Comparing a Nikon Df to a Pentax K3 is a little like comparing an apple to an orange, but that’s the point of this post; neither is a *better* camera, each being better at certain things. This isn’t a laboratory controlled pixel peeping review, but simply observations when using my cameras in real life.
I’ve been shooting Pentax for over 30 years, so I instinctively move along with Pentax as their product line evolves, so adding a Nikon body to my bag is a big change (and added expense!). I should mention that I have no intention of leaving Pentax. I still think it’s the best choice for everyday photography along with telephoto work. So why the Nikon? Half of what I shoot is in low light, so there is definitely an allure from having the high ISO performance that full frame offers. Why the Df? I’ve spent decades shooting film, so a film style body packed with the D4 sensor is a natural attraction. The Df currently holds the title of offering the best high ISO performance on the market.
There are also a couple of lenses I have wanted to own and either can’t find them, or they simply are not available for Pentax. I have started off with ordering the Df with its special edition 50/1.8, the Zeiss Apo Sonnar T* 135mm F/2.0 ZF.2 and the Zeiss Distagon 21mm F/2.8 ZF.2. I’ll need to take time to compare landscape work between the 21 and a similar focal length on Pentax, but based on what I am seeing so far, the 21/2.8 would be better matched with the K3.
I took both cameras to Butchart gardens at night with the intent of testing high ISO performance. A quick comment regarding the K5 vs. K3, I’ve taken a number of shots and the K3 seems as good to my eye. All Pentax shots are uing the FA 77 and the Nikon is using the 135. Anyways, I started at ISO 3200;
The K3 is first up. All shots are using the FA77.
Now the Df….using the Zeiss 135.
As expected, there is noticeably more noise with the K3. Both do well in detail (the scratch shown in the star on the centre left is blocked by a twig on the Pentax).
I did have some trouble nailing some shots with the Nikon, either through use error, or what I am assuming is the benefit of shake reduction (obviously not available with the Zeiss on the Nikon). The red tree trunk is a reflection off of the pond. This shot is with the Pentax @ISO3200. I was not successful getting a shot with the Nikon…
Both of these shots are at ISO 3200. The first shot is from the K3 with the second being the Nikon.
At ISO 12,800, as expected, the Nikon shines but the K3 holds its own;
Here is the K3….
And the Df….
Here is a 100% crop of the K3…..
and the Df……
Finally for ISO, here are two more shots at 12,800;
First the K3….
and the Df…..
So what about shooting in good light? First the K3 at ISO 100;
Then the Df at ISO 100
Another set with the first being the K3…
and then the Df….
100% crop from the K3…
100% crop from the Df….
Summary;
Personal preference and shooting style plays a big factor in choosing a camera. For example, I haven’t used both cameras in a studio setting, so if that’s where you spend most of your time, then you might (or might not) rate the cameras differently.
From first impressions with the Df, if I was to choose just one camera body, the K3 would be it. I’m looking forward to many years of use of the Df and can see it helping with half of what I shoot. I would be curious to compare it against the D800e, but already chose the Df over size and the way I like to use the camera. The Df has amazingly clean high ISO shots.
The K3 will continue be my go to camera for day to day shooting. Besides the cost factor, the build quality and form factor is better. The shell construction is much more solid, being all metal vs. the metal/plastic shell of the Df. The K3 offers in body stabilization and includes video which are not available on the Df. When I made the decision to pick up the Df, I had made the decision to stick with APS-C Pentax for Telephoto work, but I was a bit surprised at the performance of the K3 at lower ISO. As such, the K3 will see more use than I had originally thought.
K3 Pros
- Cost
- Build quality – metal vs. metal/plastic shell construction
- IQ at low ISO
- APS-C Crop for telephoto work
- In Body Image Stabilization
- Video
Df Pros
- IQ at high ISO
- Availability of aftermarket lenses (Zeiss / Voigtlander)
