On article Choosing a camera Part 2: is a bigger sensor better? (416 comments in total)
In reply to:

xPhoenix: Once catch: cropping. If you ALWAYS crops to DX size or smaller, then you're better off just using a DX camera. Yes, the FX has a larger sensor, but you're throwing half of it away by cropping. The smaller sensor actually has a higher pixel density, so you're putting more pixels on that small bird or whatever.

So, if you can get close enough to fill the frame, then I'd agree that the bigger sensor is always better. Of course, just ask a wildlife photog if they can always get close enough =)

OTOH, now that we have cameras like the D850 and a7riii, that have virtually the same pixel density as the crop sensors, I prefer to use high-res, big sensor for everything.

Nice series, Richard! I like that these article are short and concise. These topics have been discussed ad nauseam on the forums, and many of those threads devolve into bickering and insults. It's nice to see you explain it here clearly without getting too carried away with all the minutia.

But camera with that many pixel for cropping would usually be too slow for capturing fast subjects. We usually want more frames than more cropping space for moving subjects.

On article Gear of the Year 2018 - Dale's choice: DJI Ronin-S (36 comments in total)

What makes Ronin-S better than other gimbal is its high payload, and its ability to handle an unbalanced setup.

The motors are powerful enough to use both end of a zoom lens without changing settings. With 12-60mm lens the camera is perfectly stable, collapsed or fully extended. I can use the accessory focus motor to control zoom while recording.

The only problem is: it is exhausting to hold the whole thing one-handed. Can't keep using the wheel for a long time.

On article Review: DJI Ronin-S gimbal stabilization system (66 comments in total)
In reply to:

Imjustagirl: What if your camera & lens already have stabilization (such as the Lumix G85 w/2.0 lenses, claiming 5 stops of stabilization). Would you shut down the camera & lens stabilizers to use this Gimbal? If so, is this considered better as a stabilizer? ...Angie

In practice, I like keeping the IBIS on. No downside other than draining batteries. Helps a bit with joystick movements. (I use G85 and GH5)

SmilerGrogan: Does anyone know what exactly is in the huge amount of information being transmitted between lens and camera? Beyond the identity of the lens, aperture and distance, I mean.

The position of the IS elements of the lens. With the information, the camera can apply digital stabilization with better precision.

(unknown member): What software was used and what do you mean that the editing was complex compared to the GH5? :)

Everyone loves Fujifilm's ETERNA look. The official LUT pack is a great starting point:

I think it means the amount of grading that has to be done after applying LUT for F-log and V-log, respectively. Even standard looks like 709 don't always look natural.

In reply to:

pro photo 2011: In the Video review section, under Key takeaways, the 4th and 5th points are contradictory.

4th: Utilizing the in-body image stabilizer does not give an additional crop

5th: Digital stabilizer crops slightly, but without noticeable detail loss

It is called "E-Stabilization (Video)" in the menu, which can be set to ON or OFF even when Dual I.S. is activated.

Panasonic had: 1. in-boby stabilization, with no crop. 2. in-lens stabilization, which is lens dependent, and becomes dual-IS when paired with in-body stabilization. 3. electronic stabilization, which can be activated in addition to the IBIS for even smoother video but at the expense of 1.1 crop.

On article Shooting live music with the Panasonic Lumix GX9 (143 comments in total)
In reply to:

vikingdescendent: The only thing that works for me in a live music scenario, is shooting 4K vids, especially at night, where the lighting changes from one second to another. Besides, the music is part of the show, why delete it by taking pics? Samples at the 2018 Montreal International Jazz Fest in 4K, a6500 and the Sony 18 to 55 mm f 3.5 to 5.6, using Clear Image Zoom www.youtube.com/watch?v=qGOm8RdSsWo EPZ also the 18 to 105 mm Sony EP Z 18 to 105 mm f/4 G lens www.youtube.com/watch?v=Wt2x2YmK6wU

I think most independent bands/artists like short clips, provided that you: 1) talk to them before putting clips online, 2) add proper credit, 3) get nice audio, and 4) most importantly, they did not make mistakes in the video.

