Making the most of the iPhone, GX85 and GH5 and shooting in the real world

Here's the table of the 14-140mm lens.  The "Mid DoF" column is the DoF of a mid portrait shot (chest and up) and the "Close DoF" is just top of shoulders and up:

It's not constant DoF but it's pretty close.  

I then realised that for my environmental portraits, where I want the subject in focus but the background should at least be recognisable, I didn't want something that just had the subject floating in a sea of mush.  Also, nailing focus is more important to me than shallower DoF, and if the focus isn't going to get it perfect every time, and also pick the right focus subject each time, or if there are two people next to each other but slightly different distances from the camera because I'm not standing exactly 90-degrees to the line between them, then I'd rather the DoF be a few meters rather than the shot be missed.

(My bold) I agree - I'm often taking video of moving vehicles where I also want the background reasonably in focus to provide context for the image, so shallow DOF just doesn't work for me/isn't the 'look' I want.

(I also often shoot wildlife stills and video - the inevitable shallow DOF due to long lenses is a real pain to deal with when you might only have a few seconds to get the shot and there are tree branches/twigs in the way - which the AF prefers to focus on of course...)

One reason I often prefer the Pana 14-140 F3.5-F5.6 over the 12-60 F3.5-F5.6 (which I also own) is that the aperture drop off with focal length is slower over the wide to mid range - though the 12-60 is a bit smaller and lighter and much cheaper used.

 I don't know what the AF is like on the 20mm but all I do is frame up a composition, do a single AF-S via a custom button, then hit record and maintain the focus distance during the clip.

For AF-S, unless you're shooting really fast-moving subjects (sports, race cars, etc), nearly every AF lens made since 1995 will be fine.  Even stinkers like the Canon EF 85/1.2L are workable.

it said that Panasonics DFD sped up their CDAF, and I realised that I never see a CDAF Panasonic camera doing that thing where the focus racks the whole way to one end and then the whole way to the other end before acquiring focus, it just seems to do a quick jitter and it's done.  I never thought about that being DFD but I guess it is.

With DFD, Panasonic made AF-C CDAF about as good as it seems likely ever to be.  If not for the pulsing on still subjects, it would probably be enough for most projects.  My GH5 was always frustratingly close to being usable with AF.

Sure - people make a big deal of super fast apertures and extreme shallow DOF these days, but f/5.6 at 140mm is still relatively shallow, even on M43.  Heck, even the RF 800/11 has relatively shallow DOF on FF.

Yeah, it's definitely a case of "get the shot" first, "make the scene better by not making everyone uncomfortable" second, and "have a rig with a great image quality" third.

I'd add "Don't make yourself miserable by hauling around a boat anchor on a strap around your neck all day and night."

Yes, very much agree - it's why I don't own any huge/heavy long telephoto lenses even though I shoot some wildlife stills and video.

300mm on micro43 is close to the usable limit for handheld/leaning-on-something video even with Oly/OMDS levels of stabilisation, and you can get that with a relatively modest size and weight lens e.g. the Pana 100-300 F4-F5.6 is only 520g and 126mm long.

LX10 is a contender. That lens is pure magic. Ooc color is bland. The cam needs grading. Color is great with the right treatment, which it is in need of though, unless someone finds a way to make the internal profiles shine. In 4K it betters the HD G6 in lowlight, due to its much better codec and is close to a GX85. HD 24p is ok and pretty well resolved. HD 50p has very thin color, so use it only if necessary All in all highly recommended to be checked out by @kye  😊

Here is a clip during a lighting workshop I gave. Simple grading. I don't know what the crazy monologue is from, just in case someone knows German. It's really creepy.😊
