LG G2 Makro lens

Hello!
The LG G2 has an exceptional camera, we all know that. So to take even more advantage of this I've made a makro lens that you can 3D print yourself. I just wanted to share this with you guys, I hope you like it. More sample pictures and files can be found on thingiverse
Because of me being a new user I can't post the link to it, but go on Thingiverse and search for samsve (LG G2 Makro lens)
Best Regards
Sammy

I wish I had access to a 3D printer though

Thank you!
To be clear on one point, the case is 3D printed, but the lens is from a "copier laser assembly" but you can find these types of lenses in every laser printer!

Very useful
Great man I could use this for an image proyect right now, massive thanks

Thanks for the heads up.

Is this really a macro lens (bring far object look [email protected]) or is it micro lens (magnifier for close-up imaging)?

i guess you've messed up the terms...
1st lens you are mentioning in your post is called "zoom" or "tele" lens
2nd one is called "macro" or "close up" lens (not micro)

Any tips where to get nice macro (or micro, whatever) lens? I was using some lens from cheaps ebay lasers along with my old compact camera, the zoom was really huge but on the other side the quality was really poor. I've also got there some camera lens from Smena 8M and Zorki 4 (Industar 50 lens) but since I don't want to destroy them, I can't really use them for macro (or micro, whatever) (even when reverse mounted, not that much zoom).

most of the macro add-on lenses (or any add-on lenses) you can find for mobile phones are basically the same, cheap ones - good for fun, but no good for anything serious...
only thing that comes in mind is that sony standalone lens that can be used on any mobile device
like this one
http://www.wired.com/2014/09/sony-ilce-qx1/
but for that price (or if you add some extra $), you can find a better compact camera (like one from the Sony NEX series or Olympus Pen series)

Oh thanks for correcting me though. Btw, is this lens for zooming or macro? I really wanted, well at least 50x optical zooming capabilities for my project. Not really interested for close-up shot since i've made my own by just using cd-rom lens. Its not perfect but, well it does the job.

lol... you will hardly find 50x optical zoom lenses even for dslr cameras
if you need that much optical zoom - you better forget about mobile device for doing that...
you'd be better with the FinePix SL1000, Sony HX400V, Olympus SP-100, Canon PowerShot SX50 HS or several other compact cameras which will give you 50x optical zoom and way better pictures than any mobile device for sure...
ps:
you can also search for a cheaper dlsr that you can attach to a telescope with a proper adapter... i believe there are some budget solutions for this combo

Yeah i know it is ridiculous to even begin with. Lol. It is just i am very interested in this kind of thing. My brother just got me 200x telescopic lens for my d90 and i started to see a whole new things to fiddle with. It is amazing!
Beware ladies. Lol. Just joking. Dont ever do unethical things like peeping tom could. Even if it fun.

believe me - macro lens on phones are PITA to use... especially if you don't have a dedicated photo capture button on your device (and G2 doesn't have it - at least not on the bezel side instead of the buttons on behind of the case)
you can grab a macro lens from ebay for as much as 10$ or less...
downsides are:
- very hard to focus due to being unable to keep the device steady that close to the subject (and you have to be very, very close to the subject to get it in focus)
- on G2 - the macro lens always has a black circle vignette around the image (lens hardly covers the whole frame without the vignette "effect")
- not so sharp images as the real macro photos
- a bit clunky to use because it clips on the device (instead of screwing to the case like i.e. on iPhones)
good points:
- nice for fun (especially if you don't have a normal camera - dslr or compact)
- gives almost a natural bokeh to the macro image (which isn't possible with phone lenses)
my 2 cents

This one problem could actually be resolved by using voice-activated command on G2 stock camera app. It is called cheese shutter and this function is pretty great though.

Yes without a tripod the image would susceptible to blurring. Unless it can take picture at 1/1000s at lowest ISO possible without darkening the picture, yes you wont get professional-quality close-up shot.

Those picture actually very nice. But the problem i spotted is there isnt enough lights. I used to take pictures like those but end up having to bring the camera too close to the object thus blocking lights to shine the object. That is the only problem for this method. At least for me, it is.

Front Camera Quality

Hey everyone,
Is someone able to speak to the quality of the front camera on these? I have the HD 8, the front camera is advertised as "HD" (probably 2 MP) and performs surprisingly well.
I'm curious about the quality of the front camera on the 7. It's advertised as VGA, so probably .3 MP. I've used some of the low end Dragon Touch tablets with .3 MP front cameras and the quality is *terrible*, it easily took 5+ seconds to focus on anything. But part of that could be the camera app, the manufacturer of the sensor itself or something else to do with the quality of the hardware.
At $150, the HD 8 isn't prohibitively expensive, but it would be nice to get away with the $50 7 instead. The main functionality I'm looking for is whether it's able to focus in and scan a QR code (version 2 density) quickly.
Thanks!

