Web Analytics RiceHigh's Pentax Blog: No Focus Point Indication in Finder for the K-x?

No Focus Point Indication in Finder for the K-x?

The K-x has a 11-point SAFOX VIII, but it has no focus point indication of any kind in the viewfinder, neither the overlaid red illumination on focusing screen nor any indication/information to be displayed in the status/info area at the bottom of the finder. Just read this latest hands-on report and follow on the discussions along the thread:-

http://www.pentaxforums.com/forums/pentax-news-rumors/73789-hands-pentax-event-last-night.html

The design is that the focus point must be selected with the display and indication on the back LCD but there still will be no indication of any kind on which focus point(s) that the camera selects nor the user can have any idea about it *during* shooting, when he/she has been looking at/through the finder.

Well, whilst I don't think this indication is very important for bodies like the *ist DL or the K-m, of which all focus points are more or less close to the centre of the frame (3 points and 5 points respectively), this time I think it is not much acceptable for a wide 11-point AF covered area to have no indication at all in the finder, which will surely create much inconvenience and problems.

In fact, DPR criticised much in their K-m review about the lack of focus point indication (which I didn't agree that it was a major problem, mainly because of that all the five points are close to the frame centre), but now the problem has been even made to be more serious by Pentax and could be a *real* issue this time. From the commercial point of view, why Pentax could not respect the DPR by considering their point of concern as raised and re-include the focus illumination, just like what is available in the K100D and the *ist D/DS? How much cost they can save in eliminating this facility? Not much, I'm afraid. But one thing is for sure, DPR will give adverse comment again in their upcoming K-x review, if any, possibly in an even more strong tone for the problem and more marks will be deducted in their review. So, why Pentax/Hoya didn't listen?

Even they didn't, won't and don't listen, I think they should think at least themselves if such a handicapped design is practically usable for the users, or not.

There are sound beep and focus confirmation indicator. LCD indicator. But no in VF.
It's rather silly.
RH agree 100% (for once :)

This is a VERY VERY serious oversight - absolutely inexcusable in fact.

Pentax have crippled this potentially fabulous camera, in fact no pro will EVER buy this camera as a backup body, and I can just hear salespeople trying to explain to potential Pentax customers how to determine focus when they have just tried another brand. Gosh even the CHEAPEST crappiest P&S tells you what it's focussing on!!!

This and the (far less serious) decision to restrict those wonderful colour combinations to Japan only, really makes me scratch my head. Why do you think that the iPod Nano holds the record for the fastest selling electronic device in history - 100 MILLION sold in 3 years? Out of the 220 million total iPods sold since 2001. It is universally acknowledged that the beautiful colours (obviously in addition to the other wonderful design and features) have had a major and direct impact on these sales.

Pentax - Ned - are you listening to the REAL WORLD ??? Do you WANT to be a minow for years to come? Do you think Coca Cola and McDonalds got to global supremacy through product quality? NO it is clever, consistent and MASSIVE marketing.

We, the photographers of all walks of life are screaming in the many thousands of forum posts because WE CARE AND WANT TO LOVE PENTAX and BUY Pentax!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Well put, chillgreg.
To say honest K-x will be one of the best-sellers in Japan, but it's really POPS.

This is the only major downer in an otherwise fantastic camera. The K-x won't get a superimposed AF point display without a hardware change (maybe in its successor), but there's another solution which can allow Pentax to solve it satisfactorily in firmware:

Will they do it? Now that's an entirely different issue...

True, better than nothing, one can probably get used to it. I prefer regular indicators though.

There is another major downer though. AA batteries. Pentax, stop it. Please. I've just played with the K20D, and its AF seems to be at least twice as fast as the one on my *istDs. Then I plugged in the power supply of my Pentax, and guess what: The AF was almost as fast as the one on the K20D (though not as precise perhaps). I had rechargeable NiMHs in my camera.
Your power supply was at 7.4V? :-)

Btw, I think you may be interested in my this previous measurebation test and the relationship of different voltage and AF speed + system time lag for the K-m are tested:-

Naw, the power supply outputs 6.5V, it's the D-AC10 from Pentax, which is designed for my *istDs. I have to measure, but it feels much faster with the AC adapter.
I had a look at the proposed solution. Better than nothing. Pentax might be too embarrassed to release such a rudimentary fix.

Why not use the LCD? Include an option that shows a nice graphic diagram of the focussing screen for a few seconds when the shutter is half-pressed? I'm not talking about Live-View, just an attractive representation.

Thoughts?
In what situation would you want focus indicators?? They only tell which point is being used to focus, not even that it is in focus yet.

I can think of a couple situations, but when really thinkign about them, I wouldn't care for them:

If the subject is moving or hard to track like a jet or RF plane and there is nothing that can come in the foreground, then you can use full AF because it can go from one AF point to the other and its pretty unlikely you will miss focus, unless there are multiple planes, but all the indicator will do is tell you which one is in focus. If it tells you the wrong one is, you can wait then snap a picture. Without the indicator, you just take the picture and maybe it turns out better than you wanted.

If there are things coming in-front of the object you are trying to focus on that is moving (sports with lots of people) then you would never want to use full AF because it will focus on other people, and you want to specify the exact point (or maybe a set of points), otherwise it will focus on completely random people that I dont want to focus on. if you did you'd have half the shots missfocused (although it would tell you where it missfocused) where selecting the focus point would give you 100% and you wouldn't need indicators.

However it is a feature that when I first got into DSLRs I thought was cool and expected every camera to have it. In that sense, I guarantee it will turn off buyers, for a very small practical reason.

Some people prefer to choose the focus point on a particular object while framing, regardless of the object being stationary or moving. Without an indication inside the viewfinder, that desired operation is not possible.
A lot of Pentax SLR cameras has no AF indicators in VF. It's not very comfort, but it's not big problem.
The user can choose AF points at LCD and use LV. It's camera for beginners from P&S.
Of the DSLR's I have tried with AF-point indicators, it was not really possible to change the focus point with my face up against the camera and looking through the viewfinder. Which model can you do this with?
If you are referring to lining up the exact point in the viewfinder with the exact point on the object, even with a simplistic overlay, you can tell exactly what area the AF-point is in if you have a memory of more than 1 second.
BTW, the af-point sections are not nearly as small as the LED and are misleading you if you think that that specific spot that lights up will be exactly what it focuses on.
I am using the Pentax *istDs. The control cross thing is always under my right thumb, with it I very often change the focus point while looking through the viewfinder. Pressing the OK button in the center then activates the AF. Not being able to do this would be a deal breaker for me. Admittedly though the K-m/K-x would be a step down from my *istDs, people who buy their first DSLR might not miss this feature as much as I do.
