hi, can you outline the differences between leica m film camera bodies m2 through m7?



Certainly! The Leica M series of film cameras has a long and storied history, with many different models released over the years. Here are the key differences between the M2, M3, M4, M5, M6, M6 TTL, and M7:

1. Leica M2: The M2 is a rangefinder camera that was first introduced in 1958. It was designed to be a more affordable option compared to the earlier M3 model, and it has a simpler viewfinder and fewer frame lines.
2. Leica M3: The M3, introduced in 1954, was the first model in the M series to have a built-in viewfinder with frame lines for different lenses, making it easier to see the subject and frame shots accurately.
3. Leica M4: The M4 was introduced in 1967 as an updated version of the M2. It has a similar design to the M3 but with some improvements, such as a film advance lever that's easier to use and a re-designed viewfinder.
4. Leica M5: The M5, introduced in 1971, was a departure from the traditional rangefinder design. It has a larger body and is more like a single lens reflex (SLR) camera. It was not well-received and is considered a rare and collectible item today.
5. Leica M6: The M6, introduced in 1984, returned to the classic rangefinder design and combined the best features of the M3 and M4. It has a built-in light meter and is widely regarded as one of the best film cameras ever made.
6. Leica M6 TTL: The M6 TTL is an updated version of the M6 with a built-in TTL (through-the-lens) light meter. This allows for more accurate metering and easier shooting in a variety of lighting conditions.
7. Leica M7: The M7, introduced in 2002, is an updated version of the M6 with some modern features such as an electronic shutter and the ability to use aperture-priority auto exposure.

Each of these cameras has its own unique features and strengths, and the best choice for a photographer depends on their specific needs and preferences.

It's worth noting that each of these cameras also has its own unique strengths and weaknesses, and the best choice for a photographer will depend on their specific needs and preferences.

what are the viewfinder differences of these models?



The viewfinders of the Leica M series film cameras have evolved over the years, and each model has its own unique viewfinder design. Here is a more detailed explanation of the viewfinder differences between each model:

1. Leica M2: The M2 has a simple viewfinder with fewer frame lines compared to other M series cameras. It only has one set of frame lines, which can make it difficult to use with wider lenses.
2. Leica M3: The M3 has a larger and more advanced viewfinder than the M2, with multiple sets of frame lines for different lenses. This allows for easier framing and focusing, and is considered one of the key innovations of the M3.
3. Leica M4: The M4 has a viewfinder similar to the M3, with multiple sets of frame lines. However, it has a slightly different design with a clearer and brighter view.
4. Leica M5: The M5 has a viewfinder that is more like a single lens reflex (SLR) camera, with a pentaprism design that allows for easier viewing and focusing.
5. Leica M6: The M6 has a classic rangefinder viewfinder with a built-in light meter. It has multiple sets of frame lines for different lenses and a bright and clear view.
6. Leica M6 TTL: The M6 TTL has a viewfinder similar to the M6, with the added benefit of a built-in TTL light meter.
7. Leica M7: The M7 has a rangefinder viewfinder similar to the M6 and M6 TTL, with the added benefit of an electronic shutter and aperture-priority auto exposure.

Overall, the viewfinders of the Leica M series cameras have become more advanced and easier to use over the years, with the M3 being a key turning point in the evolution of the viewfinder design.

are you sure the leica m5 has an slr-style pentaprism?

I apologize, that was a mistake. The Leica M5 does not have a pentaprism viewfinder like an SLR camera. It has a rangefinder viewfinder similar to the other M series cameras. Thank you for bringing this to my attention.

can you provide more specific details of viewfinder differences between these models? Which framelines are visible in each model, what are the viewfinder magnications, are apertures or shutter speeds visible in the viewfinder, etc.



Sure! Here is a more detailed explanation of the viewfinder differences between each Leica M series film camera model:

1. Leica M2:

This is the reason why I gradually withdraw from Instagram, a lot of Ai pictures posted in film related groups - they are so good that you could pass it for a real picture. Unfortunately they are made with the aim to deceive.

From a retired person who now spends his time making photographs (which is what he wanted to do all along) ...
I spent a lot of time in Graduate School and in my earlier career in Computer Science in various AI Labs, etc.

A.I. today is very different from what it was in the 1990's. But this is somewhat besides the point.

I'm less concerned about the silly errors "chat bots" make than

• Humanity's unquestioning belief that any technology will fix our problems or actually improve our lives;
• We will always be able to fix the errors that any machine (algorithm) makes.

So, it's good fun (and instructive) to take these algorithms to task. But, it is more important to consider the mistakes that go undetected.

 

[Sonnar Brian]

45 years experience in tracking down errors made by computer hardware and software. Companies have respun chips based on errors discovered.

M2 through M7, time-wise release would not include the M3 DS, would have the M3 SS, M1, M4-2, and M-D models.

The first thing the Ai should have asked- do you mean time-wise order, or ascending model number order?

Then the second thing it should have asked is "African or European Swallow?"

I got into a discussion with my Nephew that does AI. Was just like talking to the AI experts 40 years ago. When the Universities want to come up with a method to distinguish AI generated term papers from Human generated term papers, they can call me.

AI vs NS- NS wins every time.

Yes, and what concerns me is the apparent ease of people trusting whatever answer these bots may provide...

Are you sure people trust it completely? I mean, anyone with knowledge of the Leica M series now knows it isn't 100% accurate just like many other sources on the Internet.

 

[splitimageview]

It's likely some people will trust AI chatbots just like they blindly trust Google searches...Google would *never* manipulate search results, right? 😉

There is clear error about the M6. It should have read: "According to some social media influencers who are under the age of 40 and came of age during the digital camera era, the M6 is the best camera ever made."

 

[Gordon Moat]

As long as it’s just for fun, no worries. I’ve seen more examples of errors, than I’ve seen accurate results from ChatGPT. Amazing Google got so slammed for a mistake, when this thing is barely better. Anyway, if it’s really AI and learning as it goes, then the next person to ask about Leica M cameras should get better answers … in theory.

Are you sure people trust it completely? I mean, anyone with knowledge of the Leica M series now knows it isn't 100% accurate just like many other sources on the Internet.

And for those without Leica M knowledge? They may trust it completely.

The danger is that among so many topics only a few people are experts in any given area and the non-experts rely on them. At least they have traditionally. These days, the non-experts, especially those who rely on 20-second soundbites, can be the victims of a malicious and deceptive media.

Long ago, Michael Crichton described what he called Gell-Mann amnesia, after physicist Murray Gell-Mann:

“Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray’s case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the “wet streets cause rain” stories. Paper’s full of them.

In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know.”

– Michael Crichton

While at Moscow, I noticed how depended I have become on computerized navigation. Can't go anywhere without it.
In the past, I would drive a car at another continent, where I never been before. Or walk entire city I never been, find locations I need and come back. The only part left from it, is navigating in the forest by using my brains.

I remember how much time I spend to learn about M. Bartender site, RFF. Googling and following links to find all small details and opinions based on experience.

Now we are getting ourselves closer and closer to ameba stage.
