The f/4.8 maximum aperture of the 24mm might seem comically small to folks used to f/1.4 lenses, but bear in mind that it’s a lot harder to make lenses to cover the massive imaging plane of medium format cameras, so compromises have to … Exactly what I said earlier. These cameras combine the advantages of digital back systems (like image quality) with a major positive of 35mm systems -- rock-solid reliability. Centre Performance. Note: For a quick understanding of numbers like 1/2.3, skip to table of sensor formats and sizes. When you compare lenses of equivalent angle of view, rather, the DoF does indeed get shallower with the larger format. Field Camera Considerations Now, for those who like the 35mm format in those proportions then this is a correct comparison. 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. The 800mm on the medium format system will give us the equivalent of a 47mm lens on a 35mm system. 100mm? Huw Evans. 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. 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. This will give us a sense of the angle of view that the lens covers. with larger formats at least you have movements to compensate for the excessively narrow dof. Fujifilm has announced development of two new lenses for the GFX medium format system. medium format is where people really start asking for more dof instead of less. When I share images from the Summilux, I often get asked if they’re from the GFX. Would a Pentax medium format lens with a max aperture of f4.0 let in more light than a Pentax 35mm lens at f4.0? More articles on using vintage lenses / classic lenses . 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. You can calculate the diagonal, if you know the width and height, with the Pythagorean theorem. Edit: Since I'm on the stupid questions roll: If I were to use a 50mm Pentacon 6 medium format lens on a Pentax K-x with the Pentacon 6 adapter, what full frame focal lens distance would it be equivalent to? Medium Format TO 35mm equivalent (divide by … 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 … Medium format lenses converted on 35mm digitals. 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. Medium format lenses are interchangeable lenses for medium format cameras using 120 and 220 film, or which have similarly-sized digital sensors. I think the lens’ good performance wide open is the reason people mistake it for medium format. An equivalent lens on 4x5 would be half that at 125mm. 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. That’s about as close as I can get them to being the … 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. Now let's look at the column of the equivalent 35 mm focal length at 4:3. In digital photography, the image sensor format is the shape and size of the image sensor.. This allows for better tonality (smoother gradations), finer detail, and less apparent grain. Medium format mirrorless systems are a great way to get into photography with a sensor that’s larger than a full frame 35mm sensor, so long as you can afford the higher price point. 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). 645 format focal length vs 35mm lenses. A side-note about apertures in medium-format work. In 8x10 format, the 200mm is equivalent to the 90mm in 4x5 for a basic wide angle. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. 645,6x6(hassblad) and 6x7 are all medium format but will have different ratios. 6x7. Right where I … You just learned the appropriate focal lengths for your cameras to suite your purpose. FUJINON GF 30mm F3.5 R WR: A wide-angle, prime lens. I use a 250mm on 8x10 and it feels like a 35mm lens to me on a 35mm camera. When we calculate the comparative focal lengths between medium format lenses and that for 35mm, the diagonal of the frame / negative is measured. And when compared against the 35mm diagonal of 43mm, one gets and ratio of 1.6. I've got a 121mm for 4x5 and it feels the same or like a 35mm lens on a 35mm camera to me. 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. Lens and Camera Systems. 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. - 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 It will still be a 150mm f4 lens on a 35mm sensor. Fujifilm in […] 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. Compared to 35mm, medium format uses 3~4 times as much film surface. 35mm equivalent of medium format. www.huwevans.freeuk.com . Even 6x4.5, the smallest medium format size, showed smoother tonality and a large jump in resolution when compared to 35mm. Leica 35MM Summilux F1.4 FLE. 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. 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. From that you can calculate other focal lengths. The diagonal of which is 67.30mm making the standard lens as 65mm possibly 70mm. 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). The Summilux does better than expected wide open, given its diminutive size and large F1.4 aperture. A very frequently asked question is one about the 35 mm format focal length equivalent of the lenses used on Hasselblad's 6x6 format. E.g. You may have come across the term "35mm equivalent" when viewing information about digital camera lenses and their focal lengths.
