The Ultimate Lightweight Camera for Night Photography

Weight is the enemy of every hiker and backpacker. I spend my days hiking to remote locations in the mountains and desert. The weight of my gear is always a burden even though I have minimized what I carry. When Sony announced the a7R and a7, I was excited beyond belief. It sounded like the answer to all my prayers! Then Nikon came out with the Df, yet another lightweight option! What to do? I put them to the test, side-by-side, of course.

Night Photography Cameras Compared

To compare these results with other Nikons, take a look at my previous post where I test out the best Nikon for night photography. Keep in mind the Df has the same sensor as the D4. The Nikon D610 is another good lightweight choice, and you can see why in this post.

I have been shooting with the Canon 6D with great success and highly recommend it for night photography. I included it in this test as a baseline since I consider it to be one of the best on the market, plus it is relatively lightweight for a DSLR.

All images were taken with the same lens, a Nikon 14-24 f/2.8. A Novoflex adapter was used on the 6D. The Novoflex and a Fotodiox adapter were used on the Sonys. This test isn’t about sharpness, it is primarily about high ISO noise performance. All shots were taken at ISO 6400, f/2.8, for 30 seconds.

Weight Considerations in Night Sky Photography

This is what got me excited about the Sonys in the first place. I wanted an ultra lightweight camera with a full frame sensor for hiking and backpacking. The a7R sounded like a dream come true. It is very light, no doubt about that.

a7/a7R – .8975 lb
Df – 1.56 lb
6D – 1.6975 lb

Although not included in this test, for reference the Nikon D610 is 1.67 lb

Night Photography Controls and Adaptability 

In night photography, ease of use is extremely important to minimize how many times you turn on your light to maintain night vision. I consider myself to be very adaptable to different systems; I have shot with Nikon in the past for many years and I am currently shooting Canon. I also spent nearly a month shooting with the Sony a7 to become comfortable with it. I can usually switch brands without too much brain damage but with these bodies many frustrations came to the surface.

6D – This is your typical DSLR. It functions normally and very easy to use at night.

a7/a7R – I cannot tell you enough how much I struggled with the a7. The buttons were not intuitive and seemed to change in different modes. Figuring out how to zoom in during live view (and keep it zoomed in) was painful. I had to assign custom buttons and change settings. My frustration ran deep with these cameras. I really wanted to love these cameras. I tried and tried but they never became intuitive.

Df – Most of the functions of the Df are typical of other Nikon DSLRs and it is very intuitive to use. The big exception to this are the retro dials used to change the ISO and shutter speed. I thought these would be cool to operate until actually I had to. First off, you have to hold down a tiny lock button while you rotate the dial, which is incredibly cumbersome. I have skinny fingers and it was not a joy to use and if you have fat fingers then don’t bother. At night you cannot see what you’re changing the dial to so a light is necessary to change these settings.

Focusing for Night Photography

My go-to method of focusing is using Live View to zoom into a bright star in the sky and manually adjusting until the star is a sharp point of light. As you will notice below, the a7/a7R images tend to be out of focus. This was due to the poor performance of Live View. The stars were not as bright to me on the screen and you couldn’t zoom in as closely. This is a major downfall for night photography. The 6D and Df work flawlessly in this regard. I’ll give a slight nod to the Df with its ability to zoom in a bit further than the Sony (and this is typical of all Nikons with Live View).

Mirrorless Cameras for Night Photography

Mirrorless technology has come a long way. The electronic viewfinder of the a7/a7R is quite stunning during the day and is quite usable. This all changes at night, though. At night, I look through the viewfinder to frame my composition. Although there is very little light coming through in my shooting environment, it is typically enough for a DSLR that has a pentaprism. Looking through the viewfinder of the Sony is simply seeing a black screen – nothing there whatsoever! When shooting, I had to guess at my composition, take a test shot and guess again. This was a painful deal breaker for the a7/a7R. The Df still has a pentaprism, it is not mirrorless, so this is not a problem.

Cameras Compared: High ISO Performance 

Night photography requires extremely high ISOs. I have found the best ISO to use in general is 6400. This gives you a good exposure with relatively low noise.

I opened a file from each camera in Photoshop, zoomed to the same area and took a screenshot. These files are straight out of the camera with no noise reduction applied.


They all seem to perform similarly with an edge going to the Df for color noise.

Next I removed the color noise in Lightroom – no other adjustments were applied. This helps to see the Luminance noise, which is our main concern.

Now you can see the Df handles Luminance noise the best, followed closely by the 6D. Surprisingly the a7R performed very well and is close to the 6D. The a7, on the other hand, I was not impressed with at all. This was quite the shock considering the a7 has 24 megapixels vs. the a7R, which has 36.

Cameras Compared: Color Rendition 

I found the 6D to have the worst color rendition among these cameras, with significantly less color being recorded in the foreground and the clouds. A boost to the saturation helps some of this come back but when the color isn’t recorded well in the first place, it’s hard to bring it back. It’s not so bad that I wouldn’t recommend the 6D though.


Overall, I believe the Df reproduces color the best. The a7R was very close but did display significant noise in the shadows when pushed. The a7 did not perform well in comparison.

The Canon 6D is by far the best value. It performs incredibly well at night. The only advantage the other cameras have over it are weight and color rendition.

For ultimate quality, I’d go with the Nikon Df. It has the same sensor as the D4, which is double the price. This is a camera I would highly recommend renting before purchasing, though. It’s a bit of an oddball with its retro design, which many people do not like. With the exception of the dials, I found it enjoyable to use.

a7R – If you want the lightest full frame possible, this is your camera – especially if you primarily shoot landscapes during the day. If you only shoot at night occasionally then this camera is usable, just with a bit of frustration when composing.

a7 – There is no reason to buy this. Sony crippled it. It should have performed better than the a7R at night but it’s not even close. Tsk tsk, Sony.

On a side note: the Nikon D610 is also a great contender in this field of lightweight cameras. When price is taken into consideration it is the best value in Nikon’s lineup for night photography and only slightly heavier than the Df. If you’re shooting when the sun goes down, make sure to check out our guide on the best low light cameras to get the most out of your shots!

    Would love to see the A7S and A7RII thrown into this test. I’m guessing for this testing the A7S would perform very well.

    Sony’s AR7II is coming. Could you make a similar comparison between Nikon D750 and Sony A7RII? It would be very helpful. I am interested in night photography of landscapes.

    Thank you for the great info! For 8 years, I’ve only purchased the Canon Rebel. I’m ready for a camera with more depth and ability. Although, the price tags keep me contemplating what I should do. Thank you again! ~Tammy. 🙂
