That's not correct. Look at this picture: The green rectangle is a 36x24 sensor. The green circle, which has a diameter of 43.3mm, is the minimal light spot needed for that size. The blue square is 36x36 sensor. The blue circle, which has a diameter of 50.9mm, is the minimal light spot needed for that size. As you can see a lens suitable for 36x24 does not ...

Is it possible and why it has not been done yet ? Not necessarily. A 24x36mm sensor will easily fit in an image circle that's too small for a 36x36mm sensor. Specifically, a 24x36mm sensor requires a minimum diameter of about 44mm to cover the sensor. A 36x36mm sensor would require an image circle of about 51mm diameter. A square sensor is certainly ...

There's quite a bit of difference, actually. Size of the Negative Medium format is a somewhat encompassing term. When one talks about 35mm (135 film), it's most often a camera that shoots a 36mmx24mm frame. There have been specialty cameras that use the 135 format to shoot other sizes, but most 135 cameras shoot this fairly standard sized frame. Medium ...

The rangefinder only supports framing (with parallax), the dual-lens reflex also supports focussing. This assumes that both lenses move in tandem, and that the picture through the upper lens is viewed on ground glass.

Online, your simplest and easiest options are to google on the name of the camera and "user manual", or to find out if the manufacturer still exists and has a website and look through their support/downloads sections and/or to contact them directly. Or you may want to start scouring eBay. Ephemera, such as manuals, are often sold to collectors as well as ...

The "telecompressor" you mentioned is a focal reducer, a device that concentrates the image in order to project it onto a smaller sensor. This approach reduces the backfocus distance (the distance from the back of the lens to the sensor). So it only works on mirrorless cameras using lenses designed for DSLRs (which have sufficient backfocus distance to make ...

I don't think you can determine what specific camera left the observed notches, because it's not a feature or property of the camera's construction. Rather, it's a part of the construction of the film holder. The image you link to is a print of an uncut negative. The notches are simply the part of the film that is left visible by the rails of the film ...

Theoretically if you keep the size of the entrance pupil and field of view the same then you will capture the same total amount of light regardless of the format. If your medium format sensor in 1.6 times larger (which is the upper end available today, the Leica S2 you mention is only 1.25 times larger), then to match your 35mm DSLR and 85mm f/1.2 lens ...

The sensors could be made to a square format (though the current diameter would not accommodate 36x36mm, it would need to be about 30mm) if there was a demand for it. But by that logic the question we may actually need to be answering is why aren't sensors circular given that lenses present a circular image? There were some attempts at circular sensors in ...

Some reasons: 1) Sharpness. 2) Size... If you have a 80Mpx image you need point 1 first. 3) Dynamic range improved dynamic range seems unimportant using controlled lighting Seems unimportant..., unless you need it. If you are taking a photo of a well known actor or actress, you want to squish the more information you can get from your image. A medium ...

Historically, product photos were taken with large format cameras so that perspective distortions could be corrected by bending the film plane with respect to the image plane. Nowadays we can easily correct for keystone distortions using software. Additionally, distortion correction requires enormous depth of field. Apertures of f32 and smaller also mean ...

Once one understands the advantages of a medium format camera it becomes obvious that there are situations that such a camera would make sense. It is unlikely that a client will specifically request such a camera, but it is possible that the needs require resolution, sharpness, dynamic range, and contrast that you may only be able to achieve with a medium ...

Of course there are some cons. If there weren't, everybody would do it all the time. :-) For some obvious cons, consider that a medium format lens will almost always be: larger heavier more expensive, and lower resolution ...than a lens built specifically for 35mm. As for the specific questions you asked: Can the greater field of view be a source of ...

Assuming your end product is a digital image (i.e. not a paper print) the steps of your workflow are simple: develop the film scan the images As for developing: it is important to consider Black & White and Color films as separate realms. black & white film is on one hand comparatively easy to develop - you need just three baths (developer / ...

I have a Rolleiflex 3.5F and I love it. It's so much fun to use, and results are always pleasing. Strangers are always interested in it, and are often happy to pose for photographs. Try that with a cellphone! According to the photo.stackexchange.com Help section, "questions should be reasonably scoped. If you can imagine an entire book that answers your ...

The Hasselblad 500C/M is a single lens "reflex" camera. That means that the image you see in the viewfinder is a through-the-lens view reflected to the viewscreen by a mirror. When you adjust the angle of view by changing the lens focal length, this change is translated to the viewfinder because what is projected into the viewscreen is coming through the ...

Thought I could weigh in on this subject. As an amateur, you and I may tend to go for the cheaper option. 35mm can be reached (initially) cheaper than medium format, without a doubt. My first film camera (Canonet QL19) cost $25 and I still use it all the time! It's my favorite camera. I have however noticed that developing can get expensive, especially ...

The main advantage these days is that most SLRs and rangefinders are typically for 35mm film, while TLRs typically use 120 film (medium format). Bigger film is much like a bigger sensor: more image data, higher resolution, etc. But the waist-level viewfinder also allows you street shoot a little more stealthily, and, as with view cameras (the kind with ...

Crop factor is a characteristic of the camera, not the lens. A 50mm lens is 50mm no matter what you attach it to. The bigger or smaller sensor is what leads to crop factor, which is the ratio of the area of a full frame sensor to the area of the sensor in question. Smaller sensors will have a ratio > 1, and medium format sensors (or other larger sensors) ...

I do not know what are the values the app is giving you. But the exposure readings are meant to be independent of sensor or film size. The F-number is the one dealing directly with the film size because the number is taking into account both the aperture (the amount of light) and the distance to the film plane, which has to cover the film plane, your frame.

It really depends on how you define image quality. Currently medium format digital cameras and backs off higher resolution (up to 80 megapixels) than 35mm cameras (up to 36 megapixels). In good light with equally "good" lenses more megapixels will result in a sharper picture. Additionally a larger format makes it easier to design sharper lenses (in terms ...

I'm 10 years late here but... in case this helps anyone more generally: Most medium-format cameras from Zenza Bronica would tick most (some even all) of the boxes on your list, and they also benefit from being generally cheaper (and having cheaper lenses) than the competition. Here's a non-exhaustive rundown: Bronica S2(a): early, all-mechanical, nominally ...

(1) Irrespective of the lenses used (Zeiss Otus for example), a Nikon 810 or Canon 5ds can't produce detail that the sensor can't pickup to begin with. A small sensor can't resolve the detail that a larger sensor can even if you put an average kit lens on a 300mp camera. You'll get more detail with the kit lens and larger sensor compared to a great lens on ...

Can I use my full frame digital camera to set up the exposure for my medium format film camera? Yes, you can use a digital camera to take test shots in much the same way pros used Polaroid backs for many years. Just keep in mind that both film and digital have some leeway with regard to ISO. Many digital cameras can be 1/2 stop or more less sensitive than ...

I think the biggest difference is going to be in camera choices. Medium format is mostly what twin-lens reflex (TLR) cameras use. Both formats are supported by rangefinders and single-lens reflex (SLR) cameras, but with TLRs you're mostly shooting square medium format (120/220), not 35mm (135).

You have to look at things in context. At the time (pre 1930's), photographic options were quite varied but all similar in design. You used some sort of external focusing aid not (Kodak pocket camera) or set up a rather large camera that projected the image onto ground glass, which would then be swapped for film. The photographic industry has always been ...
