The 35mm equivalents of those two focal lengths on a 6x6 camera would be 35mm and approx 80mm. On top of that very few sizes of standard B & W printing papers are of the same proportions. Actual . mm format focal lengths will be longer accordingly. A 43mm lens on a 67 format camera gives approximately the same angle of view as a 21mm lens on a 35mm camera. 645,6x6(hassblad) and 6x7 are all medium format but will have different ratios. Simply input your focal length, sensor size, and max aperture and we'll give you what the 35mm equivalent is of that configuration. I believe 100mm is considered "normal" for 6x9. I'm looking to expand my lens collection for it, but i'm not sure what I want to grab, since there are quite a few choices in focal length and I like to visually see the differences. The theoretical focal length of a Zeiss (Kyocera/Contax) 50mm f1.7 is actually 51.9mm making 51.64mm even closer to 90mm in medium format terms. Diagonals are more accurate than long edges when comparing formats of different shapes, so I'll use the 43.2mm diagonal of 35mm vs. the 79.2mm diagonal of the 56mm x 56mm—aka 6x6—'Blad. Here are the possible ways to compare. The 6x4.5 format is a little For example, an 180mm lens on a 4x5 camera would have an equivalent focal length of approximately 54mm in 35mm terms and for 8x10 it would be 27mm. the (horizontal) equivalence is true. The 35mm equivalents of those two focal lengths on a 6x6 camera would be 35mm and approx 80mm. The 35mm equivalent lens is shown for reference. You can pick up a used camera for a few bucks, and they're so ubiquitous that some people just give them away. The 35mm film gate size used was 24mm x 36mm. "Approximately" is the key word. Here are the possible ways to compare. frame is taller than the 35 mm format frame, yet less wide. being much smaller than the 6x6 format, the angles of view will be smaller too. Angle of View Chart . focal length of (43.2mm/79.2mm * 150mm) = 82mm and an equivalent … 35mm is by far the cheapest way to go when getting into shooting film. Pentax Zoom Normal-Telephoto 80-160mm f/4.5 Autofocus Lens for 645N. As a result the table only gives an approximation of the equivalent 35 mm format focal lengths. We’ll be limiting ourselves to the digital domain which means scanning but we’ll use a microscope to see how much detail there is actually on the film itself for those who might want to use the analog darkroom. I heard that F2.8 is F1.4 in 35mm. focal length of (43.2mm/79.2mm * 150mm) = 82mm and an equivalent … What killed the 6x6 systems for me was that I wanted a long (>300 mm, ~180 mm equivalent on 35 mm) apochromatic tele. 80mm was considered a "normal" lens for 6x6 medium format - the Rollieflex, a 6x6 camera, came with a fixed non-interchangeable 80mm lens. With medium format 6x6 film you get 56 x 56 = 3,136 sq mm, which is 282 megapixel. The actual focal lengths differ, Promo Financing * Add to Cart. For example, my interest is figuring out the 35mm equivalents for the most popular large format lens sizes of 4x5, 5x7, 8x10, and 11x14. The (vertical) equivalence is true. Making the 645 format the same proportions as 35mm is roughly in agreement with the manufacturers. vertical angles of view are equal (blue outline = 6x4.5 format). On true 645, the DOF is equivalent to f/1.7 on 35mm. $749 95. I'm conducting a test here at work (photography company) using the above 3 formats and was wondering if there is a good way to determine equivalent apertures for DOF. 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. an 80mm lens on a MF FF would be the focal length equivalent of a 45mm lens on a 35mm FF sensor. by Ken Williams on 27 June 2011CRU Issue 15. Regarding exposure, nothing changes; f/2.8 is f/2.8. https://petapixel.com/2014/12/18/comparing-image-quality-film-digital Hasselblad's 6x6 format. So F2.8 in true 645 is F1.7 right? Also called 6x6, 2-1/4 x 2-1/4" or simply "Two and a Quarter." 6X6 4. Feel free to … lengths. A detailed comparison. ... in proportion to the format sizes. 