Macro mess
Sep 21, 2020 15:05:02 #
Took some shots this morning with extenders. Could not get the auto focus to stay still. This is the result. Any suggestions or tips?

My understanding is that you get about a millimeter or less of depth of focus when doing macro. Many people prefer to use a tripod for this reason, and some use manual focus.
Beyond that, however, you need a lot more light on this subject. The photo demonstrates a lot of noise issues.

Although under some circumstances I have gotten good results with AF, most macro is done manual focus or with electronic control (tethering or programed focus control of some type).
As said it needed more light, esp with using AF. The subject is all shades of the same color and gives little contrast for AF to detect.

Interesting image as is Mike. I like it!

I almost always turn the AF off and stick the camera on a tripod. I then focus via moving the camera back and forth to the subject. In the old film days everyone made a "camera rail" to move the camera and lens back and forth to focus. I see on eBay the go from $3 and up.

Thanks to all of you who have replied. I was using my Zeiss Batis f/1.8, 85 mm lens. That lens does not allow manual focus, so I am going to have to work with another lens or learn a different approach.

I'll bet the camera has AF on/off. Same thing only different

The camera is on Manual.

Camera on manual does not necessarily mean that the AF is off. Usually there is a switch on the camera body or you have to go into the menu to switch the AF on or off depending on the camera ....what camera are you using?

I would think your camera is capable of aperture oriented photo. If so switch to that and use a tripod for the slow shutter speed. Old lenses used to have depth of field on the lens is not there are charts on the internet.

My old Nikon has that switch, but my Sony a7R3 does not.

I have the Sony a7Riv, the AF, on/off mode is in the Menu AF1 page 5 First item "Focus Mode" push the center button on the circular ring to get to AF-S, AF-C, etc and scroll until you get to MF. center button MF Thats will put you in full Manual Focus . somewhere in your view finder you will also see MF. Now you can focus manually and you can focus via Focus Peaking, in your choice of colors. PS, don't forget to go back and turn it off after you're done macro work. Otherwise it will be off the next time you use your camera.

Outstanding! I appreciate your work. My Sony lenses have the lens switch, so I never investigated the camera body. Thanks again!
