![]() However, I encountered some problems with the Wi-Fi Direct mode.įirst, the connection may cause some lag to the camera’s operations and responses, including the selection of focus points and Eye AF tracking. Simply install Imaging Edge on a desktop computer or notebook, enable the Remote function and select Wi-Fi Direct on the camera, and pair the camera with the computer to perform transmission. The PC Remote function of the Alpha 7R IV includes a wireless transmission option. To overcome the limitation of cable length, some manufacturers have developed wireless transmitters, such as the WFT-E8D Wireless File Transmitter for Canon 1D X, but it costs up to NTD 150,000! While shooting pictures in a studio, professional photographers often use a cable to connect their camera to a computer, so that they can deliver pictures to their clients quickly or verify image details simultaneously. Therefore, it definitely works well at F11! In addition, similar to past test results, the decline of image quality in the centre and edges only became obvious starting at F16. On the contrary, the resolution at F11 was almost equivalent to that of F8, even in the centre or edges of the images. The sample images show that the 61 MP Sony Alpha 7R IV did not reflect a significant decline of image quality starting at an aperture of F11 as rumoured. I loaded the camera on a tripod, took pictures of still life at an aperture of F5.6-F22 respectively, and cropped images (720 × 720) for your reference. I have to admit that I am not an expert in this area and the only way to address this question is through showing you sample images shot with the camera! The lens I used was the SEL2470GM. In a previous article, many online readers asked if the image quality will be compromised as the aperture of the Alpha 7R IV is reduced to F11. Click to view the large original image.ĭoes a smaller aperture affect the performance of this 61 MP full-frame camera? Please look at the following single-shot image and 61 MP image with Pixel Shift Multi Shooting. Due to the interference of wind, the 240 MP image is of little reference value. Here, I took a 61 MP and a 240 MP with Pixel Shift Multi Shooting. On top of that, the Yin Yang Sea in the background makes it more appealing. Thanks to the good weather that day, I visited Teapot Mountain as It was very beautiful. Thus, even if the original images are viewed, it is not easy to find afterimages when the images were composited. For this 61 MP image, 4-shot pixel-shift shooting was performed, external or human interference was minimal, and the pixel count was unchanged. In this way, images are reproduced in true-to-life colour and texture with richer details. It is of great challenge to produce a clear and flawless image at 100% view!Ħ1 MP Composited Image with Pixel Shift Multi ShootingĪs I mentioned earlier, a 61 MP image generated by Pixel Shift Multi Shooting is the result of compositing 4 images with the Imaging Edge application, so that each pixel has complete RGB primary colours. This could be that the aperture was not small enough to reduce depth of field, or there may have been an error during the composition of the images with Imaging Edge. Although I tried to minimize the human impact factors as much as possible, there is still blur at the edges at 100% view. If you have clicked to view the original 240 MP image, please take a look at the following four 61 MP images, cropped from the original 240 MP image. ![]() ![]() The above time-lapse video was shot at an interval of 5 seconds and played at 120 frames per second. It took around 2 hours from preparation to the completion of shooting and packing up. In addition, I would recommend using a shutter release remote control, whether wired or wireless, or a shutter control APP to trigger the camera so to reduce any possible slightest shock. Here, I would like to remind you that if you have similar shooting needs, you would need to prepare a sturdy tripod or light boom stand, because a slight shake or vibration may affect the quality of the original images shot at 61 MP, not to mention the 240 MP composited image with Pixel Shift Multi Shooting. After choosing the composition, I started to set up the lighting and test it before it is ready to shoot. As I had no previous experience with such similar setups, it took a lot of time to choose the appropriate background colour. ![]() After returning to the company, I began to prepare for the shoot. Then, I went to another store and selected a few pieces of tableware. To take the above picture, I went to the grocery store in Dihua Street and picked some dried fruits and Chinese herbal medicine. ![]()
