One of our readers was kind enough to send a link to a YouTube video from NASA’s Solar Dynamics Obervatory (SDO), which has been capturing images of the whole sun 24 hours a day for the last 5 years. After putting together image sequences into a time-lapse, NASA created a stunning video that is absolutely worth watching. If you visit NASA’s official website, you can click on the Related Media link and see many more videos and images from SDO, which are all as amazing as the below video:
Although the megapixel race has been going on since digital cameras had been invented, the last few years in particular have seen a huge increase in resolution – we have seen everything from 41 megapixel camera phones to now 50.6 megapixel full-frame DSLR cameras. It seems like we have already reached the theoretical maximum for handling noise at high ISOs with the current generation sensor technology, so the manufacturers are now focusing their efforts in packing more resolution, while keeping sensor sizes the same in order to lure more customers to upgrade to the latest and greatest. In this article, I will try to explain some basic terminology in regards to resolution and hopefully help our readers in understanding camera resolution better.
For the next 13 days, Nikon will again offer lens-only rebates as it has previously done in the past. This is pretty exciting news for many Nikon shooters that already own Nikon cameras and are only interested in buying lenses – many of our readers have been waiting for such a rebate for a while now. In addition to these lens rebates, Nikon is also simultaneously running its “Buy Together and Save” rebate program, where additional savings are provided if you buy one of the Nikon DSLRs. Let’s take a look at these savings in more detail.
Just a day after Sigma announced its 24mm f/1.4 Art lens, it has now also announced both pricing and availability of the Sigma 24mm f/1.4 Art lens. I honestly expected over $1K price for this quality of the lens, so I was a bit shocked to see that the lens will be sold at $849, which is tremendous value if you compare it to Nikon and Canon 24mm f/1.4 counterparts. Another much anticipated lens, the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary is also available for pre-order for $1,089, which is priced right around the same as the Tamron 150-600mm which we highly praised in our in-depth review. Both lenses are expected to ship around March 20, 2015.
And for those who are interested in the newly announced Nikon D810A, below you will find some sample images from the camera. Please keep in mind that aside from the last photo, all sample images were taken as composites with multiple images, then put together via special stitching software for astrophotography. That’s why EXIF data is not present in these images. As usual, you can download images to your computer to see a full-sized version.
It has only been 8 months since Nikon announced the D810 and today the company announced a very specialized camera for astrophotographers, the Nikon D810A. In essence, the D810A is pretty much identical to the existing D810 – the camera has exactly the same body build, ergonomics, sensor, etc. What has changed is the filter stack in front of the sensor, which contains a modified infrared filter that is more sensitive to super low light emitted by the stars and nebulas (specifically, the hydrogen alpha wavelength). In addition, Nikon implemented additional shutter speeds (4, 5, 8, 10, 15, 20, 30, 60, 120, 180, 240, 300, 600 and 900 seconds) to give more flexibility for astrophotography needs. While the announcement is certainly big for astrophotographers, because it is world’s first full-frame astrophotography DSLR camera, I do have a few concerns about this particular release. Having done a bit of research in astrophotography last year (my primary interest was in deep space object photography using specialized mounts and CCD sensors), I learned a little bit about the tools and what’s needed.
As you may have already noticed, we have been experimenting with advertising here at Photography Life over the weekend. After several days of trying out Google’s advertising, we decided to settle on a few locations on the website and we have now pretty much settled on showing advertising on the sidebar and the main content area of the page. While we have tried to do our best to make ads as unobtrusive as possible, our old-time readers who have been enjoying the ad-free environment for so many years might get a bit annoyed and might wonder why we had to resort to introducing advertising on this site. Unfortunately, it all has to do with our rising costs.
If you are wondering about how images look from the newly announced Canon 5DS and 5DS R DSLR cameras, below you will find the official image samples from Canon USA for both cameras. Let’s take a look at the 5DS images first (apologies for wrong orientation on vertical images – our system could not properly handle orientation on such large files):
It has been exactly three years since Nikon debuted its high resolution 36.3 MP D800 and D800E cameras in February of 2012. At the time of announcement, Nikon’s highest resolution camera was the super expensive D3X with a 24.5 MP sensor, while the similar class D700 only had a 12.1 MP sensor. So for many, going from either 12.1 MP or 24.5 MP to 36.3 MP on full frame represented a huge jump in resolution. The cameras were truly groundbreaking, thanks to their superb performance, low noise levels and stunning dynamic range. Although Nikon faced a number of issues with quality control in the beginning, particularly when it came to calibrating the autofocus system for the new high resolution cameras, the Nikon D800 / D800E took the market by storm and quickly became Nikon’s best selling professional cameras. For three long years Canon failed to offer a true high resolution competitor, while Nikon already went through another iteration of the 36 MP line with the Nikon D810 camera. This angered many Canon shooters who wanted to get a high resolution camera that offered similar performance benefits and a much wider dynamic range than what Canon had on its existing cameras. The wait is now over, because Canon has just announced record breaking super high resolution 50.6 MP Canon EOS 5DS and EOS 5DS R full-frame DSLR cameras. Canon decided not to just bring out a competitor, but hit Nikon hard with something better in terms of resolution.
Last year I had a chance to test and review the ioSafe 1513+ storage unit, which I found to be an amazing device that not only provides data protection against fire, flood and other potential disasters, but also does it with superb performance, thanks to the Synology DSM architecture. With its relatively steep price, hefty size and heavy weight, the ioSafe 1513+ might not be an ideal choice for everyday backup needs though. For smaller environments with lower storage and performance needs, ioSafe also offers a much more budget-friendly option, the ioSafe 214. I have been using the ioSafe 214 for the past 4 months for my personal and business needs and I decided to review the unit and share it with our readers, based on my overall experience so far.
