Panasonic FZ1000 vs GH4 with 14-140mm f/3.5-5.6 (2): ergonomics



 The box arrived, time to put FZ1000 to the test against GH4 with 14-140 mm lens.

Body and handling
With matte surface finish, sharper edges of the top plate and massive lens barrel FZ1000 looks like the boss of the pack. Inclusion of the large lens has some consequences. Firstly, the camera is more unbalanced to the front and to the left. Cleverly, hand grip was sculptured accordingly: it is deeper (64mm vs 60mm on GH4), but with narrower ridge to increase space between fingers and the lens barrel. That makes the hand to claw slightly more, and the security of the grip is further improved by slightly bigger protrusion of the step at the fingertips. Secondly, tripod socket is offset from the axis. That is of course inconvenient for panoramas, but very bad for access to battery and card compartment – with most tripod plates it will be impossible without removing a plate first.
The rear part of the grip is in my opinion improvement over GH4: more pronounced ridge is further away from all the controls – I can see no chance of accidental pressing right D-pad button (moves focus point on GH4), and at the same time ‘Disp’ button is much easier to operate (required to reset focus point on GH4, to add to annoyance).
The dial is gorgeous. It is wider, with deep, square profiled knurling - it actually beats those of GH4. With its push-action toggling between main exposure parameter and exposure compensation, that makes it absolutely equal alternative to dual dial setup. The only improvement I can see is to reduce angle between clicks to allow for more adjustment during one move, or add some intelligence and when fast movement detected, to change full stops rather than thirds.
The 4-way control on FZ1000 is not obstructed by the grip, but the biggest improvement against GH4 are the buttons: they are bigger, with better tactile feedback, image review button of different shape (concave top) to easily differentiate from the other two. My only wish would be to swap (or allow to redefine) review and Fn3 (Quick Menu by default, used more extensively on FZ1000 due to fewer direct controls) buttons, so Q.Menu operations, engaging 4 way controller, could be quicker by cutting the travel from the button.
My biggest worry - focus point selection - is gone: I programmed Fn4 button (delete/return by default, kudos to Panasonic for using this button at all in the record mode) to invoke that option and it is actually even better idea than using one of the positions on the pad itself (like on some other cameras): no confusion whether pressing pad activates function or already moves the position, especially on ‘mushy’ buttons. If necessary, 4-way controller can be used for direct focus point selection.
Dial mode on GH4 is taller, more metal and has got lock, but for me neither of those make a difference. ‘C3’ position present on GH4 becomes ‘Scene’ mode on FZ1000: another hint of who are the two models intended for, and clever way of differentiating product lines and still sharing guts.
Strap eyelet on the FZ1000 is a letdown, being very close to the index finger – on GH4 it is moved further back, which is better position.


Display
Both cameras have display of practically the same size (FZ1000 62x41mm LCD 921K dots, GH4 63x42mm OLED 1036K dots - this one feels bigger, being flush with the frame), but it actually makes a difference: on FZ1000 it matches sensor ratio so the full area is used, on GH4 there are vertical bars at native 4:3 aspect for stills.
Touch control is a nice addition on GH4 with Panasonic excellent touch-control friendly approach. Apart from useful ability to select focus point/trigger the shutter, it includes 5 extra Fn buttons. In its creative movie mode it adds even more controls and also lets to touch-focus even in manual focus mode. For button-challenged there is tapping, swiping and pinching (where applicable) provided.
The display of FZ1000 is more accessible, with large recess to open it, and feels more robust as it’s got bottom edge covered by the body and display surrounded by a bezel.

EVF
Both use the same OLED 2.359 K dots panel, but optics on GH4 is much better: I can see the whole area sharp, whereas on FZ1000 there is smearing in the corners with eye centered in the finder, and when off-axis, this affects the actual preview. Also on GH4 the eyecup can be replaced

Flash
On GH4 there is a flush fiddly button, FZ1000 is equipped with much more pronounced lever. In both cases hood shadow is present until about 55mm (equivalent), there is no shadowing with hood removed at any focal length.

