WHEN EDITING PHOTOGRAPHS in Lightroom, Photoshop or Capture One, do you find yourself using the graduated filter (or equivalent)?

And do you find yourself using two different graduated filters from time to time, at different angles?

For instance, you might darken down the sky with the first graduated filter, then darken down the foreground next, leaving the middle of the image lighter and brighter.

You can also do this 'in-camera' with graduated neutral density filters, placing two filters into the holder, one 'upside down'. And the amount and area of darkening can be adjusted by sliding the filters up and down.

The only downside of using a filter is that its straight edge doesn't account for bumps in the landscape, like trees or mountains that break the horizontal horizon.

But what happens if you need to angle one of the graduated filters? No trouble in Photoshop or Lightroom, but what can you do when you're using filters on a camera?

Hand-holding the filters is one answer, but now NiSi has a better one!

The NiSi Switch 100mm Filter Holder allows two filters to be rotated together or independently from each other. It’s designed for photographers who need graduated ND filters positioned at different angles, plus allows them to be rotated independently and smoothly.

The NiSi Switch allows smooth 360 degrees rotation, but also has a locking screw to fix the back holder into position.

The holder has no vignetting, even with a 16mm ultra wide-angle lens on a full-frame sensor.

The NiSi Switch is compatible with existing 100mm NiSi filters and works with the 82 mm main adaptor, included in the following NiSi kits: V6/V5PRO/V5. So, if you are an existing NiSi user, you can just order the Switch as an additional filter holder to add to your kit.

Price is expected to be $159 and you can purchase directly from NiSi – https://nisifilters.com.au/product/nisi-switch-100mm-filter-holder/.

DESIGNED FOR THE snapshooter market, the diminutive X-A7 features a newly-developed 24-megapixel APS-C sensor that produces what Fujifilm calls “memory colours,” exactly as the user remembers them!

It also delivers images with lower noise, even at the top sensitivity of ISO 51,200, which is particularly useful in low light conditions. The sensor uses copper wiring to enable high-speed data readout and features about 8.5 times more phase detection pixels than the current model across the entire sensor surface, enhancing autofocus speed and accuracy. This also improves AF tracking of a moving subject and Face / Eye detecting AF performance, even in low light.

A large 3.5-inch LCD monitor on the rear provides touch-response performance equivalent to or better than that of smartphones in general, enabling easy camera operation. There's also a new “Smart Menu”, which enables intuitive operation, allows users to adjust shooting settings with ease while checking the picture's brightness, bokeh level, film simulation effect and aspect ratio on the screen.

The rear LCD monitor boasts a maximum luminous intensity of approximately 1,000 candelas for a high visibility and the “vari-angle” monitor can adjust to any position for shooting high- and low-angles, and can be rotated to shoot self-portraits.

The X-A7 reads data from all the pixels on the sensor and uses the equivalent of 6K data to produce 4K video. It is capable of recording smooth 4K/30 fps video and can record at 60 fps in full-HD and HD video modes.

The X-A7 records up to about 15 minutes of 4K video and up to about 30 minutes of full-HD and HD video continuously.

This is the first X-Series camera to feature the “Countdown Video” mode, in which users can specify the duration of video to be filmed from the options of 15 seconds, 30 seconds or 60 seconds.

The HD High-Speed Video function records HD video at up to 4x frame rate to achieve smooth video, even when replaying a fastmoving subject in slow motion.

The X-A7 weighs just 455 g with its Fujinon XC15-45mm f3.5-5.6 OIS PZ lens and provides approximately 440 frames per battery charge.

IS SONY NOW leading the DSLR/mirrorless campaign with its latest Alpha α7R IV? It may well be with a newly developed 35mm full-frame, back-illuminated CMOS image sensor with a resolution of 61-megapixels, the first of its kind.

The new sensor’s back-illuminated structure and noise reduction techniques combine to deliver extremely low noise and high sensitivity performance, ensuring maximum image quality, Sony claims. We have yet to test the camera ourselves, but suggest that new owners pay particular attention to precise focus and reducing camera shake as any minor deficiencies in camera technique will unwantedly show up in the high resolution files.

The α7R IV also boasts an impressive 15-stop dynamic range at low ISO sensitivities, resulting in smooth, natural gradations from deep shadows to highlights and maintaining excellent colour reproduction.

The camera is equipped with a 5-axis, optical in-body image stabilisation system that has been fine-tuned to support its highresolution shooting capacity, resulting in a shutter speed advantage of 5.5-stops. Additionally, the shutter unit assembly has been redesigned to reduce even the slightest vibration that could cause blur.

The α7R IV also includes Sony’s highest resolution viewfinder in any camera, a 5.76 million dot UXGA OLED Tru-finder EVF. About 1.6x the resolution of the EVF in the Alpha 7R III, this new viewfinder provides a very accurate, true-to-life depiction of the scene being framed. The display quality can be set to ‘Standard’ or ‘High’ mode, and to either 60 fps or 120 fps refresh rate to best match the subject and shooting conditions.

Additionally, the new camera features an evolved Pixel Shift Multi Shooting mode that composites up to 16 full-resolution images. In this mode, the camera precisely shifts the sensor in 1- or 0.5-pixel increments to capture 16 separate pixel-shifted images containing a total of 963.2 million pixels worth of data, which is then composited into a 240.8 million pixel (19008 x 12672 pixels) image using the “Imaging Edge” desktop application.

So, does this mean we don't need medium format anymore? Sony says it's ideal for photographing architecture, art or any other subject that doesn't move!
