Chris Gampat The Phoblographer Zeiss Rokinon Sigma 85mm f1.4 three way comparison (1 of 3)ISO 4001-125 sec at f - 3.5

With Zeiss’s new 85mm f1.4 Otus reviewed, we took it upon ourselves to do an informal comparison of two of its biggest and closest competitors: the Rokinon 85mm f1.4 and the Sigma 85mm f1.4. Now granted, neither of these lenses are said to be targeted at the higher end photographer. But with Sigma’s offering being a couple of years old and Rokinon’s not being so old either, we decided that it would be great to see just how the three perform against one another.

Editor’s Note: Again we are saying that this is an informal comparison to see how the three stack up against one another. We’d like to remind our readers though that each offering is pretty darn solid, but if anything this is more of a measure of how the technology has progressed.

Sigma has shown commitment to odd ergonomic design in their announcement today detailing the new DP1 Quattro. To refresh, the DP2 Quattro was their first entry into this series. Sticking to Sigma tradition, the company’s DP1 has a wide angle 28mm equivalent f2.8 lens in front of the new Foveon Quattro sensor. Said lens unit houses one FLD element and two glass mold aspherical elements.

Just like the previous Quattro Foveon sensor, expect loads and loads of details to be rendered from the images. To see just how much, you can check out our review of the dp2 Quattro here.

Sigma states that the DP1 Quattro will feature better battery life, a TRUE III imaging processor, better ISO performance (they claim up to two tops of improvement), better autofocus, improved white balance, new color modes and better metering when it comes to auto exposures. .

But in addition to the camera, the company is also announcing a new LVF for the series with a diopter adjustment of -2 to +1. It magnifies the LCD screen 2.5x.

We have no word on pricing yet, but expect it to hit the stores sometime around December 2014

Kevin Lee The Phoblographer 150-600mm F5-6.3 DG OS HSM Sports Product Images 1

Photokina season must be in full swing because the gear announcements are coming in hot and fast. Today Sigma is introducing a three new zoom lenses and two new teleconverters. Starting with the big one, the lens maker is introducing two different 150-600mm f5-6.3 lenses for its Sports and Contemporary lines. The two lenses feature optical image stabilization and a water and oil-repellant coating on the front and rear elements.

Where the two lenses diverge is the Sports version is a big larger and made up of 24 elements in 16 groups whereas the Contemporary lens features 20 elements in 14 groups. Overall the optics in the Sports edition of the 150-600 f 5-6.3 are better with two “F” low dispersion elements (FLD) and three special low dispersion (SLD) glass elements. By comparison the Contemporary counterpart has just one FLD and three SLD glass elements.

Of course the Sports lens is built better with a dust and splash proof construction though out the barrel while the Contemporary version only features ruggedized mount. Speaking of mounts the two new 150-600 f 5-6.3 lenses will be available for Canon, Nikon, and Sony users. Sigma has yet to announce availability or pricing for it’s latest telephoto lenses, but read on to see Sigma’s new 18-300mm superzoom lens and more.

Chris Gampat The Phoblographer Sigma 50mm f1.4 Art Lens Review images (1 of 13)ISO 4001-800 sec at f - 3.5

When it comes to getting a first prime lens, many of us on the staff reached for the 50mm f1.8–otherwise known as the nifty 50. But as time progressed, almost the entire staff also moved onto the 35mm field of view. In fact, many of my personal friends have too because 35mm lenses could arguably be stated to have a field of view of what you actually see in a scene. But this is one of the biggest debates for prime lens owners: 35mm or 50mm. In a recent video, DigitalRev tried to solve this debate. Kai makes some great points stating that one is a great travel lens and street photography lens and great for working with tight spaces, but when it comes to getting bokeh you’ll want to go for the other (obviously the 50mm).

And just in case you’re curious, you should check out our Sigma 35mm vs 50mm Art comparison. The video on choosing a 35mm or a 50mm lens is after the jump.

When it comes to choosing an interchangeable lens camera and a system, consider the fact that you’re not really just buying a camera per se. Indeed, what you’re actually doing is buying into a membership club of some sort. And with that club you get the ability to do certain things. The camera will give you some features and the basic ability to take images to begin with. But then you’ll need to pair it with things that will help you to get the images you want. With that said, it’s about the lenses. And to get even better images, you’ll need lighting. Now consider this: your newer lenses will always make an older sensor look better, but a new sensor may not necessarily make older lenses deliver an image that looks better. Additionally, older lenses may not make the output from a new sensor look better.

But one thing is guaranteed: no matter how old the sensor and lens are, adding artificial lighting to your scene will make the output sharper and perhaps even look better when used correctly.

Chris Gampat the Phoblographer Sigma vs Rokinon 35mm f1.4 comparison lead image (1 of 1)ISO 4001-50 sec at f - 2.8

Rokinon recently announced their AF chipped version of their 35mm f1.4 lens for Canon EF mount cameras. For this segment of the market, it’s about time. The new lens doesn’t sport an aperture ring and instead works perfectly with Canon’s DSLRs in a way very much like Zeiss does.

With the new chipped version of the lens, we decided to see how it holds up against the Sigma 35mm f1.4–the current king of the 35mm lenses in our book.

Editor’s Note: we’re not sanctioning this test to be the end all be all of all tests. It’s informal as per the way that the site’s philosophy works with our in the field real world reviews do.
