But while both lenses are equally bright, the Full Frame lens projects a larger image circle to match the four times larger sensor. As a result, both lenses are similarly bright, but the Full Frame lens passed four times the light volume. Equivalent Aperture for Depth of Field Explained. Aperture influences depth of field. Lens focal length conversion table of 135 / 35mm small format cameras, medium formats, 6x6, 645, 6x7, and APS-C format. Lenses from 15mm to 135mm with angle of views, ultra-wide angle lenses to telephoto lenses. Focal length conversion for medium format image sensors of 44x33, 48x36mm. Converted values are matched with availability of lenses 1. My question is. Can we buy adapter to convert apsc sony lense to full frame lense ? 2. Which lense is better rokinon 12mm or 14mm lense ? In terms of professional astro shoot. 3. Is there a full frame lense with 12mm range and f2.0 or less ? In the same price range as rokinon lenses. Thanks for your time. Sent from my SM-G955U using Tapatalk For sensors similar to Super 35, APS-C has an aperture of 25.1×16.7mm. APS-C differentiates itself from Super 35 in its primary use in photography. You can still capture videos using APS-C settings, but it is not typically designated for filmmaking. APS-C is a versatile sensor used by professional and amateur photographers, with most lenses sarah_fox. Members. 6k. Posted March 1, 2013.

24-70mm on a 1.6 crop camera will give you the same field of view as 38-112 on a full frame camera.

24-70mm on a full frame camera will give you the same field of view as 15-44mm on a 1.6 crop frame camera, so 17-52 on the crop wouldn't be quite as wide as that.

. An illustration showing how the same lens will produce a wider angle of view on a full frame camera compared to an APS-C camera, and how a 70mm lens on a full frame is the 35mm equivalent to 50mm I have a 24-105mm f4 lens, if it is used on an aps-c body such as the A6400, what is the equivalent f stop, if shot wide open? f4 on a ff = ?? on an aps-c. Thank you Dave. The lens will act (for depth of of field and angle of view) like a 36-158mm f6 lens would on full frame. Originally posted by troglodyte. 0.65 * 36mm = 23.4mm. 0.65 * 24mm = 15.6mm. The Pentax APS-C sensor is 23.4mm x 15.6mm. Depends if it has a Sony or Samsung sensor. Samsung 23.4 x 15.6 mm. Sony 23.5 x 15.7 mm or slightly larger for the older ones. And not all film cameras had the same frame size either so I think a simple round figure is Crop Factor Calculator. Get the full-frame (35mm) equivalent focal length and aperture for different sensor sizes. Just enter the focal length and maximum aperture of your lens and then choose a sensor size. My mm f/ lens, on a sensor, is equivalent to a 157.5mm f/2.1 lens. The crop factor for that sensor is 1.5x. In fact APS-C sized sensors (found in cameras like the C300, 7D, etc.) are the closest digital equivalents to real 35mm motion picture film, so technically if you want to stay as true to 35mm cinematography as possible, you should be shooting on APS-C sensors (which have a crop factor of about 1.6 when compared to full frame). yVr1w.
