Sony A7II & 50mm f0.95 lens mayday mayday mayday

[winnie_beex]

hello 

 

two days ago I finally got the TTArtisans 50mm 0.95 lens , platinum edition

sometimes I'm thick as two short planks , sometimes I fall in a complete blackout like now

I've done the RTFM several times , I googled and googled , went to you tube , nada 

 

how do I make the camera choose the shutter speed ?

100 ISO , wide open , tried a few combinations and , the same nada 

close aperture a wee bit and the same question .

went back to Super Tak 1.4 which is my main lens , the same ; most definitely my mind is blocked 

all frames are super over exposed 

Sony A7II 

apologies for this trivial question & thank you most kindly

You put the camera in M or S mode and control the shutter and aperture manually.
You can also put it in A mode and control the aperture manually and let the camera autoexpose the shutter.

There's also the possibility that f0.95 needs a higher shutter speed than your camera can handle, so if it maxes out at 1/4000, you might need to switch to electronic shutter to achieve 1/8000.

If you set your aperture to f8, does it expose correctly?

Isn't that lens fully manual with no electronic connections to the camera? Do you see the aperture in the viewfinder? I believe that lens is 100% manual. If that is the case, the camera has no idea what the aperture setting is, so it can't set shutter. The only way to use that lens is by setting everything yourself. Metering should still work to guide your settings.

That's untrue. The camera doesn't need to know the aperture settings, it just measures light intensity hitting the sensor and - if in A-mode - determines the appropriate shutter speed to get a correct exposure. I have several dumb manual lenses and without any electronic coupling, the camera is perfectly capable to set the proper shutter speed.

This sounds like a very plausible explanation. If you see 1/4000 blinking, it means the camera can't get proper exposure because it has hit the maximum possible shutter speed.

Fair enough. I need to check, last time I used any MC/MD mount lenses everything had to be done manually.

Ok, so I tested it, same result. Had to change the shutter with the dial.

Then it hit me. 🤔

I only shoot in manual. Never tried it any other way. 

So, I flipped it to A, and it works as you say. Change the aperture and the camera changes the shutter. It also works in P. 

Mea Culpa!

apologies , different time zone and overslept 

 

cameratose , Pieter , big0bum thank you all most kindly 

true I had a blackout , but it was in conjunction with the Tech-Art Leica M to Sony autofocus adapter 

which sort of got ill , close to death , touch wood 

it's first version , but apart from drinking batteries like water in a desert worked super fine for a few years 

thank you all 

 

perhaps you have some opinions ;

since some years ago I bricked a Sony a6000 by upgrading the firmware , I left all my remaining cameras at factory setting , firmwarewise 

is there any real benefit to up this on Sony A7II ?

thanks

Sony has released some iffy firmware updates from time to time, no doubt. I've taken the tack of not updating until I see how many people scream after they do, in other words, I let someone else be the Guinea Pig. That in mind, I haven't updated either of my cameras in over a year. But...the latest updates have been out long enough now to feel comfortable that any bugs have been addressed, so I am probably going to update them both soon  😬 

I don't think Sony has released an update for the A7 II in several years, and since we don't see any complaints, it'd be low risk. However, don't do anything you're uncomfortable with.

[winnie_beex]

very wise words indeed 

as I have and use only one lens with autofocus , Sigma 56 1.4 I very much doubt that updates for firmware will be of any consequence , the rest being Leica R lenses 

and like you said , I'm doing what I feel comfortable with 

thank you most kindly
