am I stupid or is lens broken
Anonymous 01/09/25(Thu)19:22:49 | 45 comments | 1 images
I got myself a used DSLR with a few lenses a few days ago. It's a Canon EOS 700D. One of the lenses is the EF-S 24mm f/2.8 STM. The lens works fine in AF but when turned to MF it does nothing when turning the focus ring. Did I miss something or is the lens just broken?

??? So manual focus is broken but autofocus works?

ime, try to half hold the shutter button (once, as in lettin the cam measure light), then try to use the focus ring
t. i have an STM objective

As this Anon suggested, it's because manual focus override is done electronically. Try resetting your AF settings if it still doesn't work

its probably a setting on the camera, those things are focus by wire

Thank you all for your replies, Anons!

yes. autofocus works like a charm
>>4398308
also does not work unfortunately. Neither in AF nor in MF mode.
>>4398310
I tried playing around with different combinations of focus settings but still nothing.
>>4398374
Do you know what setting you influence that?

the only switch I see on the lens is the AF/MF-switch. Yes, I have tried that. The camera also recognizes that.

Been to a local camera shop today. The guy working there tried the lens on another camera. Same problems. The focus ring seems to be broken but repairing it would cost more than getting a new lens. Guess I'll have to live with just AF.
Thanks, guys

As you should. Your camera is designed for AF, not MF. If you have an AF lens, there's very little reason to use MF.

Autofocus never places DOF correctly. DOF is a field with a shape. Autofocus just tries to maximize the sharpness of whats under a little square at whatever minimum aperture the algorithm runs the lens at (f5.6 usually). Only a human eye can do whole-field focusing, and only with stop down preview.

do you have an example of what you mean by DoF placed correctly vs incorrectly?
do you know of any photographers i can look into using this method?

Pick up your camera and notice that if you focus on a corner your center can be out of focus, and there’s an in between where the center is not perfectly focused but looks good when not pixel peeping and the corners are ok.
That’s really all it is, plus autofocus not seeing the final shot if its not running at the shooting aperture. You can see the final shot if your camera has a DOF preview toggle.

that just sounds like a lens with bad field curvature
> where the center is not perfectly focused but looks good
this, what's an example of what this looks like?

By definition, DoF is a region around the point of focus in which things are acceptably sharp. This is of course subjective and contextual. Without DoF, only a plane would be in focus, not a region. If you want multiple items of different depth to be in acceptable focus, the optimal point of focus is going to be somewhere in-between them. Often times, AF isn't going to get you there because there's nothing to focus on at the arbitrary midpoint where you want the point of focus to be.

You're a fag. A ten-second google search will bring up scores of articles on the topic of uneven field curvature in optical lenses.

i just wanted to see an example of an image you don't think AF could get, that sounds interesting
it's new to me that field curvature means AF doesn't work anymore
it's a shame you don't take any photos yourself, but thanks for the info anyways

NTA. It IS a thing, but I've never personally experienced this except for my shitty decade-old MFTurd, and even then it isn't some starkly noticable feature of the photo, it's like, oh, if I focus on something at the edge of my shot with the middle AF point, then recompose it back to the edge, the field of focus isn't perfect at f/2.8.
It's really only a thing at the thinnest DoFs and with extreme focus repositioning.

Autofocus is often off ever so slightly, especially in bad light.

so to confirm, you think field curvature makes using autofocus not possible? again, that's news to me
seems like the real solution is to stop buying shitty lenses
i wasn't asking anyone to go do a stupid snapshot, they said it was a technique they used "often", so i think it's fair to ask for an example
i wanted to see an image you didn't think AF could get, since that was the claim
sorry that you think we shouldn't post photos on a photo board

Field curvature and hyperfocal shooting mean manual focus has a use and autofocus only is cucked. You do not need an example for this, nophoto. You need to grow a brain and learn to read.
