Nikon D850 - Focusing

Like learning how to focus for the first time - almost



Encanto Park, Phoenix AZ
Nikon D850, Nikkor 16-35mm f/4 @ 16mm
I went out to shoot with my new Nikon D850 last weekend and wasn't terribly happy with my results.

I was hoping, okay, expecting, to be blown away with the detail and sharpness of the better sensor. I forgot to account for the ability of the photographer!

The image at right was probably the best result I got. I was using my Nikkor 16-35mm f/4/G lens at 16 mm and f/4.5. I used the autofocus in live view, focusing on the fountain on the left of the little island. I used the self timer mode with a 4 second delay on the shutter release. None of this image seems terribly sharp to me.

On Thom Hogan's site, I had read about which lenses are recommended for the D850 and this lens is semi-recommended (the exception being that an LED used in the vibration reduction circuitry can cause "fogging" of an image). I was aware that there is some discussion about the performance of lenses with the higher resolution sensor so I was worried - was I going to have to replace all of my lenses? I hoped not.

After pondering the issue over the last week, I decided to try some additional settings.

Today I enabled the electronic front curtain shutter (Custom Setting d5). I also used the full Mup release mode. In addition, I manually focused in live view with focus peaking enabled while zoomed in at 100%. Between all of those settings, this new image looks pretty good to me.

Nikon D850, Nikkor 50mm f/1.8D @ f/1.8

This was taken with my lowly Nikkor 50mm f/1.8D lens, which is NOT on the recommended list for the D850 and it still looks better than any of the shots I did the prior weekend. Woo hoo! This crop does have some sharpening applied in Lightroom, but now I can see what the rig can do even with a less than stellar lens.

Here are the full size jpegs of the above images for reference:

Wireless Remote for the D850

One thing I always did with my D610 was to use an infrared (IR) remote shutter release to trigger the shutter. The D850 doesn't have that functionality built in. The IR remote doesn't work with the D850. I've been looking for solutions and am torn about how to address the issue. For now I'll just use the Mup mode with a release delay. I really don't like having to use an attachment with a cord, and am considering the Vello FreeWave Micro Wireless Remote Shutter Release - it has a receiver that plugs in to the 10 pin connecter and doesn't need a cable flopping around.

XQD Memory Card


I have been using a new Sony XQD G series 64G memory card. It's fine and should hold around 589 images at 14 bit lossless compressed (~45 Mb per file for the files I've taken so far). The burst rate of the camera at 7 frames per secong (FPS) is pretty cool and impressed my friend Jon.

However, during my photography hiatus, SanDisk and others have come out with some new UHS-3 SD cards that are impressive for that format - they have write speeds around 250-300MB/s! They're somewhat cheaper than the XQD cards too.

However, since most of what I have shot is landscape, I really don't need to use burst mode to try and freeze a mountain or valley or tree. Consequently, my 95MB/s SD cards work just fine. Getting the XQD was not really necessary, and it also required me to get an XQD card reader.
