Sony A7/(r) image sharing thread

Work comes first. I have been waiting for blue skies since Nov.

Lens too big and heavy. Fortunately, body is small and light. Surprisingly, the entire package is manageable. Auto aperture, manual focus. Since is UWA, is mostly at infinity.

More pictures. .... grey sky very discouraging to shoot...
 


Doesn't look that small. Seeing this, I am thinking maybe Sony find it difficult to keep the size of these FE lenses small enough. 35mm f2.8. Instead of 50mm f1.4, they went f1.8 and longer at 55mm. I suspect instead of 85, they may do a 90mm or even 100mm f2.8. Speculating just so you don't have too high expectations.
 

Nope, definitely not small for a f1.8 lens. The actual size is 2 times the length of the 35FE.

I guess this is the sacrifice in terms of size of lens to meet the requirement of having a FF camera that is so small and thin.

The 50lux is a F1.4 lens, yet so small as compared to this F1.8 lens. But it comes with a huge cost difference of course.

I think (and I'm no optic expert) the direction for Zeiss is to create a lens with prioritisation to IQ rather than size. Look at the Otus as compared to a 50Lux.

Leica otoh will need to design their M lenses compact for their rangefinders, small, fast and well corrected with money no object set of priorities. Two different sets of directions I guessed?
 

The difference is because the zeiss 55 1.8 is designed as a slr lens design while the 50 lux is a rangefinder design. The closer mfd of the 55 1.8 explains te longer length of the lens for the focusing to be possible vs the 50 lux.

the zm lenses designed for rangefinders are equally small as the leica lenses.

This is exactly what I am thinking too. :D

I don't think they will have issues with longer focal lengths though.
Those lenses seldom have edge issues (though the same can be said of fast 50mms.... :think: )

The lenses are larger to maintain the high IQ even to the edges.
Its basically projecting a large image circle to be 'cropped' by 135 format.
The same can be said of recent Sigma lenses.

I have not tested much this lens on my A7r seldom going out now to do street candid....

Leica Elmarit 135 on A7r wide open I think was really far from my subject for this shot :-) good thing peaking is spot on majority specially F2.0 and above

Did a quick comparison none scientific one just basic one

Testing both of my Wide lenses. Both are F11 and ISO100 and focus to Infinity

1. Canon FL 19mm F3.5 R @ F11 ISO100

2. Leica-R 21mm F4 Super Angulon @ F11 and ISO100

Both seems to hand color nicely I like both lenses only issue I have with Canon is the vignette I am suspecting it's the adaptor as it seem heavy on the right upper side than the left upper corner. The Leica has vignette also but not as heavy as Canon. But both can still be corrected

What do you think guys?

Not small, but quite light. Balance is good. Here's a pic of the A7r with the Pentax DA40, which is a full frame lens.

Hi bro thanks yeah the lens seems to perform well and noticed very less barrel distortion the imagine posted are not been corrected just crop a bit to remove the vignette. Yeah it's big bigger than my Leica-R 21mm Super Angulon :-) yes the lens could take filter (77mm) one thing I like with it also. Sadly my FL-NEX adaptor upon visual checking seems the one causing the Vignette than the lens.

My lens although has a marking it say "R" but it looks like the FL non-R version :-(

Thanks for the info.
Looks like another viable option for a UWA.
 

FE 55/1.8...











Happy CNY bros... Huat Ah!!!
