Nikon 50mm 1.2 or adapted Sony G Master?

Anyone compare an adapted 50mm 1.2 Sony GM to the Nikon native Z lens? On paper the Sony looks sharper, lighter, and shorter. Would be curious to know how accurate focus is with the Megadapt adapter on the GM to a Z8.
I recognize you didn't put price in your calculus - but the GM is ~ $2000 and the Nikon is $1900 - the native Nikon is actually cheaper.

I doubt the Sony is sharper.

I don't doubt it's lighter and shorter.
Also, even if the Sony is "sharper" that doesn't always equate to more character and better bokeh.
If I was a Sony shooter, I'd buy the Sony.

Too many question marks about adapting that lens on the Nikon body.

Either put up with the weight and length of the Nikon, or get a Sony body.
 
If it's photography of people, the 50/1.2S by miles.

If it's astro or other things, sure, you can consider the Sony...
For astro, the differences in filter stack thickness can cause corner issues. It may be worse on wide angle lenses, but this would still need to be tested before making a decision on the 50/1.2.
No issue with the 50 GM.

Good to know - looks like a winner, then! ;)
 
Yeah I've been using the Sigma 14mm and 15mm E mount on my Z8 and it isn't as good as it claims to be on a Sony body, but I was optimistic for a normal lens it would work better than ultra-wide.
 
I suspect that you won't notice a tremendous IQ difference unless you are an extreme measurabator. Both are excellent; both will give you excellent-superb results depending on your skill.
This: measurabator

You win the Internet today... thanks for the chuckle.

Btw here are 100% crops of the GM at the center, extreme edge, and extreme corners on a Z7 @ f/1.2, near infinity. I suggest clicking "original" on the gallery page after clicking through the image below.

I use the megadap etz pro with no issues except for the shadow wavelike banding, which is caused by the filter. Megadap does not respond to this. yet otherwise great, no optical problems. Sigma Art 14mm f/1.4 superb with it (astro), also the 50mm f/1.2. The 2mm adapter thickness adds no disadvantages, since the flange back distance is correct. AF speed feels good. So I can fully recommend it, been using it for 1 year now. Maybe the new viltrox adapter is better for shadows...

Really? This here suggests pretty severe problems in the corners when adapting that lens:

well they are wrong. I am an astrophotographer and the 14mm is the best wide angle I have used and seen. superb at f/1.4. Coma etc are at f/1.4 the same like with the nikon 14-24 G lens at f/4.

Could be sample variation too. My first 14mm was trash in one corner, star trails looked like they were drawn with a highlighter. Second was uniform across corners but still not amazing.

Possible, but rather unlikely, especially as it is likely to have at least comparable problems on the native filter stack when decentered.

Then the problems came from the lens, but photographylife clearly shows that the problem only occurs when adapting to the Z-mount and not natively.

The same thing happened in the review of the 14/1.8 GM, only worse, heavy Coma problems in the corners only when adapting.

So that doesn't speak for sample variation.

The problem of different filter stacks is nothing new.

With the Sony FE 14/.8 GM, the problem is even more serious when adapting to Nikon Z and such demanding scenarios as astro in the outermost peripheral areas.

https://photographylife.com/reviews/sony-fe-14mm-f-1-8-gm/2

There are also clear user reports on the Sony FE 20mm f/1.8 G when adapted to Z.

Philipreeve.net has also addressed this topic, and here too there are clear differences depending on the filter stack, not only when adapting M-mount to Sony E or Nikon Z, the main topic of the article, but also when adapting E-mount to Z-mount.

https://www.lensrentals.com/blog/2014/06/the-glass-in-the-path-sensor-stacks-and-adapted-lenses/

For me it makes more sense that the reviewers who take the trouble to make such comparisons simply look much more closely than the normal user who of course prefers to classify his expensive G-Master on his Z-body as absolutely flawless.

Especially since it is rarely as obvious as with such astro shots wide open in the outermost corner areas and this filter stack topic seems to be particularly problematic in the wide-angle/super-wide-angle range with deep rear elements.

In practice it is usually much more subtle and only becomes really obvious in corresponding torture scenarios.

The basic problem as such does exist and has now been documented several times.

It's just that few people make the effort to carry out such comparisons.

For me, the work that sites like photographylife, phillipreeve or the Lens rental blog do on the subject of filter stack problems is more convincing than a "Well they are wrong."

I can't claim credit for that one. Maybe Thom Hogan or some other Internet pundit coined the term.

I believe it was the infamous KR who first used that term, years ago.

has reading and thinking become that difficult? a lot of words. easily sources can be found from people that ARE astrophotographers with a credible background, like Nico Carver, who can confirm how good the 14mm f/1.4 lens is. I have hundreds of photos that can prove what I have said. you could have asked instead of providing speculations and prose

adapting works very well, like I said. I have hundreds of photos from dark skies that prove this at f/1.4.

what is annoying is that banding wavelike noise that can come up in shadows areas at all ISOs with the adapter. megadap had a severe power loss problem before their last software update, which solved that. I guess something was left though. an example of that banding can be seen here:

59181803b2ff45d292973066ab5fa36c.jpg

it only can occur with this adapter from megadap at all iso seetings. I checked all other possible settings from the camera menu, too. switched them off etc. what remains is it can always occur only when the adapter is used. with native lenses it is never there.

or try and test it in a shop. I test all lenses for centering error since years. even had it on a 400mm f/2.8 lens once (transport damage it was).

for example when buying the sigma art 105mm f/1,4 I tested 3 lenses, all had mild centering error. I picked the best. when doing this after sunset even some remote lights might be visible for some coma testing. when u rent a lens you may be too prone to sample variation. I often reservate a lens if I need to thoroughly look thru the test pics at the computer at home, with serial numbers written down, so then to be able to pic the best lens. sample variation can or is severe usually. I really wonder how these internet tests mostly use one lens and ignore this. their results can be considered quite useless I think. what helps is to find many reputable websites so to rule out sample varition. if one acclaimed result is the lens is excellent, I may find another one. samyang has been famous in the astro community for their sample variation. one very good lens among half a dozen or so. never war inclined to endure the resultung endeavors though to go thru this ...
