Can the focus point on the OMD made be smaller?
Can the focus point on the OMD made be smaller?
There is a discussion at dpreview: Re: E-M5: How to adjust the focus area SIZE?: Micro Four Thirds Talk Forum: Digital Photography Review
Page 45 of the manual explains how to zoom, but doesn't answer the question.
Uwe, reading that page in the manual and looking at the graphs suggests strongly that the green rectangle covers the same area in the finder when you zoom, but this means that (because you are magnifying the image) the focus rectangle is commensurately smaller.
See "Comparison of AF and zoom frames" graphic, middle R of page. HTH, kl
Thanks, will check it out. Seems a bit weird to me.
I might not have been clear: the area of the green rectangle seems not to be able to be changed in the 100% image view—but if you follow the instructions on p. 45, you see that the rectangle area does not change as you zoom in to the image—but, in reality, because the part of the image you are viewing is being magnified, so too is the rectangle getting effectively smaller, covering smaller and smaller area of the original image. And, as far as I can see, as this magnified view is zoomed in the EVF, we are shown precisely the area of the 100% image that is being used to assess focus.
Had the OP on DPR followed these instructions, for example, at some magnification only the woman's head would have been covered by the rectangle, so the buildings behind would not have been a problem. At least, from reading that part of the manual, I believe this is how it works!
The following description was provided by Olympus for the EP3, I believe is applicable to the OMD as well:
"The AF frame has fixed dimensions; however, the size of the zoom frame can be reduced by adjusting the magnification factor of the zoom frame AF function. As the magnification is increased, the size of the zoom frame decreases. Because the camera only considers the picture information within the zoom frame when it sets autofocus, the result is that the camera uses a smaller area of the scene to determine focus. This configuration makes the camera achieve autofocus with greater precision than when sampling using the AF frame."
(source: E-P3 > Frequently Asked Questions)
The bad part is (atleast I have not been able to figure it out), the changes will NOT stick.
With this camera, ALL I want is being able to set it in Center-Point AF, and make the focus area very small.... AND, have this setting stick, so that I don't have to re-set it every time I turn the camera on. ;-(
Sam, if it's any consolation, I have not found a way to do that either.
There is a thread over at DPR where tips are being shared:
Tips and tricks for setting up the OM-D E-M5: Micro Four Thirds Talk Forum: Digital Photography Review
and (to Uwe) I was wrong; you can adjust the size of the rectangle. If you have not worked out how to do this, and assuming you have the SDP (or whatever the quick menu is called) showing, you press the button on the side of the EVF, and this brings up Live View on the LCD. Touching the lower LHS cycles you through a number of options; one of them is the focus point (pointing finger and rectangle).
As soon as that's operative, a sliding bar appears on the RHS of the LCD; moving that changes the magnification and the size of the rectangle.
Nowhere in the manual does this appear, as far as I have found!
Unfortunately I also could not find a way to make the smaller AF point stick. I also want a configuration where I can have the smaller AF point just in the center of the frame.
Hope Olympus can fix that in a FW release
Life is an ever changing journey
The Leica x1 has a very nice spot focus mode. Would be great if Oly could integrate something via firmware.
Besides that I now sometimes use face detection with the option to focus on the eyes. Seems to work (not allways) but I dont like to rely on such auto auto features.
This drove me nuts ;-(
Throughout the years, I've always set my focus in Center (as small as possible) and recompose after the AF is achieved (if needed). I guess I picked up this habit due to inadequate AF performance in earlier generations of Pentax DSLRs. With every digital/film camera I've ever used, this is a simple setup... and seems to me a gold standard feature. I guess not with the Olympus E-M5.
I had a heck of time trying to find a work around for this simple task with the E-M5.
I returned the camera !! ;-(
In a way, the E-M5 was the best digital camera I had ever owned/used. I may still lose the battle (with myself) and re-purchase the camera ;-)
Does Olympus have any place to report bugs? Seems to me this is a bug (camera doesn't remember the size of the focus box). If enough different people report this as a bug, maybe it would be fixed.
