Photographer Tim Kemple is no stranger to the Phoblographer. We’ve interviewed him before about his work in the great outdoors and his photography in general. But when we heard that he got to play with the new back, we were extremely curious to talk to him about it.
Not only was he able to tell us a bit more about the experience, but he was kind enough to provide crop examples of the new back against the Nikon D800.
The test lab DxOMark released their findings today on the Sigma 24-105mm f4 lens. Overall, they seem to give it a lot of praise. But where it’s really taking the championship is with the comparisons. As a former professional photographer that relied heavily on his 24-105mm f4 L IS, I can say with experience that I used to send it in for calibration a couple of times a year. Sigma’s option seems to be a killer one though.
What’s even more astonishing is the T rating. The Canon lens is rated at T5.1 while Sigma is at T4.2. That translates into a heck of a lot more light. For the unknowing, a T stop rating is the exact light transmission rating, while an F stop is only really an approximation–at least that’s the simple way of putting it. However, Canon’s Chromatic Aberration seems better controlled.
In real life, it’s still the photographer that creates the images and having a vision for the final result is key. But it can also affect your workflow, histograms, etc. It really just means a bit more brightening with Canon’s lens than you normally would on top of more sharpening.
The lens is only slightly beaten by Nikon’s version, and that could be because it was tested on a D800.
Three of the best Micro Four Thirds cameras currently out on the market all have been noted to exhibit exceptional high ISO image quality. Those three cameras are the Panasonic GH3, Olympus OMD EM5, and the Olympus EP5. Statements around the web have claimed that the cameras have the same sensor, but the firmware inside of these cameras is really what helps to determine the final image quality as well.
And in a very quick and super informal test, we decided to put the three up against one another.
If you were to try to get into the whole DSLR game today and you wanted to go super-entry level, what would you go with? Many people spring for Canon or Nikon, and both companies have some very good options. We’ve reviewed both the Canon Rebel SL1 and the Nikon D3200 extensively and have come to the point where we believe that it’s time to make a full comparison and conclusion to help you pick the right camera for you.
See for yourself folks! Canon Watch reported on the comparison of the new Sigma 18-35mm f1.8 DC HSM to a couple of primes, and shows that it basically destroys them in terms of image quality. But we decided to put it up against some other close possible competitors in the same near focal lengths. The results: it beats all other possible competition except for one Nikon lens.
The new Canon 35mm f2 IS came in for review recently and as a lover of the 35mm focal length, I wanted to see just how far Canon has come in their technological lens advancements. The new lens has IS built in: which is actually a heck of a lot more practical than you’d think if you’re an event shooter. It also remains smaller than Canon’s 35mm f1.4 L and Sigma’s 35mm f1.4 DG. They all have different prices and also have some major differentiating factors.