Just tried it. The front camera takes the photo fast enough, but the image is very smudgy and a bit too high contrast. It's VGA. It would be ok for video chat in a well lit environment but not for much else. If you're one of those 'selfie' types, you'll want a different camera. :laugh:
The 2mp camera on the back seems to be a bit better, but then it should be. Needs to be changed to 4:3 to use the full sensor, as it defaults to 16:9. The HDR mode improves picture quality by a fair margin. Especially unintentionally overexposed ones. As with all these cheapo cameras you will have to hold the whole device still to get a clear shot.
Neither camera is anything special and I'd say both are below average. The 1.9mp camera in my Samsung Gear smartwatch is leaps and bounds above the image quality of this Asus Fire tablet and it's 2 years older with a similar lens size.
The app for the camera does the job but is very basic with few options to change.

Really two cameras ?!

Hello guys, I'm really disappointed and I need your explanations please !
I bought my Galaxy Note 9 (960F variant) from an official Samsung store so I'm sure I'm having a genuine one
As you know, there are two cameras in the rear. I thought that the main one is in the middle, and the 2X optical zoom powered is the one at the left.
Well, yesterday I was playing with my phone, and I masked the camera on the left with a paper. So I thought that I can take pictures in normal mode with the camera on the middle, but the 2X option should give me a blank picture only because of the mask. But no ! Both modes (1x and 2x) are using the same middle camera !
It's normal ?! So what is the purpose of the left sided camera ? Is the 2X really an optical zoom or just a software one ?!
Please do the test and answer me !

Maybe this explains is it
https://www.trustedreviews.com/reviews/samsung-galaxy-note-9-camera

My side camera works only on live focus. Everything else I tested works on the center only. I have a snapdragon, the same setup as my wife's Note 8 too. It's the way they are designed.

It's the same thing with the Note8. It all depends on the lighting and if anything blocking the other camera. It works by design. So when you hit 2x it seems it's blocked and gives you 2x digital zoom instead.

So it's truly an optical zoom ? I ask because if it's "just" a software one, I won't never use it to preserve picture quality !

yep, AFAIK, it is true optical zoom. The camera just changes back to main camera if something is blocking the secondary one.

There are no official specifications from Samsung explaining the purpose of each camera ?!

It depends on the lighting
Try and go outside, on a sunny and bright day, point at the clouds or something, and zoom
Then cover the center camera, it should be using the 2x lens (can confirm with my SM-N960F)

You didn't, it's working properly. You are just confused. Cover the middle one and see. Take multiple pics @ 1x and then at @ 2x on both cameras with and without covering. Covering the camera just out it into a different mode so as to not take bad pics by default. The difference is clear of you understand the 2 technologies and have any eye for photography. It's working completely correctly and very nicely.

Yeah like the others stated, it's not supposed to work completely independently and take pictures even with no light to the sensor, it's supposed to be smarter than that, if it's working correctly.

Hey all, I worked this out.
In a low light situation the wide camera is used for the 2X zoom (So technically Digital zoom)
In a situation with more light, it switches to the dedicated 2X camera.
You can test this by putting your finger over the camera and showing it a bight light, then dark. I'm guessing this is because the main (Wide) camera is better at low light.

Yes, although you mean digital zoom for low light situations.
My issue is that sometimes the camera still decides to use digital zoom in good lighting instead of the second camera because it decides that a slightly overcast day or sunset is "low light" or the subject is too close. I'm guessing the second camera can't focus as closely and its optics aren't quite as good as the main camera. In more inconsistent conditions I can sometimes see the viewfinder image jump between the two lenses and usually settle for the digital zoom. Doesn't seem to be used at all in Pro Mode. (I also wish Pro Mode had burst capture)
If you look at the EXIF data you can see which lens is used for your photo. The wide lens is 4.3mm and the telephoto lens is 6mm. The mushroom images were taken 20 seconds apart with "2X" in Auto mode; in the second shot the camera decided to use the wide lens with crop, and the EXIF shows 4.3mm compared to the first image. The crop version just looks like an upscale and has more aggressive nose reduction and edge enhancement; it's not too bad compared to some phone cameras which add too much sharpening or use a simpler interpolation filter. The third image of the grasshopper/locust was in very bright daylight, but the camera decided to use the main camera with 2X crop.
https://imgur.com/a/MYpRogb
With video it tends to be even more obvious which camera is used because if you take 4K in low light with 2X enabled it looks more noise-reduced and interpolated.

