  • I was being sarcastic. And once again you take a crop from a resized 1080 x 1920 made for uploading and then try to prove something with it in a comparison. Here is a 100% crop from the original... ...
  • Yeah I got this one as a single shot tracking on an EQ mount for 60 seconds.... 12mm f/2 How it managed to record anything with an aperture smaller than the dark adapted human eye defies the laws ...
  • First rule in night photography - throw away any stupid UV or clear glass protection filters!
  • In good light they both have about the same image quality... See here
  • Really...? Equivalent to what...? If I buy a new lens for my APS-C camera, do I need to work out equivalence to FF or medium format? Hey here's an idea! What if I work out equivalence to a smaller ...
  • Boy have I got the video for you....! https://youtu.be/anDh7JEu0r8
  • I find my Fuji 16mm F1.4 still gives more coma in the extreme corners at f/2 than the Samyang at f/2. In fact I have photos of both from the same night. Samyang at f/2... Fuji 16mm at f/2... I ...
  • Nice! That's certainly looks coma free enough to me.
  • Thanks. The old stone church one in particular looks great full screen. I find myself looking at it for ages - exploring all the fine details of the background mountainside. I'm absolutely stoked ...
  • But that 12mm f/2 is a 6mm aperture... smaller than the dark adapted eye that apparently for some reason is important to Roger...??? Is everything under 7.5mm not suitable for astro nightscapes and ...
  • I don't know why you think having an aperture smaller than the iris of your eye is of any relevance? It may be relevant if you were buying a pair of binoculars. In which case a smaller aperture ...
  • Replied in ???
    Yeah generally I do. It's a 55". As I do a lot of astro nightscapes, the photos look better projected by the screen with the lights in the room down low in the evening rather than relying on ...
  • Not the best example as someone could say technically it's at its sharpest 2 to 3 stops down. A lens like the Fuji 90mm F2 would make a better example where it's at its sharpest only 1 stop down at ...
  • Did you have some kind of filter on the lens? Like a UV filter?
  • Here's some un-processed jpgs straight off the camera if it's any help to you. First one is wide open at f/2... Then at f/2.8... You can see the diffraction spikes on the moon and Jupiter from the ...
  • That's right. Simply having a post count in the tens of thousands and using bullet points doesn't make one an expert. Remember the question is why is f/ratio a constant across lenses of different ...
  • Bought myself the 55-200 last week so wanted to go on a road trip to put it through its paces... Absolutely thrilled with this lens. It's the first time I've ever owned a tele zoom that's ...
  • Replied in ???
    I did say one of the reasons didn't I. Being half the price of a A7II was another. Plenty of wide angle fast primes. Love the layout of the direct controls. It was the overall package and ...
  • Unfortunately if you go to a popular night photography spot, you are going to have to put up with other people and all sorts of inconveniences. Torch lights, car headlights, phones, camera flashes ...
  • I was having a look at some of the albums in your link and thought you were a professional photographer. You have an excellent mastery of light and editing skills.
