(Q) Slow Autofocus

Hi guys,
I've noticed it's taking a good 2-3 seconds to focus before taking a picture - is there any way to speed this up? I thought the laser focus was meant to make it pretty instant?
Thanks!

I've noticed it too. It is a bit frustrating
When the conditions are good (nearly perfect), it takes the picture instantly with good focus/quality.
Often if I take a portrait of my girl, it takes a long time... OK, maybe it's because of her :laugh: Seriously, it seems that the autofocus doesn't know where to focus (background or foreground).

If it's having trouble. Does tap to focus not work?

That's the one I've been using, literally just tapping to shoot. Not sure what's causing the delay...

same here
my autofocus is off cant get faster shooting of camera... how to fix this?

Really need help with this too!!

Check to see if HDR is on. If it is, turn it off and try again.

Didn't work

Tried that and no luck.. Even factory reset the phone and no joy..
Emailed LG support for advice.. I guess I am keen to know if anyone in low light can take several photos one after the other?? Mine has about 3 seconds gap between each photo for indoors shots!!
James

Is there a solution to this yet? I have tried the cyanogenmod camera on my G3 and the speed of focus is amazing, but photo quality is not good enough (I guess this does not use the laser autofocus either).
really just want the G3 stock camera to take photos quickly indoors in low light??
Any ideas?

[Q] LG G3's HDR mode on is taking only one photo

Hi,
While playing with the LG G3's HDR mode turned on, I realized that it takes only one photo. Should it not take multiple(two to three) photos at different exposures(high and low) and then combine those into one?
Thanks!

It does take few shots with different exposures, it just does it relatively fast and the outcome is 1 photo. LG has done pretty good job with HDR if you ask me.

Perhaps the laser focus comes into play and things happen super quick!!! :cyclops:

[Q] Is there any solution to very slow autofocus?!?

My LG G3 has very slow autofocus, sometimes it needs 3-4 minutes to autofocus, why? There is a solution?!?

Mine is lightning fast. What you say doesn't make sense.. Are you sure you're not using a case that's blocking the laser focus on the back?

Sorry... but 3-4 minutes? you sure? that sounds very strange...
do you see the laser light? do you have the same problem in plain light day? sorry for all the questions but it's just that 3-4 minutes sounds really strange, :S

It's like a "cold" autofocus/camera app open problem: it takes long time to focus for the first time but then it is very fast until I close the camera app. If I close the app, the autofocus need time to re-work correctly...

Have you checked if exist any protection plastic in it?
My friend have a g3 more than 3 months and he never notice that .. I needed to get their MicroSD and I see it and removed
Its a very tiny blue plastic.

LG camera raw question - for photo enthusiasts

Hi one of the reasons I'm interested in getting a LG G4 is because it can take raw pictures. There are a few things I'm wondering:
1) Can raw pictures be captured with third party apps?
2) I'm interested in using an external DSLR flash with the LG G4's camera. I wonder if it's possible?

1. The app pro shot can capture raw and does a better job than stock. Search the photo thread for pro shot. But it won't give you a shutter time longer than 0.5s. No 3rd party app will allow 30s shutter.
2. you require a flash with an optical trigger. The external flash has to be setup as a slave. This means looks for a red window on a flash and the idea is the flash on the G4 triggers the bigger flash. Do test this out some optical triggers are more sensitive and will work others won't. Unfortunately led flash on the g4 isn't as powerful as a zenon.
let us know if you find some thing that works. Can get some cool water splashes

I don't think phone LEDs will be powerful enough to trigger my nikon external flashes. I've seen some audio jack converter triggers but they're, unfortunately, exclusively for the iphone only.

Try with different flashes, some might work.
Distance of flash to G4 will matter. Close enough all will work. Question is what is your minimum distance.

Apps for iphones include:
isyncflash
triggertrap (lacks a lot of features on the android version)
not sure about android...

Since I have a few flashes, I can get one of them to be as close to the LED as I can...

All speedlights.
How close do you have to be to trigger them ?

phone can be a few cm from the closest one. if one speedlights fires then all speedlights will fire.
I hope sync won't be a big issue since i'm talking about ~1/30s shutter speed

i'm asking when you tested with the nikon flashes how close the G4 needed to be to actually get the nikon flash to fire.

There's some confusion here. I haven't got the G4 yet, I'm just constructing a list of what accessories to buy...
So I'm the one asking the question! Though my experience with other phones plus some googling tell me that the LEDs probably won't trigger the speedlights at all...

ok, have you tried with any other phone that has an led flash to get the speedlites to trigger. How close does the led have to be.
if that works then g4 should as well.

