Thanks Besar. As you can imagine the real stories are about the crazy adventures in the early days of the East African gem business. That is when many of the now famous new stones, and deposits were discovered. What is really amazing is that we are still finding new things to this day.
My first Wife is Polish, and many times her first words to me when I made it back home were "Dupa Yash". She is the Mother of my two kids, and Grandmother to three. We are still friends,(as I am with my full coven of exes), and she still calls me that with a laugh. ...Show more →
Really, I envy your trips, to Africa.
Ha, ha... I laughed. It has to be "Dupa Jasiu" hi hi Greetings for Your first Wife

Hmm, they look pretty similar to me, at @f2.8 at least... Maybe Sigma seems a bit sharper depending on the part of the image I look at, but maybe I'm biased ...
Anyways, I think there will be Sigma review on lenstip soon, as it's already there on the polish sister(mother?) site: https://www.optyczne.pl/517.1-Test_obiektywu-Test_Sigma_A_105_mm_f_2.8_DG_DN_Macro.html
Spoiler alert: it sets their new sharpness record (@f4.0) .
Overall, similar to Dustin Abbott, they say it's optically superior to FE 90 and the only negative they list is slow AF. However, in the breakdown they also note that flare/ghosting is acceptable/good for such a lens, but not perfect.

In the pictures above, I focused on the chimney (manually).
In my opinion Voigtlander wins in distance and is weaker in macro 1: 1, but only in the f /2.8 to f /4.0 range. from f5.6 upwards are very close.

A little comparison between VC 110 and Sigma 105. The weather conditions vary, but I think you can see the differences. Distance about 25m. Crop 100%.
The Sigma appear to me to have the best bokeh of the three. The Voigtländer shows clear double lining of the rightmost antenna(?) in the background on the right side.

A very detailed review with actual resolution testing. This lens continues to set new benchmarks by multiple reviewers. No need to compare to the competition and inflame brand discussions and other petty posts. I think that it is clear that this is a very high quality optic, capable of producing superb images.
This kind of performance, build quality, and feature set, at the low end of the price spectrum for me can be summed up in one word.

It's hard to judge from the F2.8 photos because the colour/contrast is so different between the two but to my eye the Sigma is resolving more detail than the VC based on the detail on the flashing just below the skylight.

The rose that didn't know winter has come
Here's a short story of mine. I have a collection of roses in my front yard, sitting snugly together in an area delimited by stone raised walls. They are a delight to watch during the summer, but our Canadian winter doesn't help them at all, and every year quite a few of them don't make it to the next spring.
For the last two weeks we had two night frost episodes and three snowfalls that abruptly wilted all the flowers, to the extent that everything looks now like a neglected cemetery with dried up, dead flowers. The buds usually freeze and die too, and none of them ever opens up.
Except one. Which actually started to open, like it never noticed that winter has come.
So here it is, the rosebud that didn't know winter has come. With a wilted rose in the background, and at f/2.8, because I can and the lens can too. And the mandatory 1:1 crop for pixel peeping pleasure. My only regret is ISO 400 as there was a slight breeze and I had to use short exposure time.

Possibly it has mutated into a new form of "Canadian Rose" capable of withstanding the cold Winters up there. Try feeding it a beer to see if my theory is correct.

Bingo! It's actually beer that we can lawfully use for watering them. Our city council is "woke" and enacted watering restrictions. Like the water we take from the river wouldn't go back to the same river... it will go to a different planet.

Wow, that's a spectaular photo! I think it's the contrast between super sharp (i.e. crop) plane of focus and the obliterated background that does it for me .
Who whould have thought a macro lens thread would also include the stories behind the photos ...

This dead flower bud that was in my back yard attracted my attention. It has a kind of gritty beauty, and I wanted to see if I could capture that in an image.
I went to f/20 with this shot in an attempt to get in all in focus without stacking. So i imagine the image is suffering from a bit of diffraction. Still I didn't get the whole flower in focus.
I used my ring light for this image. Everything manual, with exposure set to remove all ambient light in an attempt to get a black background. I fell a little short in that and will have to fix that in post some day.
The fine fuzz all over the plant is really made sharp by the flash. If I applied too much sharpening it takes on a HDR grunge kind of look that I don't like. So, only light sharpening in lightroom. The flash and resolution of the lens is enough in my opinion. Almost no other processing except cropping square, adding the border, a custom white balance, bumping up the orange and lowering the blue channels in lightroom.

It's nice to finally have a test to compare the Sigma to the Sony, on the same camera body (a7R II.) The Lenstip test posted above is probably worth looking at for those who are deciding between the two. We've had discussions around the features of both lenses, but this gives some idea of the optical qualities.
Resolution - It's always a good sign when the scale of the chart is different... Sigma 105mm Sony FE 90mm

I received my copy a couple of days ago. It's a super sharp lens even wide open and I like the bokeh as well. Just messing around the house. DSC05290 by Jose Raposo, on Flickr

Here is a little departure from shots showing how good the optics of this lens is.
There are some bushes in the back yard that flower and produce these strange shaped seed pods. Using the Sigma 105mm macro and my ring flash, I shot the pods and beans as one image, the flower as another, and then composited with some texture images I have. Just a quick fun to do little piece that I would print and frame smallish to hang or put on a table somewhere in the house.
Another example of the kind of thing I will use this lens for.

So it wasn't as clear as I would have liked it, but it hasn't been clear on a day I was able to get out and do this, so I figured this might be good enough. Late afternoon sun gives some contrast to work with. All processed through Photo Ninja, I wanted to have more control over corrections. Didn't have much time, all the shots were a little underexposed.
Notice the depth of field wraps back toward the camera more with the CV 110. I believe Fred noticed some field curvature with the CV, not sure if that's part of it.
