My three SIGMAs

My three SIGMAs

Sigma SD9 (2002)
Sigma SD14 (2007)
Sigma sd Quattro H (2016-17)

The Sigmas are in a class of their own with their famous three-layer X3 sensors (Foveon) which came closest to silver film.

The first generation of camera was released between 2002 and 2003 with a 3.4 MP sensor, i.e. (3x = 10 MP)

Sigma SD9 (2002)
Sigma SD10 (2003)

The long-awaited second generation finally appeared between 2007 and 2009 with a 4.6 MP sensor, i.e. (3x = 14 MP)

Sigma SD14 (2007)
Sigma SD15 (2009)

Later released the Sigma SD1 in 2010 with a 15 MP sensor or (3x = 45 MP) at the astronomical price of 9700 USD
Reissued in 2012 the Sigma SD1 Merrill with a reduced price of $2,300 USD (apparently the same camera)

In 2016-2007, two Sigma sd Quattro appeared with a new sensor.

Sigma sd Quattro (2016) APS-C
Sigma sd Quattro H (2017) APS-H

And finally the Sigma fp between 2019 and 2021
Sigma fanatics are still waiting for the release of the famous Sigma FF, which is apparently still under study!
to be continued …

My three are a DP3M, an sdQH, and an fp.

All excellent cameras in their different ways. The ideal would be an sdQH with an L mount. I'm not sure that a full frame sensor is essential.

I have always appreciated the APS-H format
one in between 😎

I agree. Once Sigma determines that a FF Foveon sensor is not technically and/or economically wise, I hope they will release an updated version of the SD, with the L mount.

Which SD, may I ask ... and updated how?

SD Quattro. I think that sensor architecture is the direction Sigma is heading. Updated sensor. Better, more up to date onboard processors. L-Mount. Better EVF.

Not having seem a Quattro in the flesh, that picture makes it look smaller than I expected. Reviews often describe it as a large camera. It looks distinctly smaller than the DSLRs.

i have one if you took off the protruding sa mount it would be quite compact. what makes it big is that plus the large sa lenses

The main body of my SDQuattro is relatively thin instead of the boxier earlier Sigma DSLRs. The SA mount sticks out in front.
The optical viewfinder protrudes in back, but is very nice to have if you hate focusing on screen as I do. But you can also do on-screen focusing. It can switch automatically back and forth.

The grip on the right (holds the battery) also protrudes farther than previous cams, but is nice for hand-gripping and carrying the camera. With the 30mm f/1.4 I bought with it, the two are much heavier than you would think. What bothers me in hot weather conditions or very bright sun is that the SDQ will often give heat warnings!

David,
Without the battery grip attached I would agree it is a smallish camera. With the PG-41 attached it is what I would call hefty. It's built like a tank and would be able for lots of hard use. I have the sd Quattro and the sd Quattro H usually with the 17-70mm f2.8-4 on the sd Q and the 24-105mm f4 on the H version.The sd Q H with the 24-105mm and the battery is large & heavy whereas the sd Q with the 17-70mm & the grip feels very neat in the hand.
Unless large prints are required I use both of them on Low res, good for the A4 prints I usually make but would be ok up to A3.
I have never had heat problems with either one but I nearly always turn them off when not actively photographing, also extends battery life.

S, it's probably cooler where you are than where I am. We already hit almost 90 F (32C) degrees in April!

Sandy,
True, 26C here would be as high as it gets usually.
