35mm Minolta camera has shudder issues

It sounds like the film sensor has gone bad. You can check and see if any local repair shops still service these, as most don't due to lack of parts.

The Konica Minolta Maxxum 5xi QD is a 35mm film camera and does not use an SD card. If you want your photos taken on an SD card, you will need to get a digital SLR.

Hope that helps,

Cameras, especially film cameras, do not use "SIM" cards. There were some models of Minolta film cameras that used exposure cards for auto-settings but only cellular phones and devices with cellular interfaces (iPads) use SIM cards. Here's a copy of the Maxxum 5 manual if that helps.

Hi, On Minolta's ERR means that the film hasn't been loaded in the camera properly so you'll want to reload the film.

XG1:
Two 1.55v silver-oxide (SR44 or equivalent), or two 1.5v alkaline-manganese (LR44 or equivalent).

The film counter moves without the film inside the camera.
You will need to replace the film counter assembly.

Broken gears in Advance Assembly.
Needs service.

the shutter assembly is not fully open when shooting. Maybe the motor driving is possibly weak already. You have to bring it to the service center, if the price is not right, better buy a digital camera compatible with your minolta lenses. ( films are getting obsolete fast, but the lenses are not)

clean the contact terminals inside the film compartment. Your camera has an abnormal autorewind switch detection.
