OL: Sigma 24mm f/1.4 DG DN ART Review – Good Value

By Louis Ferreira | Published: October 5, 2024


Sigma 24mm f/1.4 DG DN Art: B&H Photo / Amazon / Adorama

Optical Limits posted its full Sigma 24mm F1.4 DG DN ART review which you can read in full here or check out the excerpt below:

..The center performance is generally excellent, but the borders/corners leave a bit to be desired at f/1.4 – and being advertised as a lens suitable for astrophotography, that’s certainly not ideal. Stopping down to f/2 improves the outer image field a bit, but it is only critically sharp from f/2.8 onward. Image distortions are low, as are lateral CAs. The vignetting is very high at f/1.4 which is to be expected, of course, so auto-correction is needed here. The quality of the bokeh is impressive… Axial CAs are noticeable at large apertures. The build quality of the lens is impressive, thanks to a tightly assembled combination of metal and durable plastic parts. Combined with a dust- and splash-resistant design, it is certainly good enough for professional use. The AF is fast and noiseless. Videographers will certainly appreciate the de-clickable aperture ring. Overall, the Sigma lens represents good value but it isn’t an obvious choice.

DIY: Sitina 1 Open Source Full-Frame Mirrorless Camera

By Louis Ferreira | Published: October 4, 2024


Zhang created an open-source full-frame E-mount mirrorless camera that you can recreate yourself using the resources found here on github. The project started as a digital back for film cameras and grew from there. The camera is built around an AMD-Xilinx Zynq 7010 system-on-chip combined with a pair of Arm Cortex-A9 CPU cores running at 667MHz with an FPGA featuring 28k logic cells. The camera has 512MB of DDR3 RAM and an Analog Devices AD9990 signal processor with an analog front-end connected to a Kodak/ON Semi KAI-11002CM color or KAI-11002M monochrome image sensor, with a 3.4″ 480×480 ISP panel on the rear for the user interface which can be controlled on the grip.

The camera is only 10.7 megapixels which can crop down to 5.6 megapixels for square APS-C images. The images are stored as losslessly compressed raw DNG files and lossy-compressed JPEG images. The rear display refreshes at 28fps for live-view mode. Anyone can build their own cameras and the software is pretty easy to understand, but the hardware could use work.
