The latest rumor for the FZ1000 show support for DFD. That would suggest that Panasonic is not keeping it just for the GH4 so we should see this in other m43 body updates over the next year.

With a 25-400mm equivalent f/2.8-4.0 lens that is going to be a very big camera, bigger even than the RX10. Based on the size and price of the RX10 the FZ1000 may weigh more than 1kg and cost over $1000.

I suppose that DFD is much easier to implement on a fixed lens camera than on an ILC provided you have enough processing power to run it.

Not necessarily. One reason the Sony is so large is the constant 2.8 lens. By dropping the max aperture to f4 by the time you reach 400mm equivalent, it may become a smaller lens overall vs the 200 mm f2.8 in the Sony. But you are correct, we cannot really tell until we see more.

That is the implication according the IR interview. DFD depends on lens profile data, so theoretically that could be mapped and baked into the firmware for the lens on the camera. Perhaps a little less cumbersome than having the DFD bokeh data loaded in the firmware for each lens...again, just speculating...

I am pretty shure it will drop to f4 a lot before 400mm equivalent. My uneducated guess is at around at least 100mm equivalent. Same as with lenses of the likes of rx100 1-2, Canon G1xII ore the Panasonic 14-140

do you know that? We do not know how well the 1"Panny sensor will score. We do not know how well it focusses. We do not know how big it is going to be. We do not know what price it is going to be. We do not know if it is weatherseald or not (might not be important oor you) we do not know how the lens will perform.

To my mind a lot of uncertainties.



However: on paper okey.



And as an aside: may be we need this cam for shooting BIF and wildlife as this lens has the reach may be also thequality m43 lenses of panasonic lakc beyond 100 mm 9200mm equiv)...



Very nice move for those whow ant such a superzoom. But hownice is this for those who want a 100-250 f2.8 to f4, nowing Panny is not going to provide this?? I would say that those who an ILC are probably uour more loyal clients. But not gettin a telezoom of good FL and IQ AND AF is not showing they feel that way.

What is DFD?

This is from DPR's quick summary of the GH4 camera:
Sergey_Green said:
Probably the biggest change is a feature called DFD (Depth-From-Defocus) autofocus, where the camera uses image blur to judge subject distance. During live view (before a half-press of the shutter button), the camera will occasionally make a tiny adjustment to focus, to check whether subjects in the frame are in front of or behind the current focus point. In addition to this information, the camera judges how far out-of-focus objects in the scene are, based on how blurred they are, assessed using a profile detailing the blur behavior of the lens at its current aperture. Although this combination of data itself doesn't give the GH4 enough information to achieve precise focus, it does give it a clear idea of where it should start using conventional contrast detection AF process to achieve fine focus.

For now the camera will only have profiles for the company's 22 Micro Four Thirds lenses - meaning any DFD speed benefits will only apply to them. However, the company seemed to suggest the blur characteristics of other lenses could be included as built-in profiles in future Micro Four Thirds lenses from other makers.

It provides faster autofocus.

400mm equivalent on a 1" sensor with a 2.7x crop is an actual focal length of just under 150mm compared with 75mm on the Sony. That means that the diameter of the front element is going to be 75/2.8 = 27mm on the Sony and 150/4=37.5mm on the Panasonic.

So the Panasonic lens will be double the length of the Sony's when fully extended and have a front element diameter about 40% greater.

Unless there is an error in my calculations (which I am sure somebody will point out) the lens on the Panasonic is going to be huge by superzoom standards.

(My paragraphs got squashed up when I first posted this!)

I definitely agree that the max aperture will become smaller fairly quickly as focal length increases...

I agree and this is from a rumor site. But we know this.
  • The 1 inch sensor will perform better than the LX7 sensor
  • All recent Panasonic cameras focus quickly and DFD will improve on this
  • Panasonci video is always good and this is 4K
  • 400mm
I don't know the price and that is a BIG question mark. I kind of hope it is NOT weather-sealed keeping the price down. As a super zoom I woudl guess the lens will perform as well as the FZ200 (though it is shorter).

I am thinking of this camera for all-purpose stills and video. It won't replace an ILC and won't be as flexible (F/2.8 on 1 inch sensor = not great for low light), but for most people it will be fine.

So right now I say, Zowie!

The FZ1000 sounds very interesting. Especially the 0.09 second AF That would be a big improvement over the Sony RX10.

I have the Sony RX10 and I find it is poor as an action cam for taking photos of my children 8 and 10 being active. Zoom is slow, too much time between photos when the screen is black. Too much shutter lag. I end up with lots of photos with just a tennis shoe or an elbow in the edge of the frame. My Sony A65 with 18-135 works great as an action cam and it covers the same focal length range as the RX10. The A65 AWB leaves a lot to be desired though.

I've got to say I think Panasonic still need to work on DFD a bit, I do run across situations where my GH4 focuses less well than my GH3 would have and a lot worse than my 5DmkII (not noted for its World-class focusing, but surprisingly good a lot of the time). However I do feel the tracking is a step up from what came before, which is the big plus. (It really really doesn't like focusing on certain things on water though, first ducks and today eights, mostly very blurry eights.)

If there is not too much contrast it still loses track. And in the evening with the 35-100 and video it focusses to some point and then refocusses. Just a wobble, but at day it is doing it clearly smoother.

AF-c is simply in a class on its own compared to all other CDAF baseds systems and up there with PDAFOS.
 
When it's good, it's good, but it's still "not good" just too often for me personally...

(But I'm still glad I bought a GH4, even after Panasonic said the Sony sensor in the GH3 was actually a bit better than the Panasonic sensor in the GH4.)
