Praktika,which I no longer have and which died within a week of new purchase. I still have the pictures I took with it of my now deceased parents!I wanted to start this thread because tomorrow I will be using a camera that is the same model as my first slr. In 1989 I was a much younger man stationed in Okinawa, Japan in the U.S Navy. I didn't know anything about cameras or photography, but a friend talked me into buying his Olympus OM88. It is an unusual camera in that it is a manual focus camera that uses a motor to manually focus. Olympus called it power focus. It actually works very well, but takes some getting used to. I ended up shooting many rolls of film with it. In its standard form, it is a Program mode only, but you could buy a manual adapter to give aperture priority and manual exposure. I sold the camera a few years later when I bought another slr, but I kind of had an attachment to the Oly. A year or two ago, I found one at a thrift store for $10. I wrote about it in another post a couple days ago while talking about cameras I had owned before, and bought a second time. I loaded some black and white film in it tonight and will take it out tomorrow. My son, who is 12, will be going along and I will let him take some photos with it. He actually has an appreciation for the older equipment. By using the camera, I will create new memories while bringing back old ones. Not a bad way to spend a day.
