Tristimulus

Because SD cards are the de facto standard for photography. More to complain about? (just had a look at your prior posts)... :-D

Sony offer real time tracking, just aim the camera at the point you want in focus and half press the shutter. Then the camera stick to that focus point even when recomposing. Handy and useful - ...

That is a find well worth remembering until next time someone can not get the most out of their Sony speed demons. Good to see that the camera is working as advertised. Trouble usually occur just ...

Just general advice. At ISO640 the second gain stop is reached on all Sony cameras. Guess no astrophotographer will notice the difference between ISO640 and a lower gain step anyway. Use ...

Put the camera on a tripod. Focus manually with the focus magnifier. Use the 10 sec timer to avoid vibration. Avoid nights with severe air currents. Then Saturn should be a tiny planet with a clear ...

Sony lenses have very fast and reliable linear focus motors. When the current is on the focus unit is floating in an electromagnetic field. Turn the current off and the focus unit is dead and ...

That is the main reason why I got the A7c. That amazing sticky focus tracking feature. Works wonders and have made my A7III pretty idle. For affordable primes the new 2.8/24 G, the 2.5/40 G and the ...

+1 Got the Sony 1.8/35 before the 2.5/40 (which I would have gotten today) entered the stage. Fine lens for the money, well built and very fast and precise auto focus. Would never buy a 1.4/35 lens ...

Oh - hope they could fix the error rate and life span of photographers too. Am worrying about the consumer grade design life span. Wish I was a pro...

Topics do not die when people disagree. They die when people agree... Wonderful problem - just shows what kind of insurmountable problems upper middle class people have nowadays. :-D

Photographers are generally pretty conservative. The transition from photographic film to digital was slow. Despite the cost and slow turnaround photographic film was long seen as the future (the ...

Most likely down to reliability, cost and having something up the sleeve now that the mirrorless game has got some momentum. That seems to be the driving force behind the Sony tracking auto focus. ...

Would be interesting to se a digital camera that stores images on punch cards. Is doable but hardly practical. Just get a punch card reader (one would never bother take and download 99999 images ...

Simple - just turn off the Canon eye AF function when not wanted. If possible... Good to see that Canon has some feature that Sony does not have, and it feels especially good when it is a feature ...

The 2022 A7IV dramatically outperformed the 2017 A9 - until the alarm clock ended my sweet little dream. :-P

Seems like Canon now goes for some cheaper long glass to attract more customers. If the lens is not for you then all is fine. Seems to be quite a few out there ready for this kind of glass. What ...

:-D And how does one take photographs with a light bulb? Bulb setting?

Interesting images! Also good to see some makeshift and homemade stuff. Wonderful when we have to find solutions and make use of all kinds of stuff. Much of my astro gear is wonderful in the dark ...

Try ISO640 next time. Do not clip the background (very deep grey is ok) next time, and be a bit more gentle with the contrast (less is better). Guess your files have a lot more data than what is ...

+1 We have had more than two dozen Sony cameras in our group - from A-mount onwards. Only one faulty camera (front wheel, faulty part from a sub contractor). Have trouble breaking the old Sony ...
