Daytime Long Exposures with the Z 24-200mm
27

An afternoon session of daytime Long Exposures with the Focus Photographers group and NiSi Filters at Turimetta on Sydney’s Northern Beaches

Dreams of Green

NIKON Z 7 + NIKKOR Z 24-200mm f/4-6.3 VR @ 25.5 mm, 254 sec at f/10, ISO 200

I wanted to test out my new Nikon Z 24-200mm lens for some typical seascape work with attached 100mm filter holder and filters. As well as try out some of the NiSi 100mm filters

Here I’m trying out the NiSi 15-Stop square IR ND filter (along with my CPL in my NiSi V6 Holder)

Actually 15 stops was a bit strong given the available light and I had to bump the ISO to 200 (from the camera’s native 64) so I didn’t have to deal with exposure times in the tens of minutes!

Plumbing the Depths

NIKON Z 7 + NIKKOR Z 24-200mm f/4-6.3 VR @ 63 mm, 92 sec at f/9, ISO 64

This one taken at a longer focal length (63mm) along with a NiSi 10-Stop IR ND 100mm square filter

Slow Flakes

NIKON Z 7 + NIKKOR Z 24-200mm f/4-6.3 VR @ 26 mm, 124 sec at f/13, ISO 200

The above with a NiSi 10-Stop IR ND 100mm square filter stacked with a HiTech 4-Stop grad ND (to hold down the sky)

Below is a 100% crop from towards the bottom left corner of frame. I'm unsure if you could call this a typical example or not (it is a 2 minute exposure so things like camera movement can come into play; even diffraction limiting (@ f/13) and depth of field and selection of point of focus plays it's hand here as the camera is physically pretty close to the closest foreground (which is at the extreme bottom of the frame))

100% Crop

NIKON Z 7 + NIKKOR Z 24-200mm f/4-6.3 VR @ 26 mm, 124 sec at f/13, ISO 200

My own gut feeling is that the lens is weakest along the extreme edges (top and bottom in a vertical composition like this) at the widest end of the focal range (i.e. near 24mm). From 35mm and up and all the way to 200mm it's pretty much tack sharp across the frame

Only pixel peepers are likely to notice. However for really critical landscape work I'd use the 14-30mm for that focal range and then the 24-200 for above 30mm