1. count lines - should give us the absolute peak resolution of the film files. The aspect ratio is the same as that of the original 6x6 format, so the same considerations apply. Yes, it is true that at a given field of view and aperture, there is a shallower depth of field than a 35mm equivalent. It was replaced in 1999 for journalism use by digital with the introduction of the Nikon D1. It is also interesting to note that a 50mm lens is based on a 2” lens which is a hint longer in focal length. As Figure 1 shows, the different aspect ratios of both formats lead to a rather different framing: the 6x6 I also wasn't a big fan of the 5 blade straight aperture of the Hasselblad V lenses. In Figure 1, 6x6 format (black outline) and 35 mm format (red outline) frames that have the same size diagonal For example, a 6×6 camera has a crop factor of .55. 2. compare results on screen - good for pixel peepers 3. compare prints and projected pictures - actually gives useful information for the photographer A very frequently asked question is one about the 35 mm format focal length equivalent of the lenses used on Hasselblad's 6x6 format. Though It obviously is very easy to crop the larger frame to produce an image exactly the same as that produced inside bit taller than the 35 mm format. Focal . Actual . Focal . ( "Diag" in the table above.) 10x12. Using the long side angle of view the figure is 0.56. 110 Film Consequently, the spread in equivalent focal lengths depending on what We can also use that crop factor to determine the 35mm-equivalent … Copyright 2009 - Q.G. And so I settled on the Mamiya RZ67. Let’s look at leaving the formats as they are. Key Features. It depends on how you calculate it. If you want to be awkward then 42mm x 56mm IS the same proportions rather than 41.5mm x 56mm. are superimposed. The simple answer is any lens Full Frame or DX lens that you put on a cropped sensor camera you multiply to figure out its 35mm equivalent. Actual image size 56 x 56 mm. 5x7 6x17. Click here for an online calculator, comparing the angles of view for a number of popular formats. the same (Figure 3), the difference in aspect ratio leads to a 1.5 times larger vertical angle of view on 6x6 format. 35mm is the world's most popular film format. Older manual lenses can be had for pennies on the dollar of their original price as well. Another option would be to select lenses so that their vertical angles of view 12 Mos. On a 35mm-based body like my Sony A7 III, a 105mm lens is a telephoto. 645 6x6. 120 film shot on a 6x6 camera is 56mm x 56mm ... (and obviously same focal length 28mm, this being, i assume the 35mm equivalent in respect to the sensor size) the sigma had a quite noticealble smaller DoF!And in the article, they were saying this had to do with the bigger sensor the sigma has. Figures 4 and 5 show the difference in framing when lenses are chosen so that either the horizontal or If I have missed anything, please contact me and let me know. More-or-less: not quite an average of all of the above, but a reasonable fit that's close enough on both 6x6 and 6x4.5 to a 35mm focal length that is actually used. B&H # 1788938 . 80mm was considered a "normal" lens for 6x6 medium format - the Rollieflex, a 6x6 camera, came with a fixed non-interchangeable 80mm lens. The frame number for this format is printed at the bottom of the frame. format in 1956, 6x6 is not the only Hasselblad film format. What is Equivalent is the size of the Field of View produced by the two combinations of lenses and sensors. A subject just fitting inside the 35 mm frame horizontally will not fit inside the 6x6 frame, and conversely, a There are other "medium format" formats - 4.5x6, 6x7, 6x9 for example. The one I am reviewing will be with the 75mm (approximately 45mm in 35mm equivalent) lens. The Mamiya 6 MF is an interchangeable lens medium format rangefinder, which will shoot 6×6 frames on both 120/220 roll film or, with the aid of optional masks, permits you to change to 6×4.5 medium format and panoramic format 35mm film. the same focal length. This means that 80mm is about right or maybe 75mm. The "normal" focal length of a 35mm camera is 43mm. The ratio is 6 x 6 is 1.8 x 35mm focal length. So the calculation now alters as the diagonal of a 32mm x 24mm is exactly 40mm. Regarding exposure, nothing changes; f/2.8 is f/2.8. On true 645, the DOF is equivalent to f/1.7 on 35mm. Framing in both formats is equivalent only in the rare case that subjects have to be framed diagonally. A very frequently asked question is one about the 35 mm format focal length equivalent of the lenses used on The diagonal of which is 67.30mm making the standard lens as 65mm possibly 70mm. Re: ?medium format vs 35mm(lens equivalent)?? So now you could alter the 645 format to 35mm proportions which works out as 56mm x 37.33mm. mmCalc is a super simple photography focal length calculator. Ok, what is DOF for 80mm F2.8, 400mm F2.8, 135mm F4, 500mm F5.6? 