Mmm, I wonder if optical trigger would work. Smartphone LED flashes are long duration, unlike real camera flashes, so I have to wonder if they would trigger in sync with exposure...
As mentionned in another post, you could check Triggertrap, but on their site they do state that Android doesn't work too well, and their flash trigger isn't compatible with some Nikon flashes either (do check).
Anyway, how would you use your Nikon flashes? Seems rather cumbersome, you might as well use them on your dslr with an eyefi card and transfer afterwards to the phone.
If you are interested in offcamera flash, the iBlazr2 bluetooth LED flash could an interesting accessory, much more portable than a SB flash:

Since I have a foldable umbrella with silver lining that I always carry with me in case of rain, I'm thinking of using it as a light modifier for softer lighting, hence a powerful xenon flash would be necessary.
After all, carrying a single flash in my bag + a phone is way lighter than carrying a DSLR+lens+flash.
Now it looks like the idea is getting more difficult to achieve without making my own electronics and coding my own app... I only intend to use the flash for stills. So a shutter of 1/30s will be fine and should be too hard to get the flash to fire within this long time..

Ok silver umbrella, nice.
I still think that syncing the flash to the camera exposure must be very tricky...
Syncing a continuous (led) light on the other side seems easier, as intended in the iBlazr2. I can see though that it is rather underpowered for your purposes.
Another similar yet more powerful option could be the announced Lume Cube: http://www.lumecube.com/
Obviously these devices are not yet out and there are no reviews.

Incidentally, since you are interested in taking photos in raw format:

<sigh> then that idea is out the window. Damn it! The camera is excellent but if only there were more lighting options.
Optical triggers on these flashes are programmed for xenon not led. and nobody makes an led trigger.
what about sound ? would a certain shutter sound be good enough. the flash will most likely be delayed though.
Someone made a bluetooth trigger for iphone
www.tricflash.com
only iphone as they don't have the budget for other devices. It's interesting they mention that the way the iphone camera works was the hardest obstacle. So no chance of this coming to android as cameras can work differently among vendors. Still people are sceptical that bluetooth is fast enough.
When i think back to videos i've seen of studio like photos from phones most were using continuous light. Since your shutter isn't exactly fast, this might be your best bet. I thought you were trying to go for faster exposures.
I got to try a galaxy k zoom in a studio setup once and everything flashed. The cheapest toy camera with a xenon will do it too.
Still the G4 camera interests me.

Hi! Well. It's not like you are walking around with all that equipment in your pocket? What's the real point.?
LG G4 has a great camera for a smartphone. But it's sensor is really small and nothing compared to even 6+ year old DSLRs. Why not get a normal camera for your fixed setup?

Shutter lag Exynos ?

Hi guys,
Anyone affected by a shutter lag on his Note10+ ? i'm using the Exynos version and the shutter is absolutely terrible. My S7 edge takes MUCH faster picture (both in low or high light) ! Same with a S9. I'm very disappointed by the camera tbh..
Anyone in the same situation ?
Thanks.

Well, no, in normal light conditions, it is instantaneous, in low light it obviously takes as much time as required by exposure metering

Obviously day light picture will take less time to be taken than night picture it's not my concern. But than why is a 3 year old and 1 year old phone takes faster picture in similar condition?
And If I press twice the shutter button it will only take 1 cause it's too slow to take the other one.

I do not have this problem either.
Do not save to SD card, use internal storage. I'd guess that is the issue.
Internal is much faster and reliable.

I use internal mem to save pictures, which is faster than any sd card, but, even in not so bright conditions, the camera is blazing fast, only in real low light is when takes longer, but again, in really low light enviroments

I'm not using the SD card I don't even have one actually.
I'll update a link you guys can watch it
I took the video this morning 10am.
You can see 2 things the small lag (much bigger in a less light environment) when I push the shutter and 2 if you push twice it will only take 1 picture.

Did you have a look at shutter speed?
In low light it sometimes fall down to like 1/10th shutter speed (to decrease ISO). Maybe in this case you clicked too fast before the 1st shot ends.
I do not feel like it really happens to me.
Did you try to just stay pushed down ? It will take a serie of photos (enable it in settings). No point clicking twice in a row then.

I've checked the shutter speed (not the same condition as this morning), I've tested at 1/20 and 1/45 still slow. I've noticed something tho, by visiting the pro mode to see the shutter speed iI've put everything in auto (ISO, focus, aperture, shutter speed) and It takes way faster picture than the photo mode.
And yes if I push and hold the button it will activate the burst mode and take plenty of picture.

I'm having the same problem with my Note 9; I thought I'm just being paranoid, but when I compared it to my S7 - the shutter speed is way better than the Note 9.
The same goes when I took photo in pro mode - the shutter speed became faster and better.

Winol is correct, for speed use internal memory.
-&-
Some of the reasons you buy a dedicated pro cam is fast boot, fast AF lockon, and nearly instant shutter release. Shutter release time is speced out with cams... in smartphones? Bah-ha-ha-ha
Smartphones don't have near the hardware, firmware, the display, the design, the raw processing power a pro cam has that's devoted to shooting alone.
The shutter lag is quit noticeable to me on all the smartphones I've owned including the 10+.
This is normal... it will cost you keepers but the control layout and design will cost you far more lost keepers.
No doubt in my mind about this.
Only a pro cam gives you all the tools you need to grab the most keepers; that's their sole purpose in life. Canon pro gear excels at it and are a rush to shoot with.
Street shooting with the 10+ (or any smartphone) is a slow motion horror story of lost keepers in comparison. Simple put... there's no contest.

i think the problem is with scene optimizer, once its off you get to take faster pics.
