Some of the Voigtlander lenses are terrific, some are merely good. Some of the Zeiss non-Otus lenses are terrific, some are merely good.

This shouldn't be a big surprise. The Japanese make a substantial fraction of the world's medical optical imaging instruments as well.

On Gay love II challenge (5 comments in total)

also, because some straight folks get their knickers in a twist if they see same-gender couples in public displays of affection - holding hands or arms around waists, kissing, the uncontroversial stuff straight people do in public. The easily offended can just skip the photos of gay PDAs.

The #1 photo is reminiscent of one from Russia (with 2 men) that won a world press association award.

On Wood winter home for birds in the Man-Made Bird Homes challenge (7 comments in total)

Eurasian Tree Sparrows, I see. Convivial creatures, they are. I am rather fond of them, they are my town's (St. Louis, MO, USA) #1 birding attraction, having been imported from Germany in the late 1800s and having settled only within 50 to 70 miles radius from St. Louis.

There's something to be said for buying a $499.00 Sigma Merrill Foveon sensor camera with fixed prime lens (color sensor, but all color info at same photosite, unlike the Bayer array) and doing B&W conversion. Sure, it's a Foveon sensor, so you can't run it at ISO6400, but at the old ASA/ISO 100-1600 range that was the B&W film standard, it works well - and the lenses are excellent too.

Adjustable torso length or multiple sizes would be nice. I am awaiting my Kickstarter copy of the women's size Loka-equivalent, Kickstarted about 6 to 8 months ago.

I am hoping that this DPQ0 lens has similar quality to the current iteration of the Zeiss 21mm Distagon design, a wonderful lens.

ozturert: Sigma DPs lose in:
- Speed (or slowness). I can live with slow AF, but writing RAW+JPEG on my DP2 Merrill took loooong time.
- Speed (or slowness) of editing RAW files. I used Sigma's software to convert all RAWs to TIFF, then edit in ACR and PS. That took ages.
- Strange blooms on bright light sources (like a sun reflection on a window, a small light source etc..)
- Horrible high ISO performance. Above ISO800, the files behave worse than a 12-year DSLR.
They win big time in:
- Incredible detail, and in DP2's case, near-perfect lens characteristics. Incredible detail from one corner to another at f5.6, same or better performance then Sigma 50mm Art. You really use one to see this, that 30mm f2.8 lens is excellent.
- Interesting color in JPEGs, and very good color accuracy in RAWs.
- Very silent leaf shutter with up to 1/2000s flash sync.
It's obvious what to improve, but I don't see the response from Sigma. They REALLY must license Faveon to Canon, Nikon, Olympus, Sony etc..

Both the DP2M and the DP3M lenses are outstanding, and the DP1M lens is quite good. The SPP converter/ editor is the rate-limiting step in landscape and close-up photography. I haven't tried Iridient RAW Developer yet, used by some Merrill-shooters (no Quattro in Iridient, likely due to the novel file structure).

I slap a Marumi achromat 5 diopter accessory lens on the DP3M, and it works quite well up to approximately 1x. Bare DP3M lens does 1:3.5 to 1:4, which is great for flowers.

Thanks for highlighting this.

Should the photos contain the bird in or around its home?

On Canon EOS 5DS R real world sample gallery posted article (482 comments in total)

Which converters are people using, and do they like the results with the specific converter? DPP? ACR? LR6? Some other? (DXO, Iridient, etc). I am still in LR4 and if I want to putz with these files, I would have to DNG them via the free-standing Adobe DNG converter, or download the latest DPP (I am still back on DPP3).

abi170845: But the system doesn't fit the new Canon 11mm Zoom L, disappointed. I hope Hitech Lucroit System or Wonderpana will release theirs.

Lee has indicated that it is working on a solution for the Canon 11-24. Personally I am working on a solution to 1. afford 2. carry around the monster lens before I worry about its filters!

On Lee releases pricing for SW150 Mk ll filter system article (37 comments in total)
In reply to:

blackcoffee17: Why the manufacturers don't use a drop-in filter system for the superwide lenses?
Yes, the lens would be a bit longer and maybe 10% heavier but
it would be possible to use small 49-50mm filters and avoid buying and carrying monsters like this Lee filter holder.

Is there a technical reason or manufacturers just don't care?

For landscapes, many users want graduated neutral density filters. Drop in filters can't be adjusted in height. Drop-in filter slots can be used for polarizing filters - the supertelephotos can use polarizers. For low density neutral density filters in gelatin, some of the lenses have rear gelatin filter slots. Anyone who has used O.D.3 ND filters realizes that working with the filters is a PITA, you have to focus first and then apply filter and shoot. So that's another use for the front filter system.

Tasty, though! I have only encountered the de-husked frozen durian.

You forgot to add the associated ownership costs of a winch and a mount that could bear the weight, say a motorized fork mount for telescopes. Not to mention any treatments for injuries sustained in attempting to mount the sucker yourself.

What a terrific shot! Did you use a lightning detecting shutter trigger?

Seriously, it is an excellent action shot. That's an ambitious and strong bird.

Give them time. I strongly suspect that the 8-16 and 11-24 adapters are on the drawing boards.

I expect that Amazon hopes to capture the tiny amount of data it doesn't already get from existing strategies. Image recognition software has become sufficiently sophisticated that it doesn't take much imagination to believe that in a few years a computer will be able to identify make, model, cosmetic condition of car, and pump ads at you.
