In Topic: Olympus omd m1 II focus issue

Also don't forget the crop factor also applies to Depth of field.  At f8, you get the same depth of field as you would with f16 on a full frame camera, with the same framing.  I mostly stick with f8 for my macro shots.

I'd email the shop. INON normally includes grease with strobes and even with their torches.


In Topic: Olympus 60mm and EM1Mk2 Strange Behavior

14 November 2018 - 04:26 AM

The hunting behavior sounds unusual to me.  I have the EM-1 MkII and use the 60mm macro with it.  Previously I used the 60mm with the EM-5MkII and the AF is much nicer with the EM-1 MkII.  Both cameras I used the full 0.19 - infinity range without much problem.  The EM-5 II would hunt and focus on particulates sometimes, but the EM-1 MkII much less so. 

 

What settings do you use for AF?  I use C-AF plus Tracking, with the AEL/AFL button assigned for rear button AF which is mode 3 in the menus so the shutter button only does AEL and IS start.  I also have mode3 for the AF scanner.   AF limiter is set to off on the A1 menu screen.  I also have face priority off and AF focus adj off.  I use a single AF point and have it set to the small AF points. 

 

I have also used a preset MF distance assigned to a function key.  When you press the Fn key it goes straight to that distance. this can be handy if going for example from macro distance to fish portrait distance, you must press it again to reactivate AF as it will stay on the preset distance until you do.

 

If you are getting a lot of trouble with hunting I would suggest you might have a lens or camera issue as I find mine behaves it self quite well, the only time I run into issues is with a lot of particles in the water.

 

For an example of what it can do, I was on a dive at dusk last week in Lembeh shooting Mandarin fish, I found I could AF on the fish without a focus light in very dim lighting:

Yes it's the A7-II and that definitely does not support zoom.  The A7-I it's hard to tell if it supports zoom, I found one on Ebay and it had a key drawing and labelled the knob you see as Manual focus, but the websites don't say anything specific.  The cases are also very buoyant so need some weight to make them usable.

There's another issue with the Meikon housing, from a website selling them

 

"Provides mechanical controls for all essential camera functions except the zoom"

 

Without a zoom gear the whole thing seems a bit pointless to me.  If you are after a compact backup consider something like Canon G7X MkII in a Fanatsea housing or one of the older Sony RX100 also in a Fantasea.