The hard part is getting a good balance of music, vocal, cheers, and background noise. Almost impossible if you ain't working with the band/organizers.

Video quality? They don't give a

On article Video: is the Canon EOS M6 good for vlogging? (14 comments in total)

I am not a vlogging but it is nice to see content with specific usage in mind.

The video AF is really effective! If Panasonic has this kind of video AF, I would definately use AF in some situation. But for now, I would stick with MF, with IBIS and 4K.

Treeshade: In Hong Kong it is called GF9 (but we have GX85 and G85 like US). The GF line is still quite popular in East Asia. I think these small selfie cameras are better than smartphones in some areas. The IQ difference is noticeable even for casual users. Plus, they are cheaper than high-end smartphones.

It would be interesting if Panasonic could make a 21mm prime, like the Casio TR fixed lens compact. Not only it is ideal for selfie, it is also a great for indoor and wide scenery.

Yes I am talking about 21mm equivalent. I have the 14mm pancake plus 0.78x wide convertor, which is about 11mm (22mm eq.). I really like the focal length for videoin 16:9.

It is quite difficult to go beyond 24mm equivalent without being heavy and slow. The Fuji 14mm (21mm eq.) is large and expansive. Perhaps the m4/3 version could use a modest aperture and a little software correction to make it small?

Sergey Borachev: The FujI A3 is so much better for just $50 more! It has larger lenses and no 4K, but seems better in every other way, including 24 MP and larger sensor, natural JPEG colour, superior IQ, much longer battery life, solid build, twin control dials, video with exposure control, built in camera grip, much better flash sync speed and hot shoe.

For the targeted buyers, the natural JPEG colour should be very important. And for any of those casual shooters who do dabble in RAW and find its XTRAN sensor tough, there's the cheaper X10 with its Bayer sensor. Unfortunately DPR do not review these really interesting Fuji compacts.

Fuji needs a tiny pancake zoom if it wants to win customer in this category. It is too bulky for casual users.

If GF9/GX850 has Fuji color it would roll over this market segment.

Raist3d: Dpreview - you have completely ignored the awesome street photography use this camera provides. And as for action- it shares the DFD of the gx85/Gh4 and can do some reasonable tracking.

You also seemed to miss (maybe I did) the double raw buffer over gm5. The camera operation that's so fast and as for lack luster color, did you try vivid with some contrast and saturation? Or standard? I find that at night it can work well.

I use GX85 and its AWB is much, much better than older GF and GM. Some skin color problem are still there, e.g. zombie green skin indoor, but at least JPEG is now usable.

I noticed the improvement when I upgrade to G7.

In reply to:

Franz Weber: So the takehome message is:
The GH5 is a very good stills camera, but the lacklusting video AF makes it not the best choice for videographers.
Panasonic will fix this somewhen in the future, but until now they have no clue how to do it.

I use MF most of the time (for event, interview, performance), but I would really love better AF.

When I got my G7 I was impressed by the DFD AF. When I want to switch target and nail focus in the shortest time, I could drag the touchscreen and the AF always hit with no hunting EXCEPT the CDAF back-and-forward move to confirm focus. It is fast but still noticeable.

I think AF could be part of the creative tools and it would be even better if it could confirm focus with less focus shift.

Cary Knoop: From the article: "4:2:2 10-bit codec is 64x as much data as before"

No it isn't!

10 bit is 4 times as much data as 8 bit and 4:2:2 is 1 1/3 times as much data as 4:2:0, so it is 5 1/3 times as much not 64 times as much.

It is not 64 times. Each pixel has 4 times more data but the number of pixel is the same. But even with compression that is 4 times more data to compress.

Is the 1080/50p oversampling from the full sensor width?

If it does, then it is a much better option for FHD output (compared to downsampling UHD/50p, which has good IQ but is very time-consuming)

In reply to:

(unknown member): weird.. how can you increase the overall market by targetting enthusiasts and professionals that ALREADY HAVE cameras..

Perhaps they could lure professionals to spend more money on a second system? Like switching from 1/1.7" compact to RX100 and RX1.
