[OnePlus 5T  Guides, News, & Discussion] subashchandran:
I expected a decent camera (having used a 3t before) and back then 3t could hold its own 70% of the time against the S7edge and iPhones, but had lacked the oomph/wow factor in the images it produced. The 5t is a huge improvement over 3t (I guess this is due to the fact that i did not use op5). The images are crisp, well lit and razer sharp in good to average lighting conditions. More often than not I have been mighty impressed with the OOB images from the camera and I have not been editing them on snapseed because I didn't feel the need to - thats a testament to the camera processing on this phone (OnePlus has come a long way here).

Good lighting:

Moderate/Tricky Lighting and conditions:

I expected things to go down south as it did on the 3T on similar lighting conditions. Seattle is a particularly tricky place to get good evening shots as its mostly grey and gloomy and camera's dynamic range becomes a big factor when shooting in Seattle. The camera did a good job detecting the need for HDR on the streetcar shot below (It notifies on the camera UI that its using HDR). Given the gloomy and dim conditions I was very impressed with the picture. I was unsure about composition when the streetcar was moving so I long pressed the shutter - With HDR on, it took about 4 shots in very quick succession (Thats impressive speed, slightly better than S7edge camera). The other 2 images below are in bright to moderately dim indoor conditions with multiple colorful stuff in the frame to meter. I have to admit that in indoor warm lighting the blue tones take a serious hit and ends up grey-er than normal. On the 3rd image below there was so many small tiny details on those objects and I was blown away by the sharpness and details on that image given that the lighting was only moderate.

Low Light and severely-low/dark lighting conditions:

I did read the op5 reviews early on and part of the reason why i skipped that was due to the low light camera performance (and lack of 18:9 screen). I wouldn't say they have blown me away here but I was getting more wow-worthy images out of this camera setup than the previous oneplus phones. 7/10 times I ended up not having to re-shoot the image or edit for sharpness and noise reduction. The first image below is a 7 AM (yeah thats how Seattle is in the morning) night lit building shot of the amazon bioshperes - the shot came out very very sharp and with excellent details. The lights were too bright so I am not surprised by the blown highlight spots, but the details on the greens/plants inside could have been better.

The next 2 images were taken in very poor lighting conditions. The first one is from under the kitchen cabinet where its the darkest corner and I know there is nothing going on here, but this is was shot i was MOST impressed with from this camera. there was absolutely no light in there but the outcome was a very pleasingly clear and crisp/usable image of my shiny cookie jar and hot chocolate cups.

The last one below is a photo with a faint one LED light source on a toy, i have linked the full lighting image for comparison of colors on the toy - in short: yeah it does better, but image processing needs lot of work on super dark conditions color noise and smudgy artifacts are visible.

Portrait mode and Macro:

This is an exciting feature and I was completely not expecting such results (DSLR-esque bokeh). Granted this is my first portrait mode equipped camera phone (as a daily driver), and I was thinking that the G6s wide angle was the best second camera option until this happened. I am going to let the sample images speak for itself.

In short:

Very pleasing subtle bokeh

Color rendition on macros is "phenomenal"

Sharp... sharp as a needle.

No glaring smudgy artifacts on portrait mode when lighting is good.

very close focusing distance

did I say sharp.. its freaking sharp - just look at the chipmunk picture below, those hairs can give you a paper-cut by just looking.
