Re: manual focus peaking/magnify

I use AF-M on my E-M1 and FP comes in handy for difficult subjects and macro I find.

It's difficult to be specific, but I find it very useful on occasions....FP that is.

Re: manual focus peaking/magnify

I too use it for macro work, and also for long MF lenses.

When looking at an edge of a subject, such as fence posts/railings, the peaking can be seen as a band moving towards and away from you. I've yet to determine if the band is similar to the DoF, so I will play with that and see if it is indeed yet more of this very good feature.

Re: manual focus peaking/magnify

One thing to be aware of - when the E-M1 was new I found out the hard way that if you set the viewfinder refresh rate to Fast, it disabled all the focus peaking options. It may be that with later firmware upgrades this restriction has been removed, or that there is less need to set the fast refresh rate - at first I found the viewfinder really jerky, but it improved slightly with fast refresh.

I could understand that having fast refresh and peaking active at the same time would put a heavy load on the processor, and if you are in conditions where peaking is useful you probably don't need the fast refresh. But I thought it was a bit off to just disable the option - far better to reset to standard refresh when peaking is enabled. It may be that this has been done in firmware now - I just got used to not having it, so I haven't looked for it.

Re: manual focus peaking/magnify

I've just tried it out - it is different from how I remembered it which means that it may have changed, or (more likely) my internal memory has been corrupted

With the latest firmware (3.1) if you set the Frame Rate to High (Menu -> Cogs -> D, second page) it looks as if it does not disable focus peaking. However, if you set peaking on (Menu -> Cogs -> A -> MF Assist) it automagically sets the refresh rate to Normal.

I think, but am not sure, that if you assign peaking to a button to make it easy to switch on and off, it will reset the frame rate to normal even when peaking is not active. If you don't set frame rate to high then clearly this is all irrelevant - and I think the frame rate has been improved a lot since the original firmware so fast refresh is less important now.

Re: manual focus peaking/magnify

None of my camera support it so I don't use it all. There have certainly been times when it would have been useful...

I won't touch Firmware 3.1 with a barge pole, until absolutely essential, I'm still on 3.0.

Re: manual focus peaking/magnify

I use MF a lot as for almost all my macro work and rarely use it though I find is useful with the 12-40 etc.

I do not like focus magnifying in MF especially for macro it interferes with compostion/focus which can require split second timing to get the shot.

Re: manual focus peaking/magnify

Thanks for the thoughts; interesting

I'm not a fan of focus magnifying; might be more handy with a tripod/close up

I find setting the single focus point (all I use) manually works for me when I want or need more than 1/2 click and hold.

The only reason I was looking at FP was for doing some stacking photos

Re: manual focus peaking/magnify

For macro, and also I've found it very useful for wildlife with the 40-150/1.4 when the subject is partially behind grasses and twigs. For the latter, using it with magnification takes some practice, but I now prefer this.

Re: manual focus peaking/magnify

I like the Focus Peaking feature (E-M10 user), very useful though I would agree the magnification box can affect composition.

Focus Peaking on the GX7 is very well implemented, arguably more so than on the Olympus bodies and you can also move the magnification box around the screen...very useful.

Re: manual focus peaking/magnify

I use a lot of manual lenses, legacy and bought recently, including Samyang and Voigtlander lenses. On all I use magnify to focus on the subject, the longer the lens the less magnification I use. Then a tap on the central button on the control dial reverts to normal view for composition. Peaking doesn't seem to work on lenses with no electrical connection so I don't enable it.

Re: manual focus peaking/magnify

Cheers folks. I went chasing reflections [] yesterday and used focus peaking with the idea of stacking a few files together. Interesting concept for seeing what is and what is not in focus although it would be more handy when using a longer than my 20mm Pana lens.

Have to admit I was finding one fixed focal length lens a bit harder to come to grips with out in the paddock and near/over water. The 24-600 mm on the Lumix fz200 has spoilt me somewhat

Re: manual focus peaking/magnify

I'm not sure how accurate FP is in demonstrating depth of field - I seem to get inconsistent results (but I haven't really investigated and I just don't rely on it).

It is only adding a little more over 3.0 & Live View Boost 2 might come in handy for a particular night shoot perhaps, but the rest is for underwater use really.
