Focal length? I have a small place with about a 4 meter length. I wanna shoot full body pictures standing. I have a canon eos 2000d with a 55mm zoom lens. Can i zoom out to 18mm and shoot? Or will my pictures get distorted? submitted by /u/mich706e

What focal length should I look at for portraits on APSC? So I have tried to do some research on my own. From what I gather the wider you go in focal length and especially wide angle lenses can add distortion to people that aren’t necessarily faltering. I think similarly going longer in focal length adds its own distortion if I’m remembering correctly. Up to a certain focal length these distortions can…

Is the focal length stated on Canon EF-S lenses the actual the focal length adjusting for the crop factor, or is it just using the same focal length factor from EF lenses? Sorry for the (somewhat) janky English, but; I was wondering if the focal length written on EF-S lenses the actual focal length that it can shoot from (for example: 18mm from an 18-55mm kit lens actually being 18mm) and it not being cropped due to the APS-C sensor crop factor. Because if you need a wider FOV, do you actually need to get a very w…

Focal length and image sizes not matching up?? Someone tell me where I’m going wrong. So I just recently got a new lens hoping it would give me a big zoom, but for some reason, my calculations are not matching up… I wanna know where I went wrong. I have a 55-250 EF-S lens and I got a new 75-300 mm EF lens. Now because my camera is a canon crop sensor camera, I was hoping to get an effective focal length of 480mm ie 300*1.6. I w…

Focal length and dof? I’ve heard everyone say the longer the focal length, the smaller the dof, but does this statement take focal distance into account? I can totally understand it if the focal distance is the same, since with a wide angle lens, anything more than a kilometer away is basically on the same plane to the lens(sense of depth gets lost at far away), so f…

What does ‘equivalent focal length’ mean? Hello, I’m a beginner and got this Lumix 25mm Prime Lens from my dad. He said something that even though it was a 25mm it was equivalent to a 50mm? I’m so lost, what does that even mean? That it shoots like a 50mm lens or? I’m using the lens on Olympus E-M10 Mark 3 if that matters. Thanks beforehand! submitted by /u/fashionicon_haha

What focal length do I need to shoot a distant subject? I’m planning a photography project, and one of the sites I want to photography is about 3.5-5.5 nautical miles away from the vantage points I have listed. I’m wondering what focal length I need to make a good composition. I have an 80-200mm lens, a 75-300mm lens (which needs repair, and isn’t my go to lens but it has that extra reach), and I’m p…

Gaps in focal length across 3 lenses and minimum aperture? I currently have a Sigma 24-70 2.8 that isn’t quite as sharp as I would like it to be. I have a 50 1.8 and a 70-200 2.8 as well. I’m considering getting a 17-40 f4 to replace the 24-70. Am I likely to miss the 40-49 and 51-69 gaps in focal length? Also, how much will I hate a minimum aperture of f4 after shooting with faster glass for years? I’m…

iPhone .5 lens equivalent/focal length? Hello, I am looking for a lens focal length/type that will serve as an equivalent to the iPhone .5 lens, I enjoy the distortion when taking pictures up close of things that are round to make them more exaggerated but not so much as a fisheye.

Any ways to get a better shot without high focal length lens? Saw this eagle and decided to take some shots. Unfortunately I couldn’t really get good pictures out of it. I’m using a 23mm lens on a Sony 6400 camera. The end product is a heavily cropped photo which is… Kind of bad quality. Just wondering if there’s any way to get good picture without having to zoom in. Like for me in this case chanced u…
