All filters in front of the sensor are replaced with optical glass in a full spectrum conversion.

I've had very good success with LifePixel (https://www.lifepixel.com) on four mods. They use a clean room for their conversions and I've never had a problem with dust spots which is the bane of most conversions.

Clear skies!

Thank you and good seeing to you as well.

Thank you, taking it all in and feel I will make a good final decision. I have a number of Zeiss contax lenses from the 35mm days and need to find out if they can work with the A7s. That ewould save me some money.


Yes they will work with an adapter. I use a number of Zeiss lenses (from Exakta and Rollie film cameras) on my a7s and a6000. Note: they will be full manual lenses focus and f-stop just like on your film cameras. It is easy to focus Sony a7s with focus peaking. I have a friend that has a number of Contax lenses that he uses on his sony a6500.

I was originally looking at the d5600 for price and usi ng it for low light and normal. I know its not the best for low light but I am on a buget. The pictures you are showing of the mw, did you do any stacking to produce uour image?


No stacking nor panorama stitches. Minimal PP to show you the capability. I'd be happy to private message you additional photos and answer any questions you may have.

....buy a Sony A7S (not the II) .... bwa


Why not the A7Sii ?
Is that the 'StarEater' thing.
See here for a workaround for that.

For one, the Sony a7sii costs more especially on the used market. Personally I would recommend the a7sii over the a7s because of the 5-ax stabilization but you would have to turn it off for night tripod shots anyway. So I am perfectly happy settling for the a7s for its low light capability. Note that I have the a99ii (it has 5-ax stab) and the a6000 besides the a7s. But if I had only one camera I would have opted for the a7sii.

Hello, I am new to the forum and want say hello to everyone. I went to photography school back in the film days. I am now wanting to get involved with nightscape photography and maybe some astrophotography. I am looking to get a dslr and have looked at the popular brands. Nikon 5500, Canon Eos m6 and Sony. My peice cap is $1000.00. Are there any suggestions from any experienced people on what camera may be suggested? They all seem technically similar and I see mirrorless is a rend. I need sharp low light setup.
Any suggestions?

Just to adding to my other comments, some people complain about the Pentax K1 because it doesn't have the quickest action. Of you are going to use it for sports and other fast multi shooting things, you'd be better of with a quicker camera.

I own a K1 and think it's somewhere around 5 frames a sec in burst. Several complain it not 10 fps or faster. It'd be nice for faster but for my style 5 is fine.

Thank you, the Canon I mentioned is mirrorless and around $800.


If you click "quote reply" as I did here we can tell who you are addressing.

You should also need a small flashlight with a red filter.


Pardon my asking, but what's the flashlight with the red filter used for? Notably I use a small flashlight to illuminate the controls on my lens and camera when shooting in the dark, but it doesn't have a red lens. What am I missing?

Generally a small light with red filter will not cause the eye to lose night vision.

The red light preserves night vision.

Per the LifePixel website:
"Note: The Sony A7S II, A7R II, A7R III, and A9 use an IR LED as part of their electronic shutter monitor. Once these models are converted to Full Spectrum, the internal IR LED will contaminate all images shot at exposures greater than 1 second."

As for the star-eater 'problem'. I have used the A7R, A7S and A7R II for astrophotography without ever seeing the so called star-eater problem. I guess if you're a pixel peeper and really go looking for a problem, you'll find a problem; I haven't.

Clear skies!

I have been using a used Sony a7s for about a year now with a used Samyang 14mm f2.8 The Sony a7s has excellent low noise at higher ISO compared to other cameras. I would also recomend the Sigma 10-20mm. But the new guy on the block is the Laowa Zero-D 12mm f2.8 lens. It has almost no distortion.

I don't think you'd want to recommend the Sony A7S II if you wanted to have it modded to full spectrum, per the IR LED problem encountered in all the latest editions.

Me being a Nikon shooter I would suggest the Nikon d500, it is a crop sensor camera but has excellent low light capability. This camera is more than $ 1,000
It may be had at around $1,200 - $1,400 Nikon d750 can be had at $1,200 and is full frame but the d500 has a better auto focus system the mirrorless line is more expensive, those are my suggestions on the Nikon line you may find a better deal with other brands
