What I'm sad is the shot of a red car that the S6 and G4 was better than the Z5.

anyway I hope SONY will let us control the shutter speed in the future.

The night shots I have seen taken by the G4 and the latest Galaxy phones aren't that great despite having OIS.
OIS in a phone feels more like a feature that gives tech-savvy people some peace of mind when taking pictures in a dimly lit conditions.

Read what I wrote on the previous page, OIS does help a lot.

Here are more photos, from a Polish tech blog, including some outdoor shots and indoor shots of the Berlin main train station. They are ok, but nothing stellar. There is a photo at ISO 40, and the noise is still quite noticeable.

hello1000, explain me why all the manufacturers use OIS on their compact cameras, expert cameras or DSLR ?

The most OIS lovers are so desperate, OIS has nothing to do with color, low light enz:

OIS is only focus on detail, the rest is irrelevant.
So stop with you bulshit Here please.

Z5p wipe the floor with all camera phones, including OIS cameraphones.

Second, the software on the camera from Z5p is still early develop.

So stop with IOS blabber please.

Sharpness while tied to OIS is not dependent on it. You need proper focus to have a sharp image, not OIS. The problem is when the camera in automatic mode and decides that the scene is too dark, so it increases the shutter time to allow in more light. Great, longer shutter time = more light, but also increases the chance it can become blurry, this is where OIS comes in and stabilizes either the sensor or lens in order to keep things in focus and maintain a sharp image.

Sure you can increase exposure by increasing the ISO but if you increase it too much, you start to have too much noise and this begin looking like crap. If you can increase the shutter time to let in more light, you will not need to increase the ISO and therefore have a cleaner image.


You can disregard what I wrote here and this link showing the iphone6 vs iphone 6 plus (with OIS)

Apart from the fact that in the photos OIS helps in maintaining clearer and brighter photos in dark scenes, can increase the shutter time and keep the image sharp, decrease ISO while at the same time using longer shutter times giving the same if not better photos than without OIS.

So does OIS work? Of course, specifically in poorly lit scenes like bars, clubs and indoors, where mind you a lot of people take photos now a days.

Will it improve in daytime photos where there is abundant amount of light? Probably not so much but I'd rather have OIS rather than not. Can it be harmful? Yes, especially in video where when panning the OIS can try to compensate and this will affect the video.

Have you looked at the photos phonoarena posted by the Z5? Did you see the photo of the Red Golf? The fact that the Sony photo looks mediocre is being fair. Sure photoarena could suck at taking photos, but somehow the G4 and S6 photos look much better.

The problem lies in the fact the samsung and LG phones can keep their shutter speed open for much longer due to the OIS and thus letting in more light, leading to better details and colour since well more light.

Z5: 5520x4140, F2 1/125s, ISO 200
S6: 5312x2998, F1.9, 1/33s, ISO 100
G4: 5312x2998, F1.8, 1/30S, ISO 100

See both the LG and Samsung can have a longer shutter speed (0.03s vs 0.008s, around 3.75x longer) letting in more light and reduces the need to increase ISO which the Z5 had to do since the scene was too dark. Sure the Sony could have done this as well, the Z5 is quite capable at 1/32s shutter time but it didn't for some reason. The main reason the LG and samsung can increase the shutter time is because they have OIS and can reduce the blur at longer exposure times.

And no the software on the Z5 family is not in early development, it should be in the final stages of development with commercial sale in October for Z5 and Z5C, and November for Z5P. Early development would have been long ago.


btw, from my earlier post on page 2 regarding the closed loop actuator,
http://www.engadget.com/www.e[....]remium-compact-hands-on-video/

It seems this closed loop system is not for stabilization, but for focus from what I can gather in this pdf, so it probably means we have no OIS but only faster focus speed.

Edit, did a test shot on my Z3, tried to take a photo without image stabilization and one with, seems when you turn ON the image stabilization the ISO automatically turns to auto and can't be changed.

On September 3, the Xperia Z5 line of phones was listed on Sony’s U.K. online store: 549 pounds (about $833) for the Z5 Compact, 599 pounds (about $909) for the Z5, and 699 pounds (about $1,060) for the Z5 Premium. The next day, those prices were knocked down to 429 pounds (about $651) for the Z5 Compact, 549 pounds (about $833) for the Z5, and 629 pounds (about $954) for the Z5 Premium, as observed by uSwitch.com.
