dfigueire: I am confused.
quote: Flexible AF-C section
"the a7R II seems to have a strange bug when used in any continuous focus mode: when holding down AF ON and switching between subjects that are more than several meters apart in depth, all of the lenses that I tested on the camera occasionally refused to refocus."

So he expects that once he has a subject lock-on that it can switch to another subject and follow it without letting go of AF button? So confused, doesn't that mean his DSLR has the bug. Please help me understand.

But that is my whole point. To acquire a different focus object I would let go of button, right. If I press the AF button for a subject and it jump to some other subject I didn't want it seems wrong. Guess I just don't understand. Thanks for reply.

erichK: For me, the obvious big change-in-direction for Panasonic here is that they have finally added in-body-image-stabiliztion. This finally makes it possible to fully use such little gems as the Olympus 12f2, and 17, 45 and 75 f1.8 lenses as well as the Oly 60 f2.3 1:1 macro with a Panasonic body which offers such features as the "silent mode". Better still, one that turns of other distractions like the focus-assist light and audible function signals at the same time.

I often shoot at classical music performances where even the very quiet shutter of the OM-D has to be timed carefully. so the comprehensively quiet would be wonderful. The spoiler is the fact that they did not include a mic input. We do also use a separate Sound Design digital recorder with a pair of good quality Schoepps mics, but in the past synchronizing separate audio with video has proved a real chore. It would be much simpler to simply be able to use the decent little Olympus hot-shoe mics, or use Rhode ones.

Yeap! The real stunner is the in-body IS. Wonder if its smart enough to turn itself off for lenses with OIS?

Tom Caldwell: Big red dedicated video buttons right under the thumb are a complete turn off for me and anyone else who doesn't do video. My NX10 is looking pretty good and now seems even better.

Really, you don't do video, so you think the button is a turn off. Cause you are the only person on the planet, and everyone thinks just like you. Is there something of real value that you don't like. Say....Image Quality. Maybe the texture isn't right. Sheesh!

Hi dw1338, the purpose of bracketing is not DOF. Its diffraction. Its finding the sweetspot of the lens/sensor combination to maximize sharpness. Take a look at the cambridgeincolor link below.

Hi Chick,

First of all even though I'm a Canon shooter. The D3 is awesome. But I would add a couple of tips. If you are a experienced photographer please forgive me. One thing to think about, since the focus is at a far distance, is you should consider bracketing the aperture. Because of diffraction ( http://www.cambridgeincolour.com/tutorials/diffraction-photography.htm , play with the calculator in the middle of the page.) I would consider f11 to f8. I think you would get even sharper results. Oh then on the other end of this issue is depth of field. So bracket the aperture. As far as the Gamma change, please remember photography is an art. Therefore, the way it is could very well be perfect. Since you did use NIK to get a more HDR look by reducing the Gamma we get it to pop a little better.

Once again, congrats on a well made photograph and I understand the effort to get such a shot. Oh and thanks for the permission. Hooray for the clouds which cooperated with you.

Hi Chick,

I think this is one of the most amazing pictures of Yosemite. I wanted to get you permission to use this as my computer background (I change it every week). Also would like to get your permission to print it. I live in the San Francisco bay area and you cannot image how many photographer try to get this shot. You have to wait for the right time and be in the right place. But you got it.

One more thing, if you bring the gamma down about 20-30% it rocks even more. Well in my opinion.
