I was thinking about getting the 12-100 as my first lens along with the P4k. What is the net effect of this distortion? Worse image quality?

Have a look at the charts and you tell me.

But unless you’re shooting real estate, I’m not so sure how much it really matters.

Distortion can be pretty severe at some focal lengths, but a lot of zooms ‘as bad or worse’ than the Sigma 18-35mm f/1.8 in that regard have been a staple of filmmakers for forever - the Tokina 11-16mm f/2.8, for example.

Purists have always been pretty animated about lens distortion. Obviously any lens distortion with a film camera would show up in the print. With a DSLR the distortion would be evident in the viewfinder but could be corrected. With a mirrorless you can correct the distortion in both the viewfinder (with lens profiles) and the image (in camera or in post.) 

Obviously software correction of optical distortion requires a small degree of stretching of the underlying pixels which equates to some loss of image quality but it is relatively minor. I feel it is actually an advantage of mirrorless that you can effectively use both software and optical solutions to correct distortion allowing cheaper and lighter lenses (the FE 28 2 is a good example). Pretty much any zoom like an M43 12-100 or FE 24-105 will tend to have quite a lot of distortion at the wide end.

If the distortion is simple barrel or pincushion it can be fixed in most NLE's. Even if it's more complex it's likley it can be made good enough for most and unless the image has vertical straight lines near the edges it won't be noticeable in the first place. Additionally if you fix it in your NLE it will probably be done with less loss of quality than if it's done in camera as in camera processing has to be done with minimum processor load and not maximum quality concerns. There are other issues to be more concerned with over lens choice - focus breathing, MF action, Bokeh, CA and image stabilisation. CA can also be fixed in some NLE's or you can import clips into photoshop as a smart object and correct with the filters ( inc distortion). I've seen loads of footage on TV and in the cinema that has uncorrected CA and distortion which may or may not have been added to create a certain 'look'. A lens can also be technically perfect but this doesn't mean it makes for a pleasing image......

Indeed Webrunner5.  I'm waiting to see how well the existing ones work with this camera, for example will a new one be made, or will the x .64 one work, etc.  When reviewers or users here that already have a Speedbooster and report back on what works it’ll be easier to make a decision.

 

I'm using the .64 Speedbooster XL on my Pocket4K and it works great with full frame lenses.

There is a slight vignette on the wide end of my Sigma 18-35 1.8

I’d imagine someone soon will come up with a Heath Robinson, off the shelf contraption to boost battery life,  i.e. external battery pack or maybe a manufactured battery accessory, maybe fitted to bottom of cam.

Either way, will be popular.

Is the screen not that good even at 100%?

Yep, that what I'm hoping re: battery. Neewer or Meiki who make battery grips for DSLR's need to come up with one for the pocket 4k.

The one shoot I did with the camera was all in mid day sun and the screen at 100% was not good at all. That, and the fact it doesn't tilt are my major gripes with the camera so far. Overall though, it's a great camera and I'm really enjoying it.

It's a shame that BMD have thought to fit a nice large sharp LCD to the camera but then screwed things up by not having it be tilt-able a few degrees meaning I'm probably going to have to use a SmallHD focus or similar on it.....kind eliminating the point of the built in screen. 🤦‍♂️

Plenty of battery options already out there - Atomos Power station for instance. I'd just be using my stock of LP-E6 batteries and changing them as and when I need to as I won't want the bulk or hassle of an external battery. I wouldn't expect the screen to be usable in bright sunlight but it's highly likley various loupes and hoods are already in development to fix that.

I never said it wold cost more, it will be damn near as big. This is suppose to be a POCKET camera, not a Cinema Scope camera. And for 4 grand you can buy a real Cine camera used.

It's not really suppose to be a 'pocket' camera in the true sense of the word.......did you every try to fit the Kessler Pocket Dolly in your pocket?

In terms cine cameras that can shoot 4K RAW up to 60p, this camera really is 'Pocket' sized......but not literally if you get my drift.

Thing is A_Urquhart, no cam is perfect, but for the money this one has a lot going for it and it sounds like your having fun.

Of course Shirozina, any external battery pack will add bulk, but for me its also about having choices.  I already have 4 of these batteries.

Hmmmmm a 5" loupe? No thanks. 

I too am going to make a hood but that then means you need to hold the camera at eye height 6 inches away from your face which doesn't really lend itself to steady shots.

Why is a 5" loupe going to be no good?  My eyes can't focus at 6" so it's either a Loupe or an external EVF if I want to use it off the tripod (which I won't as that's where the GH5 is clearly superior.)

You are right, no camera is perfect but I think BMD tried to hit a price point with this camera that no one  really expected them or even asked them to.

Personally, if I had been asked how much I would expect to pay for a small camera with a 4K sensor that could shoot RAW and ProRes with dual native ISO's up to 60p, I would have said at least $2000.

If, at USD$2000 it meant that we could have a tilt-able screen....I would have much preferred that and it would have made the Pocket4K a much more polished and versatile camera. 

This is just my opinion after using the camera for a few hours and others may differ but ultimately, I'm liking the camera so not bashing it. I just think there is a slightly missed opportunity here that will make it hard to use the camera in certain situations that could have easily been avoided.

I just think a 5" loupe will be massive is size.

Doesn't look too big?

If you are concerned about size does this also extend to lenses? The 18-35 1.8 + speed booster is a bit of a beast....

Maybe.

Im thinking of trying an anti glare matte screen protector like those used on smartphones. Thoughts?

what's everyones battery plans so far?

At the moment I think I'm going to get a few LPe6 batteries and reply on the AC power for longer stuff. 

I've ordered 4 Wasabi LP-E6 batteries which come with 2 dual channel chargers so a can charge four batteries at once.

The battery supplied with the Pocket 4K is rated at 2000mah and the Wasabi's are rated at 2600mah so I'm hoping the Wasabi are true to their rating. I also heard the Wasabi's are coded like Canon's batteries so hopefully they will support the Pocket4K's percentage meter reading which should be more accurate and which the supplied battery doesn't. 

I should find out tomorrow.
