Sigma is teasing something to come on 07.07.2026. Looking at the red, blue, green colored images, it strongly hints Foveon. What do you all think?

I have a big feeling that it exasperated due to Florida’s crazy heat 85-90 w/humidity…but anyone have any fixes?

Currently seems like I could easily pull it off, if necessary.

In case you haven't come across it yet, over the past few years I have been curating LEICAmount.com (no official endorsement by Leica Camera AG), a searchable database of Leica M Mount, L Mount and S Mount lenses in production.

The crown jewel of this database is the list of 220+ Leica L mount and 180+ Leica M mount lenses from various manufacturers, that can be searched and filtered by specifications; such as mount type, focal length or aperture.

I've been using the database myself for looking up lenses for my Leica M2, so I am confident that you can make it your regular place for comparing and selecting lenses.

The next integration for this Autumn will be adding LTM lenses currently in production. But feel free to drop me a line if you spot any error, or see any lens in production missing from this database.

I was thinking of sending my a7i to get it thin sensor modded to use my ms optic lenses. Decided to just get the sigma bf instead and am loving how it looks, feels, and the significant jump in image quality at the corners.

I recently got the Sigma 65mm F2 and went on a little photo walk around Berlin. All images are shot widen open and sooc with the Foveon Yellow profile.

The lens is incredibly sharp, with good contrast. So far I really like it as a versatile companion to the 35mm F2.

Hi all, as most of my photos tend to be holiday stuff that includes landscapes and foliage, I've continued trying to find a sweet spot for clouds especially the green - yellow shift and some warmth in white balance.

Here's an image where I've done 4 versions - standard profile and auto white balance, t709 auto white balance, t709 "daylight" white balance, and t709 +1 look effect and daylight white balance.

Personally I think the latter gets the best colours... 709 fixes the greens but in city shots does tend to warm buildings etc. I've noticed auto white balance in sunlight leaves some warming, but switching to daylight setting fixes this.... Though I assume that will be less successful when not in daylight sunlight when taking the photo!

Also one thing I found is standard with look effect -5 seems identical to 709 base, but as you go + on 709 or go to standard -3 or 0 etc standard moves the greens yellow while 709 holds them green but adds punch / saturation.

Interested what others think and have found... I'm really trying to find a "standard" setting where most images come out ok on jpeg, then I edit a few dngs where required... Whereas I've been finding anything with foliage needs a bunch of editing so far (so am planning to try 709 and auto white balance or 709+1 look and daylight as a default).
