Nikon Confirms the D810 Thermal Issue and Offers a Solution

Nikon D810

As you may already know, we recently reported the thermal issue with the Nikon D810 when using long shutter speeds and we immediately reported the issue to Nikon, as soon as we confirmed that all camera samples we’ve handled so far had the same problem. Since opening a trouble ticket with Nikon, we have received communication from Nikon USA that Nikon engineers were investigating our image samples and that a follow-up with details would be provided, once available. Looks like Nikon USA has officially confirmed this issue today (here is the original advisory published earlier at Nikon Japan). There are good news – Nikon has issued a service advisory, so every Nikon D810 owner will be able to get it repaired. Nikon will implement a firmware update and adjust the camera sensor to take care of the problem.

Is Nikon D810 Sharper than D800E?

Nikon D810 vs D800 / D800E

As you may already know, the difference between the Nikon D800E and D800 is their filter stacks – the D800E has the same size stack as the D800, but its third filter reverses the effect of the first one, essentially cancelling out the effect of the optical low pass filter. This is clearly illustrated in the below image, which compares the two filter stacks side by side:

Moon – Waning Gibbous

Waning Gibbous Moon

Just wanted to share this photo of the Waning Gibbous Moon with our readers, captured with the Nikon D810 and John “Verm” Sherman’s amazing Nikkor 800mm f/5.6E VR monster coupled with the TC-17E II teleconverter. I have not been able to get this much detail from such long focal lengths before, because the shutter vibration on previous generation Nikon DSLRs would shake the camera too much at the beginning of the exposure. We set everything up on a sturdy tripod, then rest the front of the lens on car’s hood, with a soft pillow in between to dampen the crazy vibrations occuring at 1350mm focal length. Set the camera to Manual mode, ISO 800, 1/250s @ f/11, then used camera’s Live View to acquire perfect focus on the moon. With the “Electronic front-curtain shutter” turned ON, we set the camera to Mirror Lock-Up mode, set “Exposure delay mode” to 3 seconds for additional protection, then fired away. Here is the result:

Nikon D810 and Sigma 50mm f/1.4 Art Performance

Nikon D810 and Sigma 50mm f1 (2)

Some of our readers have been asking about the performance of the Sigma 50mm f/1.4 Art lens on the Nikon D810, particularly about its autofocus speed and accuracy, especially in low light situations. Lola and I recently shot a wedding with this combo and I had a chance to test out the lens in various conditions – from broad daylight to very dim indoor environments. In this article, I want to talk about my experience with the lens and talk about its pros and cons when using it with the Nikon D810.

Profoto TTL-N for Nikon Announcement

Profoto Air Remote TTL-N

As you saw from our review of the Profoto B1, we were very impressed by the capabilities of this portable, battery powered flash head. At the time we wrote the review, the Profoto B1 was only compatible with Canon TTL and support for Nikon TTL was supposed to be announced later. Well, the wait is almost over, because Profoto announced the Air Remote TTL-N for Nikon, with expected availability on September 15, 2014.

Nikon D810 Thermal Noise Issue

Nikon D810 Thermal Noise Issue

While working hard on reviewing the Nikon D810 DSLR, we are doing our best to continue providing detailed coverage about the camera and its capabilities to our readers. Although we have been very happy with the improvements we see on the D810 (which does deserve high praises for its overall performance), we have identified one issue that probably needs Nikon’s attention sooner than later – the D810 seems to have a thermal noise issue when shooting very long exposures. In certain conditions, the camera seems to be produce very fine grain at low ISOs (even base ISO) that should not be there. Although most photographers probably will not notice it, those that photograph the night sky, architecture, waterfalls and seashores at exposures longer than 20 seconds surely will. The grain appears to be of different color and spread, which means that what we see in images are essentially hot pixels. Please note that these hot pixels are not of the same permanent kind discussed in this article – these hot pixels appear as a result of heat and they appear in different locations of the frame. Although such “thermal” pixels are very common in digital camera sensors and are supposed to show up when shooting long exposures, camera manufacturers usually clean them up, whether you shoot in RAW or JPEG format. This clean up happens in the image processing pipeline, before RAW and JPEG files are generated.

Sensor Gel Stick for Sony is available in limited stock

Sensor Gel Stick for Sony

Just wanted to let our readers know that the Sensor Gel Stick for Sony cameras is now available in limited stock. We have already shipped our first batch of pre-orders and now we are ready to accept more orders. We apologize for being a bit late on delivering the product – the manufacturer had some unexpected delays and could not ship the goods our way on time. We are almost out of the regular version of the Sensor Gel Stick as well, hoping to get a new batch within the next 2 weeks. So if you need to clean your sensor, we would recommend to do it sooner than later before the stock completely runs out again.

Sigma 50mm f/1.4 Art Sharpness and Bokeh Comparison

Sigma 50mm f/1.4 Art

While initially testing the Sigma 50mm f/1.4 Art lens for our in-depth review, we only had access to the Canon version of the lens (since it came out first), so we could not provide comparison results to other similar focal length Nikon prime lenses. Thanks to our friends at B&H Photo Video, we recently received two copies of the lens for the Nikon F mount to finally complete the review. We also obtained the older version of the lens, the Sigma 50mm f/1.4 EX DG HSM, along with the Nikon 50mm f/1.4G and Nikon 58mm f/1.4G lenses for comparisons. Unfortunately, the Zeiss Otus 55mm f/1.4 we tested was not available at the time and we could not include it in the below bokeh comparisons, although our usual sharpness tests were carried out and those are included in this article.

Nikon D810 for Bird Photography

Nikon D810 Bird Photography (2)

We are continuing our coverage of the Nikon D810 and today we want to talk about the capability of the D810 to photograph wildlife, particularly birds. Bird photography is complex and very demanding in terms of gear when it comes to autofocus speed, accuracy and response time. While mirrorless cameras have become a superb choice for everyday photography, they are hard and sometimes impossible to use for photographing fast-moving subjects, like birds in flight. Most mirrorless systems today don’t even have fast telephoto lenses longer than 300mm. Hence, DSLR cameras are the default choice for wildlife photography today.
