Shooting with Sigma 150-600 C + SD1M: a few insights after four photowalks

In the beginning I assumed that I have to stop down to f/7.1 to f/8, in order to capture images which are sharp enough. I didn’t even try to shoot wide open. But as it turned out during today’s photowalk the 150-600 Contemporary is already sharp enough at f/6.3. This allows me to use ISO100 ...

The Beauty and the Beast: Sigma DP3M vs 50mm f1.4 Art + SD1M (Part 2)

In the first part of this comparison I tested the sharpness of the two cameras, or rather of the two lenses, at a very short distance to the motif (~1.8m). Even though the 50/2.8 is an extraordinary lens, it had to bow to the “beast”. The 50mm 1.4 DG HSM Art, being much bigger, much ...

The Beauty and the Beast: Sigma DP3M vs 50mm f1.4 Art + SD1M (part 1)

Just a few minutes ago I finished developing the test photos and uploading them to Flickr, and now I am extremely happy that I am not working as an editor at DPReview or another review site. 😉 If I had to do these tests every day, I am sure the work would make me lose ...

Comparison: DP2 Merrill vs. Sigma SD1M & 30mm f/1.4 ART

I’ve already compared the DP2M to the 30mm f/1.4 EX (Part 1,Part 2) and discovered that DP’s lens is much sharper. I’ve also compared the two 30mm lenses, the EX and the new ART (Part 1,Part 2). The only thing left to do is to compare the DP2M with the new ART on the SD1M. ...

Review: Sigma 150-600mm f/5-6.3 DG HSM Contemporary lens

The Sigma 150-600mm f/5-6.3 DG HSM is my second Contemporary lens. Except for belonging to the same lens series as the 17-70mm f/2.8-4 DC Macro OS HSM which I also have, they hardly have anything in common. It is large and heavy like every other full frame compatible telephoto lens with an extremely long focal ...

More bird photos and a couple of macro shots (150-600mm C)

With over 20 degrees on Monday, to me, it didn’t feel like winter at all. I didn’t want to miss the opportunity to take some great bird shots, so I took my SD1 Merrill and the 150-600mm C on a photo session. After hours of making use of the heavy equipment, my hair and my undershirt ...

Workflow: Less noise through sharpening with the adjustment brush tool

In the past I almost always sharpened the entire image. Sometimes right in Sigma Photo Pro (SPP), sometimes also in Lightroom after I’d developed the X3Fs and exported them as 16 bit TIFFs. However, since I started taking pictures of birds with the 150-600mm Contemporary lens, I’ve been sharpening increasingly with the adjustment brush tool ...

The Sigma 150-600 C is amazingly sharp

I don’t think I’m exaggerating because as you can see in the following image and in the 100% crop below, the lens turns out amazingly sharp for a super-tele-zoom. But only if you do everything the right way.

35mm primes and standard primes are two different pairs of shoes

Only now that I’m taking photos with a Sigma 24/1.4 Art I’m beginning to understand why 35mm or 35mm equivalent lenses and standard primes are so often compared in forums. One would assume that the difference in focal length of a few millimeters hardly matters. However, taking pictures with both focal lengths feels quite different, ...

SPP vs. X3F Tools: Noise and noise reduction (part 1)

I didn’t even notice how much SPP “pimps up” the X3Fs before I started to experiment with the X3F Tools converter which doesn’t know the many particularities of Foveon sensors and the many tricks in X3F image editing. Since it is too many insights that I could gain by comparing both converters, I’ve decided to ...
