In advance of the Photography Life’s full review on the Sigma Sport 150-600mm f/5-6.3 DG OS HSM/S superzoom, I thought readers may like to see a few sample images along with some initial thoughts about shooting with this lens hand-held. Before getting into this brief article I’d like to extend a big ‘thank you’ to Photography Life reader Michael Wroblewski, who very generously let me borrow his copy of the Sigma 150-600mm Sport lens so I could do some shooting at Bird Kingdom in Niagara Falls, Ontario.
If there was a 100 MP DSLR announced tomorrow, I would pre-order it, then spend many sleepless nights waiting for it to arrive. I’d suffer nightmares where Imatest monsters would kick Zeiss Otus’s around and laugh at their feeble attempts at keeping up with my high resolution camera. It would get even worse when I put a second mortgage on my house so I could afford the new supercomputer to crunch those images. I’d pace the halls of my house, past my favorite matted and framed 24”x36” lens chart prints, while wondering if I needed a car with a bigger trunk that could carry enough CF cards for a day’s shooting.
Each year camera manufacturers are pushing the limits of sensor technology and the latest trend has been to increase sensor resolution to numbers that were considered unfathomable before. With full-frame cameras reaching 50 megapixels (MP) and medium format cameras pushing beyond 80 MP, we now know that the megapixel race won’t stop there and we will most likely be seeing cameras with even more resolution in the future. But the big question remains – how much resolution does one truly need today? Is 12 MP too little? Is 50 MP too much? While it is a subject that can be open to endless debates, I have been working on a methodology to determine the ideal megapixel range for one’s needs. In this article, I will share what I came up with and it will hopefully serve as a good guide for our readers in deciding how to address the megapixel quench. I highly recommend to read my camera resolution explained article as a pre-requisite to understand the relationship of resolution to printing, cropping, display size and to understand such terms as down-sampling in more detail.
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.
The announcement of the new 24mm f/1.4 Art lens by Sigma comes as no surprise. It is a very obvious, and a very delightful move by the lens manufacturer, and is certainly a fitting addition to the renewed lens lineup. Featuring a wide-angle focal length of 24mm and a very wide aperture of f/1.4, this lens sits comfortably next to such highly-regarded siblings as the 35mm f/1.4 and 50mm f/1.4 Art lenses. It will also directly compete against such brand lenses as the Nikkor 24mm f/1.4G and the Canon 24mm f/1.4L II, both of which are renowned for their optical performance as well as build quality. Quite the competition, then, but if previous Sigma Art lenses are anything to go by, the new tool should be remarkable.
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):
Do you remember how it used to be with brand and third-party lens manufacturers? Brand lenses were always the high-performers, in all senses of the word. Well built, reliable and great from an optical standpoint. Third-party lenses lacked somewhat in those areas (unless you count such legendary manufacturers as Zeiss), but made up for it with very low price and niche lenses you could not find anywhere else. In recent years, however, the situation has been changing and quite drastically. Tamron 24-70mm f/2.8 VC came out. Sigma 85mm f/1.4 HSM did, too. And the 35mm f/1.4 HSM. And the 18-35mm f/1.8 HSM zoom for APS-C cameras. Need I go on? All of these lenses proved to be well built and very good optically. There is no exaggeration in saying they gave some brand lenses a good beating. So if third-party lenses started doing the “brand” thing, how should Canon, Nikon and the like answer? Well, witness this – Canon has just announced a new lens. It is an ultra wide-angle zoom with focal length range of 11-24mm and maximum aperture of f/4 throughout the range. It is designed for full-frame DSLR cameras and there is nothing else quite like it on the market.
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.
The introduction of the original Olympus OM-D E-M5 turned out to be a very successful move for the Japanese manufacturer. For the first time, it wasn’t just the compact dimensions or style that could lure potential customers towards m4/3 format mirrorless cameras (even though both aspects were taken care of by the slightly older PEN camera lineup), but some very impressive functionality along with all of that. Great EVF, speed (both AF and regular operation), great sensor (given its size), tons of customizable controls and impressively rugged build with dust and weather sealing turned a fashion object into a serious tool to tempt even DSLR owners. And it was still quite handsome with an obvious nod to those compact Olympus OM cameras of old. Why wouldn’t you? The OM-D E-M5 was a success. I am pretty certain the successor – version two – will be as well. At closer inspection you will notice the OM-D E-M5 II holds the same strengths at heart, but with everything slightly improved.
I’d be hard-pressed to call Samsung an inconspicuous company. After all, whenever you talk about electronics of any sort, there is a good chance Korean giant is leading that market or has the potential to. And yet when it comes to interchangeable lens cameras Samsung is very easy to overlook. Pay attention, though, and there is a lot to be impressed with – the recent NX1 looks genuinely capable on paper (with some specifications that are simply unheard of in its class) and puts a lot of well-received, high-end cameras to shame. It is also the reason why I am not surprised by their most recent impressive announcement, the new NX500 mirrorless camera. On paper, this is yet another strong move from a manufacturer that is not really known for its digital cameras, of all things. Yet.
