Chris Gampat The Phoblographer Rokinon 10mm f2.8 review images product photos (1 of 4)ISO 4001-80 sec at f - 4.0

When it comes to ultra wide angle lenses, Rokinon has always offered great image quality at an affordable price. They recently announced their 10mm f2.8 for APS-C DSLRs from our usage, we think that it is a pretty decent option for architectural and landscape shooters. The lens has a better build quality than previous offerings and can also deliver some spectacular images.

The Panasonic/Leica DG Summilux 15mm f1.7 lens for Micro Four Thirds was only announced very recently, but DxOMark has apparently already gotten their hands on a copy of the lens. According to the tests that the company announced today, the sharpness of this lens beats the pants off of Olympus’s 17mm f1.8 and Sigma’s 19mm f2.8 Art lens. Additionally, it shows less chromatic aberration than the Sigma lens but not the Olympus lens. Overall though, the 17mm f1.8 is scoring slightly better than Panasonic’s option.

If you haven’t purchased either lens yet, know that both of them have retroness built into their designs. The Panasonic lens has a working aperture ring while the Olympus lens has a snap back manual focus with a working depth of field scale. Street photographers would value either one, but they’d probably lean more towards the Oly.

While these tests are interesting, we don’t think that they’ll mean that much of a difference in real life shooting situations given that modern software is just so good at fixing these problems. And even if you’re a JPEG shooter, the cameras have a way of correcting any issues. Additionally, when you post the images online we highly doubt that everyone you know will try to go in and pixel peep.

Still though, this is interesting to note about how the technology is advancing. We got to try out the 15mm f1.7 and we reviewed the 17mm f1.8 a while back as well as a comparison to the 20mm f1.7. Be sure to check out both of those reviews.

Though they’re two different focal lengths, this question was bound to be asked by someone. Sigma now has two excellent options for full frame users from their Art series of lenses: their 50mm f1.4 DG HSM and their 35mm f1.4 DG HSM. Both have been tried and true to be capable performers. But which one is best for you?

Sigma recently updated their 50mm f1.4 lens to include not only the Art branding badge, but also a totally new look to the lens. The new Art offering joins the 35mm f1.4 as another prime for DSLRs under the new Global Vision that the company is touting right now. Many folks own the older Sigma 50mm f1.4, and with the release of the new one you might be wondering if it’s worth an upgrade or not.

In our real world tests, we explore the differences.

Chris Gampat The Phoblographer Sigma 50mm f1.4 Art Lens Review product lead (1 of 1)ISO 4001-100 sec at f - 3.5

Sigma’s 50mm f1.4 DG HSM Art is the successor to the company’s previous 50mm f1.4 lens that was also held in very high regard. However, the new lens has been brought in line both in terms of design and image quality with the company’s new Global Vision–and specifically under its Art lineup. The focal length and aperture are an iconic one that many photographers swear by. In fact, many only shoot with this one lens.

But is Sigma’s 50mm f1.4 DG HSM Art offering enough to make you want to trade up?

Last year, we declared it to be the year of the third party lens manufacturer–and that strength seems to be going deep into this year. Today, DxOMark released the findings on the company’s 18-200mm f3.5-6.3 DC lens that was recently updated. Now, despite the fact that the Nikon and Canon versions are both older optics, the Sigma has outperformed both–leading both companies by quite a bit. Sigma’s option for a lens that has been typically not been looked at for its sharpness is outdoing both Nikon and Canon. But the reason for this may be deeper.

If you look at the T stop transmission data, you can see that Canon and Nikon both let in more light. But the fact that the Sigma is letting in less could mean that this factor is attributing to the extra sharpness and if it were instead putting out a less number, it could only be slightly better than the two.

We have the lens in for review right now, and so far we’re finding it to be very warm and quite contrasty. The latter is a trademark of Sigma’s optics and helps to add to perceived sharpness. We will have to wait until the full review is done though to give our final judgement.

With many camera companies struggling, it seems like they’re focusing more on cameras than lenses. And with that, these third party companies may come to even greater prominence. But sales and bundles are a totally different consideration than what tests and reviews say.
