hello,
I own an HTC Touch Diamond and I need some technical information about the device. Specifically, I need the extended specifications for the main camera. And particularly the focal length of the lens.
I have searched the official User Manual and the web, but no analytical information was found. The only source that proved a bit helpful was the Service Manual that was found through the relevant thread of xda-developers. The problem is that in this document, more than one manufacturers are listed for that component.
Can you please provide the technical characteristics for the camera, or a link to a manufacturer and model no.
I am a research student and this information is vital for the progress of my project.
Any help or directions will be much appreciated.
Many thanks

Turn it over and read the text on the bottom!
hello,
thanks but the only information that is provided on the device is the Aperture (F2.8), the resolution (3.2 MP) and Auto-Focus. I am looking for the Focal length of the lens or some relevant info that will enable me to accurately calculate it.
Also, I believe the manufacturer and model will prove useful for further investigation.
Many thanks

I'm sorry, but F is for Focal lenght!
could we oneday mod for full 30fps vid on the diamond lik the xperia?
hello,
I wish you were right as you would save me from a lot of trouble, but generaly this structure symbolises the Aperture. If you are interested have a look at:
http://www.photoaxe.com/understanding-the-lens-focal-length-and-aperture/ or http://www.cambridgeincolour.com/tutorials/camera-lenses.htm
Do you believe that HTC may have used this conversion (F2.8) to describe the Focal Length, without adding the appropriate measuring unit (mm)?
Many thanks
Uhm....
I think f is for aperture
not focal length
It's totally different
Focal length like 50mm, 28mm, .....
always with mm at the back

Actually, http://en.wikipedia.org/wiki/F-number
I think you will find that the F-stop (F number 2.8) is the focal length divided by the diameter of the lens and not the focal lenght itself.
I know that the Touch Pro has the F2.8 on the case but believe the Diamond does not, correct me if wrong, does this mean that the Touch Pro camera is a little better?
A F2.8 is a pretty impressive apeture for a phone camera and I have found it to perform a little better than other 3.2 MP phone camera.
The US Diamond does have "F2.8 Autofocus..." printed on the back. I would agree that is likely an f/2.8 aperture.
Can't you just take a pic of a ruler/yardstick, etc at a set distance and calculate the effective focal length? http://www.giangrandi.ch/optics/lenses/focalcalc.html
I haven't used the camera much and I'm not too impressed. Outdoor daylight shots did, however, look pretty good and took enlargement really well. I apperently haven't matched up the White Balance and Brightness settings for very good indoor pics yet. Low light is just ok, despite my comment on the aperture.
As we all know the POCO X2 has one of the best sensor i.e. IMX686 for its main shooter but the jpg conversation algorithm of stock camera is not upto the mark. Stock cam images are slightly over saturated, Little bit warm in tint, and when you zoom in; the details of textures looks like oil painted and not that much accurate and sharp to the edges. Though its completely software dependant thing so can be improved.
Also front camera of POCO X2 is not upto the mark its having f2.2 aperture, due to which details and textures capturing is just average in selfies .
To enhance the camera performance of POCO X2 to get full advantage of IMX686 we can use GCam. As the GCam is modified application for few perticular devices it's hard to find the perfectly working gcam port for our device. (Though as per my observation on several popular smartphones, GCam ports works best on Nokia smartphones the condition is you should have to search a lot for perfect mode.)
For POCO X2 as per posted on Gcam Port Hub there are multiple working GCams available; but the problem is final image production from those modes are different, some are over sharpen, some are to soften, some looks too artificial, some are very good but poor in capturing details, some are good at low-light and some at daylight.
So as i tried gcam ports of almost all top developers on POCO X2; here are some of the versions that i found good in major aspects.
MGC_7.3.020_Parrot043-v2.apk
DMGC_7.2.018_ver.3.15.apk
HyperCam-RaizenA-10.apk
POCOX2_F1v9.6_6.2.030.apk
:
Also some users are using PixelCam_Plus_V2.0.apk and UltraCVM_v5.apk but i didn't find both of this that much good, might be I don't know the good settings for them.
For the 7.4.x version for POCO X2 i tried NGCam_7.4.104-v1.0_gcam.apk which is working fine and images of it are fine.
So if anyone find any other better GCam modes that are working good on POCO X2 then please share it in this thread. Also can suggest best settings, libs and .XMLs here.

Found this one on redmi 9's forum, valla! It works on redmi note 9 and it supports UW and macro. Got it tested quickly, concering the main lens it gives a pretty close results to gcam, almost the same. Ultrawide works flawlessly, it offers much better results than the stock cam. Night sight not efficient. portrait works fine. Front cam gets you better slightly better selfies than stock/gcam. A bit laggy but it's okay
*Note: you can switch to UW with 2X and macro to 0.6X*
Use it with the redmi note 9 config. /storage/emulated/0/trCamera/XMLConfigs/

Why samsung has disabled using telephoto lens for taking portrait. The same feature is enables for s20 model which has same camera module as s20fe.
Why don't you ask Samsung?

