You would need to calculate the image diagonal for any MF sensor that is not a Full Frame 645 and use that to calculate the focal length equivalent. Medium format refers to the size of your roll of film (or if you’re talking digital, it’s the size of the camera sensor). A 35mm lens at f/1.4 has a 25mm aperture. what i think he meant is , why with a 80mm on medium format, f2.8 subject 10feet, you get less DOF than a 80mm on a 35mm , f2.8 and subject at 10 feet.

The aperture determines how collimated the admitted rays are. To calculate the crop factor as it is generally defined, divide the diagonal of the 35mm "full frame" format by the diagonal of the format in question. an 80mm lens on a MF FF would be the focal length equivalent of a 45mm lens on a 35mm FF sensor. An f/2.8 lens is an f/2.8 lens regardless of the sensor or film size. The most startling incident in my life was the time I discovered myself to be a poet, which was in the year 1877.William McGonagall. The downside is that medium format cameras are bigger, heavier, more expensive, darker lenses (f/2.8 or f/4 is usually the largest aperture), and film-developing costs more. The crop factor is also used on the aperture to give us the maximum effective aperture equivalent on a full-frame camera. Well, it is (to paraphrase) not the size that counts, but what happens behind it. Compared to 35mm, medium format uses 3~4 times as much film surface. Here are the possible ways to compare. The Leica Q2 Monochrom is a version of the Gold Award-winning Q2 that only shoots images in black and white. Re: First DSLR,noise on darks, blowed highlights...

What’s the best camera for less than $1000? “Given the different format sizes between medium format and 35mm, we have different magnification, and this results in a difference of appearance of depth of field,” Taylor says. Anyway, hope this helps. Again, that's basic maths. In this buying guide we’ve rounded up all the current interchangeable lens cameras costing under $1000 and recommended the best. 2. compare results on screen - good for pixel peepers 3. compare prints and projected pictures - actually gives useful information for the photographer Bertrand on March 11, 2019 at 12:37 pm .

Here are the four videos of the four comparison tests: For the fourth test, Taylor set up a tabletop scene and compared the depth of field captured by the two cameras at various apertures. You can calculate the diagonal, if you know the width and height, with the Pythagorean theorem. ... You can only compare DoF by looking at aperture if you maintain the same sensor size. WRONG. (w/ 645D) / 42.5 deg. “The medium format image has a lot more bite and a lot more contrast, a lot more richness, but again it comes down to that smoothness of transition of tonal range that is afforded by the larger sensor,” Taylor concludes. The high resolution MF lens avoids the "busy" or false details when it matches the sensor's resolution. 35mm Film. Fast f/2.8 aperture for excellent depth-of-field control; Rounded diaphragm blades for creating soft bokeh at large aperture settings; Focal length equivalent to 71mm (in 35mm format) Weather-resistant and dustproof; Angle of view: 34 deg.

What are you actually trying to figure out? [CDATA[ How come am I trolling for this? Vaporware no more: the much-speculated-about Zeiss ZX1 has arrived. Crop Factors on Medium Format Cameras. Don't expect others to do all the work for you. “Medium format refers to the active image area, be it film or digital, with anything larger than the 24x36mm dimensions of 35mm film, also known as 35mm format, and smaller than the 4×5 inch, or large format, image area,” Hasselblad says. It's quite simple really. The lens aperture is usually specified as an f-number, the ratio of focal length to effective aperture diameter. @RustyBug: the evenness is right discovery of MF lens on 35mm, it gives the natural , calm and not tension look. Combining a 37MP full-frame sensor, minimalist controls and Lightroom Mobile built in, it's a refreshing – if a bit quirky – take on the smartphone-meets-camera concept. Larger sensors than full-frame, like medium format sensors, have a reverse crop factor. Lately, there has been a lot of talk about whether there is, in fact, a medium format look. 2.8 x .62 = 1.736, or 1.7 when rounded. Lenses designed for use on 35mm SLRs may be usable on bellows or extension tubes on a medium format camera, as at the greater distance from the film the projected image may be large enough to cover the frame fully. Review: Does the Canon Rebel T8i DSLR make sense in an increasingly mirrorless world? Sorry, no... as was pointed out in the first reply, the f-number of a lens is a property of the lens alone and does not change with film or sensor format. f/2.8 is f/2.8 Period.

If you're looking for a high-quality camera, you don't need to spend a ton of cash, nor do you need to buy the latest and greatest new product on the market.

If you really don't understand DOF then please go and read some of the suggestions you have been given. You need to specify whether you mean "focal length" equivalent which you can easily calculate or "Depth of Field" equivalent which opens up the same can of worms as the old FF vs Crop question on 35mm (please don't do that!!!). Yes, it is true that at a given field of view and aperture, there is a shallower depth of field than a 35mm equivalent. Mikehttp://www.pentaxphotogallery.com/artists/mikeward.

Sensor sizes currently have many possibilities, depending on their use, price point and desired portability. And when you view high-resolution scans of medium format vs. smaller formats, well, the differences can be striking. You can do that yourself for any other aperture you want to know. There is no "aperture equivalent" since it is purely a function of the lens and has no relevance to sensor size. Sep 16, 2010 6,656 5 76. Comparing sharpness of 35 mm vs 4x5, even a decades old, good quality LF lens that can be bought cheaply on ebay will beat the best 35 mm lens -- this is with the lenses used at their optimum apertures, which will be different, and for the same print size.
