Mount the lens on a camera, then put the camera on a tripod. These patterned charts are easy to find online, and they can be stuck on a wall and used to quickly evaluate a lens. SharpnessĬheck the lens sharpness using a test chart. Open up the lens’s aperture to aid inspection. So how do you find out a camera’s shutter count?
#A7RII SHUTTER COUNTER PROFESSIONAL#
Higher-count cameras may have seen professional use (and a harder life), while lower counts indicate casual consumer use. If a camera has a very high count of 100,000 or more, it’s probably best avoided, especially because this number will also give you a little insight into the owner’s use of the camera. Fewer than 10,000 shots on a camera that is 2-5 years old is very low, with the normal amount being around 30,000-50,000. When browsing, low shutter counts often indicate less heavily-used items. Cameras are rated for shutter durability, with enthusiast models often rated around the 150,000-shot mark, and professional models rated at 300,000 shots or higher. Generally, the shutter count will give you a great indication of the amount of use a camera has seen, similar to checking the mileage on a car. (The shutter count is also known as the number of shutter actuations.) The shutter count of a camera is simply the number of times the shutter has been fired in its lifetime.

#A7RII SHUTTER COUNTER FULL#
So rolling shutter on the new Sony A7RII is both good and bad. If you need a camera with good rolling shutter performance in 4K (UHD) you can either resort to the Sony A7RII Full Frame Mode or avoid this camera altogether and go with the Panasonic GH4 instead. The Sony A7s performs better, but the difference is not huge. It might come in handy when a better rolling shutter performance is needed and you have sufficient light available.Ĭomparing the Sony A7RII HD mode with that of the Sony A7s we can see that the Sony A7RII performs much better. It is the highest measured rolling shutter among all cameras we every tested.Īs we found out on Friday the Full Frame Mode is quite acceptable in terms of quality and offers a much better rolling shutter behaviour, but we also noticed that it performs badly in lowlight. However a rolling shutter of 29ms raises concerns. The phenomenon is mostly an issue when there is overly fast handheld movement or you film fast moving objects. Rolling Shutter is for many not a purchase criteria. The Canon 1DC and Sony A7s perform a little better and the Panasonic GH4 has the best values among small cinema cameras. Below you can see a chart comparing rolling shutter between several cameras:Īs you can see the Sony A7RII joins the Samsung NX1 which had the most severe rolling shutter we ever tested. In HD (Crop Mode) Rolling Shutter is minimal with 7ms, not far off the famous Arri AMIRA camera that has the lowest rolling shutter rating in our tests. In Crop Mode we measured 29ms of latency on the Sony A7RII whereas in Full Frame Mode we only measured 16ms.

The horizontal shift between the top and bottom line of pixels lets us roughly calculate the rolling shutter latency in milliseconds. It always spins at the same speed and has a scale printed on it.

We test the rolling shutter with a rotary chart. When comparing the Sony A7RII to other cameras we can see that the rolling shutter effect is quite severe in 4K (UHD) Crop Mode. On many CMOS cameras the rolling shutter effect has become a common issue, but some cameras have a stronger rolling shutter than others. The reason for this is that most sensors read out the image line by line via a buffer. The so called “rolling shutter” is a phenomenon that skews a camera image when fast moving objects are recorded or during fast pans and handheld camera movement.
