Field Camera Considerations if you want to shoot in low light stick to 35mm, if you want narrow dof don't worry about how slow MF or LF lenses are, they still have narrower dof than 35mm. 35mm equivalent of medium format. With the conversion factor of .79 (the magic number to figure out the 35mm equivalent focal length with this guy) that leaves me with a zoom of 35–67mm zoom. Wide angle lenses The 90mm lens is the most popular and versatile 4x5 wide angle lens, useful for a wide range of subjects from capturing vast landscapes, and both architectural and table top subjects. Even 6x4.5, the smallest medium format size, showed smoother tonality and a large jump in resolution when compared to 35mm. And when compared against the 35mm diagonal of 43mm, one gets and ratio of 1.6. this was even more so for those who used various large format cameras and lenses. That means that you should have roughly equivalent depth of field at f/2.8 on the Pentax and around f/2 on the Nikon. I've got a 121mm for 4x5 and it feels the same or like a 35mm lens on a 35mm camera to me. Now let's look at the column of the equivalent 35 mm focal length at 4:3. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. That’s about as close as I can get them to being the … Centre Performance. when people used Medium format and 35mm cameras, no one talked about the medium format equivalent lens. E.g. More articles on using vintage lenses / classic lenses . The term 35mm equivalent focal length is a comparison of the field of view seen through a digital camera lens compared to the field of view produced by the older 35mm … In photography, the 35 mm equivalent focal length is a measure that indicates the angle of view of a particular combination of a camera lens and film or sensor size.The term is useful because most photographers experienced with interchangeable lenses are most familiar with the 35 mm film format.. On any 35 mm film camera, a 28 mm lens is a wide-angle lens, and a 200 mm lens is a long-focus lens. I wanted a lens equal to my 25mm Zeiss lens on my old 35mm camera. ... they are taking completely different pictures. For example, 150mm lenses are often considered as portrait lenses in medium format and the aspect ratio of 4:3 is also very popular with portraits. Once upon a time most all the film cameras with interchangable lenses used 35mm film - it was by far the most popular medium for still photography. This means there will be lenses which cover a range of focal distances from 23 mm (equivalent to 18mm in the 35mm film format) to 350 mm (equivalent to 277mm in the 35mm film format). Compared to 35mm, medium format uses 3~4 times as much film surface. FUJINON GF 30mm F3.5 R WR: A wide-angle, prime lens. The high resolution MF lens avoids the "busy" or false details when it matches the sensor's resolution. In digital photography, the image sensor format is the shape and size of the image sensor.. The aspect ratios of 6x6 format (1:1) and 35 format (1:1.5) differ considerably, and an answer will depend on what aspect is used in the comparison. The Summilux does better than expected wide open, given its diminutive size and large F1.4 aperture. Exactly what I said earlier. In 8x10 format, the 200mm is equivalent to the 90mm in 4x5 for a basic wide angle. 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 Hasselblad XCD 35-75mm f/3.5-4.5 is just shy of being a medium format version of a standard 24-70mm zoom, with an equivalent 27.65-59.25mm focal range. For the full-frame Nikon and Pentax medium-format, that factor is about 1.4× (if you crop the wider 3:2 Nikon frame to get an equivalent image). This wide angle 30mm lens is an equivalent 24mm focal length in the 35mm film format. The 800mm on the medium format system will give us the equivalent of a 47mm lens on a 35mm system. A side-note about apertures in medium-format work. Re: ?medium format vs 35mm(lens equivalent)?? When I share images from the Summilux, I often get asked if they’re from the GFX. This gives the X1D a versatile multi-purpose optic, and effectively an everyday lens if you'd like to use your Hasselblad as as a walkabout camera. For a simplified discussion of image sensors see image sensor.. Fujifilm has announced development of two new lenses for the GFX medium format system. @RustyBug: the evenness is right discovery of MF lens on 35mm, it gives the natural , calm and not tension look. 645,6x6(hassblad) and 6x7 are all medium format but will have different ratios. When you compare lenses of equivalent angle of view, rather, the DoF does indeed get shallower with the larger format. Medium format lenses are interchangeable lenses for medium format cameras using 120 and 220 film, or which have similarly-sized digital sensors. with larger formats at least you have movements to compensate for the excessively narrow dof. It will still be a 150mm f4 lens on a 35mm sensor. From that you can calculate other focal lengths. This will give us a sense of the angle of view that the lens covers. 100mm? 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. Medium Format TO 35mm equivalent (divide by … While the lenses are generally slower, the depth of field is generally more pleasant with some lenses, offering a full frame equivalent of f/1.2-1.4 maximum aperture. - Schneider Kreuznach 35mm f/3.5 Lens with 89 degree angle of view on digital 645 medium format (approximately equivalent to a 22mm lens in 135 terms) The 101 megapixel Phase One back has a 2.5x sensor area advantage over the a7R Mk II's 645 format focal length vs 35mm lenses. Similarly, a 12-35mm lens provides a focal range equivalent to 24-70mm lens on the same camera. Well, it was basically the same story as Large Format vs Medium Format, or Medium Format vs 35mm Film – the larger you go, the more expensive it gets to manufacture gear. It requires a little cropping with both, medium and 35mm format. Of course, the FUJINON GF 80mm F1.7 creates the most excitement among photographers.

Medium format lenses converted on 35mm digitals. Fujifilm in […] Now, for those who like the 35mm format in those proportions then this is a correct comparison. This allows for better tonality (smoother gradations), finer detail, and less apparent grain. Right where I … Lens and Camera Systems. In reply to Serge88 • Jun 17, 2004 Also, be aware the medium format is used to describe 120 roll film. An equivalent lens on 4x5 would be half that at 125mm. When we calculate the comparative focal lengths between medium format lenses and that for 35mm, the diagonal of the frame / negative is measured. medium format is where people really start asking for more dof instead of less. 35mm is a “normal” lens. It is often asked, perhaps because there is no single answer. The field of view will be narrower than what you are used to on medium format, you can work out the equivalent "focal length" from the ratio of the lengths of the film/sensor. Medium Format All-In-One: medium format digital cameras with built-in sensors, like the Fujifilm GFX, Pentax 645, and Hasselblad X1D systems.
