(Note the remote works with sony’s newer cameras including the a7r III and IV but not the a7r II.) And it moves the focus by an amount that takes into consideration the current focus distance and aperture. Basically the remote lets you adjust focus by hitting the +/- buttons. However, there is now a close to automatic method for focus stacking using the Sony RMT-P1BT Wireless Remote Commander which costs about $80. Although you can focus stack manually by selecting different AF points for different parts of the scene, this is problematic because you are just guessing distances and depth of field – it’s possible to get gaps in coverage depending on how you choose the points and this has happened to me before. Unfortunately, Sony does not include this functionality in it’s cameras even though it’s a frequently asked for feature. which results in a final image with sharp detail everywhere. You then stack or combine the images in post-processing with programs like Photoshop (my preference), Helicon Focus, or Zerene Stacker, etc.

The end result is a series of shots where everything from the foreground to the background is sharp in at least one image. You tell the camera the closest and furthest points you want to be sharp and it automatically takes a series of pictures gradually changing the focus distance between them. To help address this, most camera manufacturers include an automatic focusing stacking mode. This impact is extremely noticable once your sensor is in the 40 MP range or higher. You could stop down to increase the DOF but this actually doesn’t work well with high megapixel sensors as exceeding even f/8 can result in a loss of resolution due to diffraction. Even with wide angle lenses, it is hard to get enough DOF to cover the foreground to the background and have everything sharp when viewed at 100% magnification. With today’s high resolution cameras, focus stacking is pretty much a necessity to get the maximum detail out of the sensor.

Helicon focus reviews plus#
The individual exposure details plus additional information on magnification and number of photos in a focus stack are provided. For comparison I’ve provided single shots of some images processed the usual way. I also liberally adjusted tone and color in post-processing, removed some spots and dust, and worked on the background to produce more pleasing images. The resulting DNG files were processed with stronger sharpening of 50/1.5/100/60 and an additional texture enhancement of +20 to bring out the fine details in the images. Most close-up images were shot using focus shift shooting with focus step width set to 4 and focus stacked from RAW files with Helicon Focus 7.7.4 Pro.
And with all images except the close-up shots where I used focus stacking sharpening is set to 50/0.5/36/10, with no extra tone, color, or saturation adjustment. As usual I did the occasional exposure compensation in post-processing and some slight cropping on a few images. All images are RAW files developed in Lightroom 10.3/CRAW 13.3 to Adobe Color profile with the built-in lens profile compensating CA, vignetting, and distortions with no noise-reduction. The following images were taken with the Nikon Z MC 105mm f2.8 VR S lens mounted on a 45MP Nikon Z7 camera.
