My One Night Stand with the Tamron 150-600mm

Squirrel Jumping

Maybe my self-esteem was dipping that day or maybe I was just feeling like seeing how the little people lived. Whatever the reason I decided I needed to humiliate myself a bit so I decided to slap a third party lens on my Ferrari, er, I mean Nikon D4s. The choice – the Tamron 150-600mm f/5-6.3 VC USD. For the last 30 years I’d never shot anything but Nikon glass – no cheap third party lens would dirty up my cameras.

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.

The Versatility of a 50mm Prime

16 New Year Fireworks

I know, I know, the 50mm again. There isn’t much more for me to add really. The attributes of this focal length have been lauded many times in many articles, including on this site. A (usually) cheap and light prime, very sharp with a fast aperture and beautiful bokeh. A useful portrait length on APS-C sensors (75mm – 80mm equivalent field of view), and on full frame it’s supposedly close to how the human eye sees (don’t know about you, but my human eyes see the almost 180 degrees stereoscopic vision they were designed for). Still, the 50mm is often claimed as a classic and an essential addition to our kit.

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:

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.

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.

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.

Keeping The DSLR Handy

3 Windermere-Jetty

I have stated in a previous article that I probably will sell all my DSLR gear eventually, so rarely does it ever get used. Virtually all my work now is done with mirrorless m4/3 (Olympus EM-5). But I must admit to being glad that I brought my DSLR along with me to a recent trip to The Lake District and Scotland. And while I used my EM-5 for virtually the entire trip, canoeing on lakes and hiking up hills with it in a small camera bag, I knew the DSLR would be more effective at capturing the night sky. I was hoping at some point the skies would be clear enough for me to capture some stars, possibly even the Milky Way, and since I had my car bringing along extra gear was not an issue.

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.