6 x 6 is actually 56 x 56 from which the diagonal is 79.20mm. Making the 6 x 6 format the same proportions as 35mm format, Making the 35mm format the same proportions as the 645 format. the smaller frame. So it is up to you whichever format suits you best as to which are the correct equivalent focal lengths. Ok, then what is similar aperture value in 35mm? The equivalent 35 you might ask. It is OK for landscapes but portraits look odd, as the picture is too tall. This would be equivalent to 50mm on a 35mm or FF digital camera. On a Canon you multiply it by 1.6x to get 28.8-53.4 in its 35mm equivalent. How do the focal lengths of standard lenses for medium format cameras (75mm/80mm) compare with 40mm-58mm on 35mm cameras? 35mm equivalent focal length (mm): You can find information on the sensor size in your camera in the manual, product information of the manufacturer of on DPReview.com . I'm looking to expand my lens collection for it, but i'm not sure what I want to grab, since there are quite a few choices in focal length and I like to visually see the differences. not only from this nominal focal length, but also from that of other Zeiss/Hasselblad lenses having nominally not a problem, i.e. If you are shooting portraits with a MF, you don't really need the equivalent of a 90mm lens on the 35mm format. It is Not your lens. If you know that 50mm is “normal” and that, say, 90mm is a “portrait” field of view in the 35mm (Film/DSLR) world, then what you need to know is these focal lengths yield different fields of view in the medium format world. If I have missed anything, please contact me and let me know. 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. 6x9 . IF YOU DO IT THAT WAY ! The actual focal lengths differ, Lets say the base is f8 (for the 35mm camera) what would be a similar aperture for 6x6 and 8x10? Equivalent focal lengths with 35mm cameras. And of course, this is just 35 mm; with medium and large format you get even more detail, and the larger you keep going the possibilities keep skyrocketing. Horizontal Angle Of View. If you have the kit 18-55 on a nikon you multiply it by 1.5x which is 27-82.5mm in its 35mm equivalent. With medium format 6x6 film you get 56 x 56 = 3,136 sq mm, which is 282 megapixel. The calculator is compatible with all the standard film formats such as 6x4.5, 6x6 and 6x7 etc. It is also interesting to note that the 645 format is all but the same ! It is enhanced Yashica-D with the added ability to use 35mm film as an alternative to 120.To use 35mm requires an adaptor kit. If you have the kit 18-55 on a nikon you multiply it by 1.5x which is 27-82.5mm in its 35mm equivalent. (the square root of 24 squared + 36 squared). A 35mm lens on a 67 format camera is probably a little wider than a 19mm equivalent in a 35mm camera. Previous post: Tales of the unexpected with a Rolleiflex T, Next post: The Church and Abbey of St. Augustine, Copyright © Club Rollei User 2017 Privacy Policy, Tales of the unexpected with a Rolleiflex T. Making the 6 x 6 format the same proportions as 35mm format. As a result, the diagonal often has to be taken as the basis for comparisons. Method 4: divide the diagonal of the 120 frame by the diagonal of the 35mm frame, then divide the medium-format focal length by the resulting number. Ok, what is DOF for 80mm F2.8, 400mm F2.8, 135mm F4, 500mm F5.6? The aspect ratios of 6x6 format (1:1) and Method 4: divide the diagonal of the 120 frame by the diagonal of the 35mm frame, then divide the medium-format focal length by the resulting number. From that you can calculate other focal lengths. 10x12. The Mamiya 6 MF is an interchangeable lens medium format rangefinder, which will shoot 6×6 frames on both 120/220 roll film or, with the aid of optional masks, permits you to change to 6×4.5 medium format and panoramic format 35mm film. On a Canon you multiply it by 1.6x to get 28.8-53.4 in its 35mm equivalent. I found that I could produce a 12"x18" print (on 16"x20" paper) from 35mm (HP5+, Perceptol, 200ASA)with very careful technique which could compare well with a 16"x20" print from a 6x7 neg using the same film - and could be displayed together.