Lens operation
There are 2 switches on the side of FZ1000 barrel: Power O.I.S on/off and zoom/focus action of the ring. I prefer zooming with the lever, especially that it provides 2 speeds, whereas the ring seems to operate only proportionally to the rotation angle (about 160 degrees for full range) and it keeps being activated every time it is accidentally touched by the hand holding the lens (and the best support is right on the ring). The ring rotates smoothly with soft stops at the end of range. In the focus position the focusing itself will work when manual focusing (MF or AF+MF) is enabled. The lens retracts with quite audible whirr, internal mechanism* is also louder than on 14-140 lens (* initially I thought it was stabilisation, but it is audible with IS off. Then I switched AF off but it did not make the lens quiet neither. Both lenses exhibit that, just on FZ it is noticeable). Movie tests will show how it affects recording. 14-140mm lens have only Power O.I.S switch, but 2 rings: wider for zooming, with 90 degrees rotation to cover the whole range, and narrow focus-by-wire ring at the front. Focus ring moves smoothly with soft end stops, lens extension is a bit jerky (steep helicoid I suspect) – it doesn’t matter when framing for stills, but it is terrible if attempted to use during movie.

Battery
BLC12E of FZ1000 rated at 1200mAh (8.7Wh), BLF19E of GH4 at 1860mAh (14Wh). Apart from obvious difference in capacity, FZ1000 consumes more by driving the lens. I started a test, but I quickly got bored of turning on/off, zooming and pressing shutter button, so no results. Guesstimate gives FZ1000 half to 2/3rd life of GH4 on a battery. BLC12E full charging takes 2 hours, BLF19E - 3 hours, so it looks like they are charged with the same current.

Burst
It is one of more important features for me, because my subjects include 5 year old boy (‘action’ photography, spray-and-pray proves to be the best option) as well as trains, which often happen to be obstructed by trees and other objects and the best location in the frame depends on perfect timing or high sampling rate. Modern cameras seem to get better in that respect, however marketing is happy to quote just one number (rounded up, with compulsory ‘up to’ prefix), whereas the reality is a bit more complex. This summary should be self-explanatory though:
41/6.9s = 5.9 fps, then every 1.1s
42/7.9s = 5.3 fps, then every 0.95s
35/3.6s = 9.7 fps, then every 0.7s, then 0.9s
41/6.3s = 6.5 fps, then every 0.9s
6/0.8s (7.5 fps), 0.4 pause, 7/1.2s (5.8 fps), then every 1.8s
13/2.5s (5.2 fps) then every 1.8s
12/1s (12 fps) then every 1.4s
12/1.4s (8.5 fps) then every 1.3s

For the test I set my standard JPEG+RAW mode, if you save only one of those file types, expect some improvement. In both cases single autofocus, IS off, base ISO, super-duper fast card. In such conditions the results are about the best one can expect. GH4 is of course the king of the buffer, with about 40 deep bucket of photos. Speed-wise at M setting it is nearly there. At H it is just shy of 10fps, but when stopped down, lens aperture adjustment is the limiting factor. It is a bit curious, as focus and exposure are locked, so the aperture could stay constant, but clearly that is not the case. So if speed is what you need, open wide (that makes sense too) and you have a machine gun. Otherwise, settling at M doesn’t cap the speed much, and you gain live preview (frozen on first frame in H mode).
FZ1000 behaves a bit strangely: leaf shutter, acting as aperture at the same time, should not affect at all – but there is significant repetition rate reduction coinciding with aperture value. Then there is a gap (that is repetitive behaviour) at M wide open. Also card writes get faster at H, I’d expect the same write time from the moment the buffer is full. The buffer holds advertised 12 images, which at H wide open lasts for exactly 1s. I think realistically that is enough for a burst shooting – 4 times that, offered by GH4, is more important when there are consecutive series needed, so the top speed is maintained without need to wait for write to the card. FZ1000’s 12fps is very respectable figure, and even after stopping down it beats GH4. All that at bigger files size!
