40-150 2.8 on EM1- Mk2 Stuck on Manual Focus (MF)

Jun 2, 2018

I haven't used the 40-150 in a little while, and the EM1 works fine, focusing AF, with other lenses.

But when I put on the 40-150, it doesn't autofocus and the front panel keeps showing MF.

What could be causing this?

Well if it is the focus ring clutch being engaged you are going to feel a bit dumb :).

Yes, it was.

I'm an idiot. I hadn't used it in a while, and was used to seeing an AF/MF switch on a Panasonic. Once I moved the clutch, yes it worked.

Thanks!

Not an idiot. I do it all the time during weddings. The ring gets moved and in the heat of the moment I forget why it won't focus. Since I only use back button focus I never need an mf switch. On all my canon and Panasonic lenses the switch is taped down on AF. You can't do that with the 40-150. It the only thing that keeps it from being perfect.

I made that mistake fairly frequently; I posted a thread here. Now I have disabled it in the menu.

The Fujifilm X-T5 is the company's latest classically-styled APS-C mirrorless camera. It gains the 40MP sensor and AF system from the X-H2 but in a body with a more stills-focused slant. We've been putting it through its paces.

DxO PureRAW 3 review: Give Adobe's apps a much-needed boost with modern AI algorithms

Adobe Photoshop and Lightroom impress in a lot of ways, but their noise reduction lags the competition and their lens corrections lack a real-world basis. DxO PureRAW 3 aims to come to their rescue without totally reinventing your workflow!

The Sony ZV-E1 is the company's latest vlogging-focused camera: a full-frame mirrorless camera based the FX3/a7S III sensor, aimed at YouTubers and 'creators' looking to go pro.

The Sony ZV-E1 is a full frame camera targeting YouTubers. Chris and Jordan are Youtubers, what do they think?
