Hey all, I was lucky enough to buy Sigma for $100 – Bit something seems to be missing. You can tell by the lack of screws Evereything else seems to work, but the aperture csnnot be changed, it just says F — and rhere is a big vignenette circle. Any ideas if this is is fixable, and how so? TIA! submitted by /u/lewisstrang1

do long lenses like 300mm at “tight aperture” like f 6.3 still have enough bokeh? my lenses are 35/50/85mm 1.8 primes. and i love shooting at like 2.8 for lots of bokeh. i want to get a 70-300mm f4.3-f6.3 lens, when i look at f6.3 automatically i think it’s bad and won’t have the bokeh depth of field i want. but if i am shooting birds and the background will usually be really far away because it’s all outdoors, would there st…

Can someone help me understand why my aperture photos look like this? (w/ photos) Hi everyone, I’m brand new to photography but been watching lots of videos on YouTube. Took my camera out for a walk yesterday and took some nice (for me) photos using either full auto or full manual modes. Today was reading up on aperture priority and shutter priority settings and when to use them. However, I’ve found that going into the apertu…

constant aperture question (camera vs. lens)? Hi, Friends – I’m using my friend’s canon 15-35mm f/2.8 lens on a canon r6mii camera this weekend. As a novice, I’m confused as to why the lens is a constant 2.8, but on the camera itself I can stop down? Isn’t the whole point that I maintain the 2.8 through the entire focal range? submitted by /u/thatalsaceguy

Bought this Schneider Componar 50/3.5 because the seller stated it was manual focus. Does anyone know how to focus it tho? I can only change the aperture by rotating the outside so Im really confused rn https://preview.redd.it/gg589n7focge1.png?width=500&format=png&auto=webp&s=8a233215f2d936a39dc5e00e26e6df31f70cd72a submitted by /u/fiesinator

Is aperture equivalency a thing? Hey, I’ve always thought that there was some kind of equivalency between sensor sizes like focal length do. But these last few days, watching some photography content, I heard people saying omitting the equivalency for aperture (for exemple for a Ricoh GRIII “28mm eq, f2.8”) or someone talking about how great his compact camera was for low light…

What are these white dots on the rear surface of my lens? I noticed after getting it back from an aperture mech repair. They don’t come off with 91% isopropyl. submitted by /u/famicomical

Why can’t my lens take sharp photos at maximum aperture? I own a Tamron 28-300mm 3.5/6.3 A06, the version without the image stabilizer. When I shoot with the widest aperture, the photos often come out with very blurry, soft edge, not sharp. This is different from when I stop down the aperture; in that case, the photos turn out much sharper, although obviously at the expense of depth of field and the a…

How can I efficiently learn how to use aperture and shutter speed adjustments on this camera? Hi everyone! I inherited this from my grandmother who loved photography, and I want to be able to master it. I first thought about taking my digital camera as a guide to set shutter speed and aperture, but I’m not sure if that’s the best way to learn using this camera and the best is just go with trial and error. The films are expensive and I j…

I’m an amateur with a sony a6100 and sigma 16mm f/1.4 shooting mostly pictures of my kid and wondering how to choose aperture? I saw a recommendation that you shouldn’t always shoot wide open. as an amateur i’ve fallen into the trap that bokeh looks amazing and is the most important especially when taking cute pictures of my kid. I usually shoot at 1.4 because i take pictures inside and want to maximize shutter speed and minimize iso. Is there any reason to be shooting …

How to take High aperture low light photos? How does this guy get these pictures at low light with such a high aperture? It could be because my camera is 20 years old but my f/5.6 can’t handle the darkness of a street lamp at sunset. https://www.instagram.com/share/BAIPuETXpG submitted by /u/SushuniTaco

Laowa 65mm 2.8 aperture ring misalignment? This is a brand new Laowa lens that I had a warranty repair on, for a crunchy focus ring upon receiving it. It was at a repair centre for 7 weeks. Got it back and the aperture ring is now misaligned. The first image is f16, the second f8. What would you guys do in this situation? submitted by /u/Sodiumflare

Looking for a lens with manual aperture adjustment. What would that be called? I’ve been using a analog camera for a bit, and found it easier to use the aperture through a sliding ring, instead of going through menus on my digital one. Is there a specific term for that? I’ve looked at fixed focal length, but they seem like they have a set aperture. Is there a mechanical reason this wouldn’t be possible? I have a nikon d340…

Unfocused images – Is it my aperture or am I not steady handed? Hi everyone, I’ve just started shooting analoge film (on a Pentax K1000) and am still trying to understand aperture settings. I understand the theory of aperture mostly…however most of the shots on my recent roll came out looking really unfocused. I was shooting on Kodak Gold 400 and mostly I kept to an aperture of 16-22 (changing shutter spe…

D750 and AFS 200-500mm 5.6. Aperture not moving? I bought a used Nikon AFS 200 to 500 mm 5.6 lens for my Nikon d750. It looks an immaculate condition, it even included the original box and paperwork. The previous owners say stated that they used it very rarely. It shoots great at 5.6. but any attempt to move the aperture causes the camera to display error on the LCD after snapping the picture…