You are right. And we should close all the forums on the web, stop asking each other about our products and start asking the manufacturers all our doubts.

1. why ask something that only Samsung can answer?
2. if the colleague who posted the question had compared the specs correctly, he would have seen that the s20 models have a 64mp telephoto lens and the S20FE only an 8mp telephoto lens.
Before someone claims something he should inform himself correctly before posting something.
I think my answer to you also answers his question....

I am very much aware that pixel resolution of telephoto in s20 is more than that of s20fe and i meant to ask that in spite of telephoto lens why Samsung disabled this lens in portrait mode where as s20 has this. Even kids now a days knows that higher pixel resolution doesn't make photos more beautiful and s20fe shares more or less same camera setup wide,ultrawide and telephoto. I asked this in samsung forum and they never replied. I am thinking of some technical difficulties that force samsung to disable it. Thought someone from xda aware of this and that's why discussing here. if u don't aware of any particular details about this subject, why don't you ignore it since you have nothing to tell technically about this matter. do u think that due to 8mp telephoto, they disabled it. hope u are clear now.
The Fact:
S20 FE and S20 don't share the same Telephoto module. S20 FE has a true 3X Optical Telephoto module and S20 is Digital one, basically crop and image stacking to enhance the image output.
My Opinion: Maybe, it is the camera lens or image processing sensor. Or simply to create a difference, between a real flagship variant and flagship-like variant.

S20 is a also have a true telephoto lens with 1.1x optical zoom. I mean to say both have telephoto lens and why this lens is disabled in hyperlapse and potrait modes. As u said may be to make a difference with flagship they might have disabled same.strange is that Samsung provided costly telephoto hardware to s20fe which has 3x optical zoom and at the same time flagship s20 have only 1.1 x telephoto and just disabled a common software based potrait feature in s20fe telephoto

If you can't use S20 Camera at 1.1X zoom, then it's not an optical zoom. Whatever you use above 1X (other than 1.1X) everything is just digital zoom. It's not a true telephoto. Just for the papers/specs, it's called 1.1.. by adjusting the focal length by tiny bit or plainly not. But on S20 FE, 3X mode is the default Telephoto mode. So, it's purely truely optical.
Both modules are so different. Same module means same make, same Focal length, MP, F Stop, sensor size, pixel size, etc.
Yes, to differentiate the two variants should be the reason.

Ok.
Now S21FE 5G released with telephoto lens enabled in potrait mode. If the loic to to make differences flagship S21 5G applied , they would have disabled it in S21FE 5G as they did in s20fe. Don't understand the feature adding statergy of samsung S series.
It makes sense to Samsungs marketing department I'm sure. They call it differentiation of something like that. To us its nothing but bull****. Also disapointed with the lack of Raw support in Adobe Lightroom. Better get the base S-model next time if you care about photography.

You don't need to justify why you asked your question. There was nothing wrong with it. There are a lot of people on XDA that have insight on things like this.
I'd be more upset over the 1.1x zoom. At least 2x is needed to improve people subjects so 1.1x is pathetic.

Very true. All they do is exploit the high-res pixel counts. But it doesn't change the perception of the image. Focal Length matters when it comes to pleasing portraits. Many portrait photographers I know, choose the lens focal length between 50mm and 100mm. I would say S20 FE telephoto's focal length of 76mm (equivalent/simulated) is better for portraits (less distortion), close to natural looking faces. While the 1.1X zoom should be 30mm which is less than ideal for portraits, a wide angle, it would still have some level of distortion. Basically a gimmick, image stacking and croping the center of a high-res image. This is also the reason the subjects and their photos look different.

Keep in mind distortion depends on lens distance to the subject and not focal length. At the same distance distortion between the various lenses will be the same.
50-100mm are good for head and shoulder shots because they allow easier framing. That's it.
I too am disappointed that the telephoto does not allow for portrait mode because that is exactly where it would be great. Have to use 3rd party software to simulate it I guess
Maybe in some future software update
They recently allowed pro mode with the ultra wide which was not possible earlier.
Subtle differences between the s20 & FE telephoto lenses
FE : F2.4
S20 : F2.0 so half a stop wider than FE
FE: 3x optical zoom
S20 : only 1.1 optical zoom and the result is digital zoom
There is a slight edge in image quality with the FE here

Assuming you stil have the phone the one UI 4.1 update now includes the portrait feature in the Gallery so you can add portrait effect to any photo.
Take the photo in telephoto and then use this feature from gallery to get the portrait effect.
I just use gcam, or the new galay app portrait feature, whichever looks better. Then enhance by remini app, because 8mp is not clear enough sometime.