I'm really tempted to buy an EM-5, but this drives me nuts on my EPL-1 (which has other UI issues that I expect are actually fixed on the EM-5, but the focus box size is my biggest complaint) to the point where I'm not sure I can handle another Olympus camera unless they fix this.
I'm sure Olympus sees it as a feature, but if enough people consider it a bug and tell Olympus, maybe they could change their mind!
I really would to get an EM-5, but I'm not sure I could live with this bug.
Now how does the focus spot work on a NEX-7...
Even if we can't shrink it or make it stick... the question to me is: so is it not focusing correctly? I've only had mine for a day, but it's been pretty spot on for me. I, too, set the AF to focus in center spot, and I have not run into a case where I wished that it would focus on something else in the current box. If it missed, it's usually because I didn't put the box on the right subject :P And, if we make the box even smaller... then there's more chance for me to miss the subject.
There is a form to fill in. When I asked a technical question through this means, about low-pass filters, I received a response from a technical specialist who gave me very good information and advice.

@ Hosermage: you can shrink it (see my post above) but you need to do it each time you turn the camera on. Assuming yours wakes from sleep, the setting will be kept; if you turn off, it resets itself to default focus rectangle size. Not a problem for me.
What is a problem is that after five minutes or so, mine powers down and will not wake up. I must have a look though the menus and see what's not set correctly.
Is it in the "D" menu: "Auto Power Off: 5min"?
Yes by default it appears normal size after you switch off then on again, but the setting is remembered if you have Fn2 set to Magnify (press Fn2 and at the same time turn the front control dial through the options to get to Magnify). So all you need to do after switching on is hit Fn2 once and the small focus rectangle (or large if you like) will appear and stick while you are using the camera. Press Fn2 again and the focus point will fill the screen as per checking manual focus etc, press Fn2 again and you are back to your small focus rectangle.

Not sure what you guys talking about sticking. I set my focus area at the center spot and it stays.
Go to Gear , select AF/MF and scroll all the way to next page HOME SET. Here you have 3 options and select the center focus area.
Now this is like the E5, when you touch any of the 4 buttons with the arrows it shifts the focus point for you. I find this handy. If you dislike this feature, then you have the option to convert these 4 arrowed buttons to FUNCTION BUTTONS.
Sorry if I have barked up the wrong tree.
I think its just an oversight of not making the size change sticky. The Fuji X100 was the same way for a while.
There is no reason why they'd give you the option of changing the AF point size when using the touch to select focus point, which then continues to keep the smaller size for as long as you keep the camera on, or don't press the AF home button.
Its got to be just an oversight where its not remembered after power off and hopefully they will fix it.
Surprisingly though, I have yet to really find an issue of where the standard size AF box has given me any issue with focusing on the wrong thing
@ David: you'd think so, but not. On the way back from LA, I experimented with a number of combinations, and I had to remove the battery to get the thing to power on again (not even the power switch would wake it up!!!).
Definitely a bug.
@kit: Hm... mine will turn off after 5 minute, as it was set. And I just need to switch off/on to turn it back on. I'm running a test now to try "Auto Power Off: Off" to see if it turn off again. So far, sleep after 1 minute is activated, will update back soon.
David: definitely please keep us informed; it's the only irritation presently (I missed a shot out of the plane while I was trying different settings; I had to take the grip off and pull the battery to get it going again!).
OK, after 10 minutes, it wakes with a touch of the shutter button (half press).
I think it's working as expected! Now I wonder how much battery it eats while "sleeping"? I'm tempted to just leave it sleeping and manually turn off when I want.
Just checked my firmware, it's 1.1 and it was shipped to me from Spain, not sure if that matters, and it's chrome.
I did have a different problem today with the PL25. After playing around a bit, it started to have that famous rattlesnake sound, even though I had it on Aperture priority mode! The aperture started to jump around based on the light source it was pointed to. I simply had to turn off/on and it'll behave normal again. Seems like there's some software booboo there. They should have sent a prototype to Jono for testing!
If I switch to smaller focus point the histogram shuts off?