I get that Samsung tried to make its camera app "smart" but the 2x button implies that it's using the 2x lens and doing otherwise is deceiving.
If I knew that a zoomed photo would use digital zoom then I'd rather take the full shot and crop later so that I can have more flexibility in framing.
While this is unlikely to ever happen, here's how I feel this should be fixed:
1) Add an option to force switch cameras in all conditions (perhaps in pro mode only?)
2) Hide the 2x button unless the telephoto camera will actually be used. Still allow pinch to digital zoom.
I've looked around but couldn't find any 3rd party camera apps which are able to use the zoom lens. Does anyone know of one?

I've tried a few shot it seems if the lighting isn't good enough it will stick with the primary camera., in good lighting it does work though.
Just do two shots with each and compare the level of detail, it should be obvious.

Wide angle front camera?

Has Anyone else noticed that the front camera is capable of taking much wider picture? ?? if you switch mode from SELFIE to Wide Selfie, you'll notice that the camera is capable of taking much wider angle picture. wonder why sammy didn't use this? regular SELFIE seems to crop significant amount of picture..

The front facing camera is usually used for taking photos of your face, this is why, by default it is set to normal mode, not wide.

Yeah that's been advertised since about two notes ago.

But you have to pan back and forth in wide selfie. Like a panorama.

i understand you have to pan it back and forth, but even not panning it's still covers wider angle than just regular "selfie". it would be nice to be able to capture wider on front camera. which is what Pixel 3 is doing.

Gotcha, I just tried again with the bottom camera covered and the zoom works right up to 3x, anything over 3x and it goes black.

I have the same problem, no optical zoom, but the main camera do a digital zoom.

Here is a demo of the cam problem at 1:23 min
https://youtu.be/UHCS4iKEmYc

Mulitple things going on here. First off the camera switches between the normal camera cropped for 3x to the tele camera depending on the lighting condtions. You can test this yourself using different lighting conditions and your finger in front of the various lenses. Second, in order for the lenses to be 3x optical, the tele has to magnify 3x closer than another lens. All the reviews cry foul because the tele lens is about 2.2x optically stronger than the normal lens. It is however about 2.9x stronger than the wide angle lens.
So, everyone is arguing about what the optical zoom range is. My result is from my actual personal result testing output images from the cameras. In looking at this, I ignored cropping and varying MP of each camera. I believe the total zoom range of the system to be 3x.

This was out 3 days ago. They've already got responses from OnePlus. It's a 2.2x optical zoom. It's in the post processing that they crop the image to make it 3x. It is 3x lossless zoom actually. So it's just as sharp and no degradation of quality.
To me, the image quality is the same so it really doesn't matter much how they get it to 3x as long as it's lossless it's all good

This made me smile as the photo quality is really extremely sub par, without using GCam that is,
Unless one is into water paintings, in that case this phone is a must have.

You can but I don't have time or the energy to explain it to you.

The whole measure of "x times" zoom is marketing nonsense to begin with. All this means, is a ratio of that particular lens' longest focal length to its shortest focal length. It doesn't really mean much. For instance, my 70-200mm DSLR lens "only" has a 2.8x zoom. Yet the "reach" of this lens is so much greater than any smartphone, that it is comical to even compare the zoom this way!
This "spec" is only useful for folks that compare and buy things based on those specs (or companies to market to such people), instead of real world experiences. The phone takes some nice pictures, and happens to zoom and do some other useful things. That's all I really care about.

The zoom focal length is also not of much use without knowing the film or sensor size. It used to be that cameras all shot 35mm film and the focal range meant something. Today a 70mm lens is quite worthless shooting indoors compared to the wide angle on even the 7pro.

A full frame DSLR sensor measures 35mm. The focal lengths for full frame DSLR (and full frame mirrorless cameras) lenses still mean the same as they always have. Even on smaller sensors for "real cameras" the focal length is still meaningful, if you take crop factor into account.
The tiny sensors (around 4mm) on smartphones are a different animal. The focal length on these smartphone lenses are around 1-4mm. They often speak of "35mm equivalent" focal lengths when looking at camera specs. But it's a bit ridiculous. The fisheye affect is so drastic at such a focal length, that there really is no "35mm equivalent" not matter how small the sensor.

That completely depends on your subject matter. I usually photograph people (face shots). The 70-200mm lens rarely leaves my camera, indoors or out. Many portrait photographers will tell you the same. 50-85mm is the minimum focal length considered acceptable for portraiture (not making a person's nose look huge, for example) by many photographers. Obviously, that range is too long a focal length for things like group shots, whole rooms (like you example) etc. But that is what interchangeable lenses are for.

Yep and since you can often swap full frame lenses into micro formats there is really no assumption that can be made other than the overall range of a lens.
It's ironic that selfie cameras are probably the worst equipped to shoot people. Smart of OnePlus to use the back tele lens for portrait. In effect the 7pro has interchangeable back lenses. Still not what my dslr or high end compact cameras deliver but impressive none the less.
