Maybe... Have the A7III but have not done much testing yet (bright nights here, but know that the star eater issue kick in for 4 sec and longer exposures - gotten around to test that). For wide ...

Vi presser druene, ikke vinen. Den er god - skål! ;-) What do you get when you press a grape? A little whine...

Have to agree - it is NOT about the whine, it is about the glass! :-D

Please let the Rho images loose - we do not tire... At my notherly latitude Antares culiminate less than 5 degrees above the southern meridian, and at culimination time we have nautical twilight ...

Guess a cheaper 24-105 will pop up, most likely having variable aperture (pure guess but price wise a variable aperture lens is more likely). Said before the 4/24-105 was released that I would get ...

Have the 18-200 LE and have gotten lots of great images back home. Until pixel peeping, that is. :-D In my case the 18-135 will soon replace the 18-200. Want to save some weight and snappier auto ...

Interesting work (always wondering what this Kasson is up to next when pondering over the latest findings)... Now - what would be really interesting is to see how the worst case actually affect ...

This image is stellar! Impressive resolution and tasteful colors - really something to like. Not possible to take an image like this one from here, as this is a low hanging object (am a northener) ...

The sky rotate 15 degrees per hour. Expose for 3 hours to get 45 degree rotation and so on... One hour will show circular star trails but in my opinion the stars should travel a bit more to give a ...

For the prehistory check out Fraunhofer (first to explore optical glass properties and first to compute lenses, among lots of other things) and Guinand (first to successfully produce homogeneous ...

Zeiss do not make optical glass. Schott does. Zeiss own Schott AG, but this is still two different firms. Even LZOS in Russia have been a sub contractor to Zeiss, as well as several other firms ...

Well, I have never called the Tamron mediocre (that was someone else). I have also never called it stellar... Actually I use less than optimum lenses daily and and am happy with that. Image content ...

The corners seems to be a bit soft at full aperture and the vignetting is quite strong. Center sharpness is very good. The lens is really fine at f/8 - f/11. That is good, but stellar? We are ...

Remember the days of color slide film when pitch black was pitch black ... and the duplicates were even darker. Love digital days! :-D

This lens seems to perform as expected given the aperture, size and prize. The lens seem to be far from mediocre, but also not shining like a GM lens. Quite as expected. Seems like my much bashed ...

What is pure Zeiss? Zeiss have had outsourcing from day one (Schott glass factory)... What has stayed constant is focus on premium quality based on premium design, premium raw materials and premium ...

The lower resolution when reviewing images is also observed here - so that seems to be how real life is. ;-) Does not bother me the least - the finder and the rear screen are just that, finders. ...

That is how the camera is supposed to work - to guesstimate (no random guessing here) an average exposure without too much clipping or lost shadow. Use face detect and the camera will expose for ...

Would use a wide aperture and more focus steps if isolating the background is important. Would use about f/8 and less steps if lazyness set in... Best thing: test exposures as you already know your ...

The Sky&Telescope homepage might be a good start, there is also stuff for beginners...
