Milky Way on LSD

Hello,

 

I found some darker skies near the place I live. This is a median stack of 6 images taken at ISO6400 with a Nikon 20/1.8 on a A7r2.

This is a panorama stitch of 6 Images - same settings

Thank you!

 

The Nikon 20/1.8 performs reasonably well. Handling-wise the focus ring is a little tricky. I have not yet tested the issue in detail but I feel as if it performs a little bit worse on my 60€ commlite nikon f adapter than on my very cheap no name adapter for 18€.

 

It is already a sharp lens wide open and gets even sharper stopped down. Nightskies are very demanding and wide open the corners show some but not severe aberrations. Colors are mediocre.

 

Here is a good review of this combination. Overall I would say that the 20/1.8 is a very good value option but not the ultimate uwa when paired with the A7.

Hope this helps

Had a short look again at my adapters and my commlite adapter copy really seems to introduce color fringing even at the center on the 20/1.8 my other lenses were not as prone to the bad quality of this copy so I did not notice. Better not cheap out on the adapter if you go for the Nikon.

    • Hi Pieter, Not yet. I've thought about that, to use a tripod. But I've no time to try that yet. I'll try it this weekend and let you know.  Thanks!
    • Did you try manually focussing at 135mm, camera on tripod / solid ground, delayed release? If you can get sharp pictures that way, at least you know the optics are fine.
    • I don't know how those cameras would fare as aviation cameras - either of them are far beyond my scope of purchase - but people have been taking pictures of planes and other man-made flying objects well, as long as they have been around.  Unless the aircraft is flying straight at you or flying perpendicularly away from you, the AF lagging behind the shutter should not be an issue and in almost all cases you would be shooting at infinity so internal lens movements to acquire focus should be at a minimum.  If you are expecting to crop a lot, I guess a camera with higher resolution would be better for you but that also depends on what you are going to do with the image.  If you are going to be printing large mural sized prints, higher resolution image would be better but if you are going to print at or below 11x17 or not print at all, even a cropped image from my A7II will be good enough on any consumer grade monitors on the market.  I have seen images printed from the first generation Olympus OM-D E-M5 (16MP) at 11x17 and they were excellent.
