Small single target AF point

One of the main criticisms that us birders (and others) had of the E-M5 was that the AF single target point was too large for subjects such as a small bird in a large bush. The E-M1 now has an additional Small single target point available for AF. Initially I wasn't sure whether this was still small enough compared to the E5 but some recent practice has given me much confidence that this addition is certainly up to the job.

This Blue tit, although only partly hidden by twigs but very close to larger objects at a closer distance would have been a bit hit and miss for the E-M5, but is plain sailing for the E-M1:



This female Reed Bunting, being almost entirely hidden by vegetation at various distances would have been a no-go area for the E-M5 but a breeze for the E-M1. This one of six images, all taken and focused separately that are in focus:



Hoorah! A major leap in AF performance IMO.

David

Interesting!

Does the E5 have a spot as small as the E-M1 then?

I like the reed bunting one!

Re: Small single target AF point

I thought I saw a thread a while ago which talked about this on EM-1 and someone said the EM-5 did have one - or is that wishful thinking for me?

I seem to be be getting more consistent results with the E-M1 than the E5 but that may be because I have improved on my weaknesses.

Never found a "Small" single target facility on the E-M5 in the 15 months I've had it.

Re: Small single target AF point

Good results, David. I think you could select a small box on the M5, but if I recall there was some discussion on its effectiveness, or lack of.

Re: Small single target AF point

Hi I have the EM 5 and it does have small focus point and it works quite well better then my E30.
Here is a female Ruff in the reeds this is about a quarter of the image.

As you can see it is in focus.

Oh and the bird was walking through so not static.

Dave

Super shot Dave, nicely done. The expandable single target point on the M1 appears the same size as the expandable single target point on the M5 but the M1 has the additional "Small" single target point which appears in the EVF to be roughly half the area of the standard single point. Whatever the apparent dimensions the M1 in my experience certainly performs way better than the M5 for these difficult small subjects.

How do you select the smaller focus point Dave? Sorry for being dopey today.

Re: Small single target AF point

Hi I have it set to the function button on the battery grip, if I remember you select focus point then reduce to the single AF point, Then press info button then use the front wheel then rotate until it goes to x14 then it should be at it's smallest which is quite alot smaller than the single AF point.

you can then asign this to a function button, then when you press the function button it will auto reduce to a very small AF.

Dave

Re: Small single target AF point

According to the M5 manual the single target AF point is adjustable using Zoom AF down to 14x in the same way as the M1, the wording is identical in each manual. However the M1 has the availability of an additional smaller, non adjustable single point - there is no mention of this in the M5 manual nor have I been able to find it on my example.

Re: Small single target AF point

I agree with the value of the small single spot, Plus having the magnify function set to a button (I use the DOF button on the front of the body as it falls naturally under my finger when I need it)

With the EM-5 I have the small box setting sorted but never found how to keep it in place as soon as I half-pressed the shutter button, which was a bit of a pain. With the EM-1 this appears to be the normal setting which makes magnify single spot focus then recompose an absolute doddle, focusing on the eye then moving very slightly to the composition I want (takes a bit of thought though, so I'm mainly working with 5X mag for this style of shot)

Re: Small single target AF point

Hi Brian I have it set on the battery grip function2 and it stays set to x14 all the time.
Or until I switch off or if I go into the main menu which is not very often the I just press the function button again, and move it around the screen or EVF with the arrow keys this is the slow bit as it moves a pixel at a time in the direction of the arrow keys.

Dave

With the E-M5 you have to set the centre focus box to be the "Home" position to stop it wandering around. Menu "Cogs A" Set Home.

Re: Small single target AF point

Super pictures David showing some excellent focus control.

On the E-M5, once you have the small focus box up, press and hold the OK button and it will jump back to the centre. It seems to move around to be at the centre of the last thing you focussed on even if that was using the full 35 point focussing area and face detection to pick up someone in the corner of the frame.
