STM lenses, even on a Canon body, will not focus 

when the camera is "on, but idle" ... IOW when the

meter has timed out, etc. You hafta tap the shutter 

button to restore power to the STM. STM lenses 

have "focus by wire" ... they need power. So you 

can spin the focus ring from now til doomsday on 

you dumb adapter with no result. 

  

PS  

  

If and when you do get a smart adapter, you can 

expect partial operation of your Canon lenses and 

glitches in the functions that do happen to operate. 

  

Your dumb adapter cost pocket change. Consider 

yourself forewarned before buying a smart adapter. 

IOW listen to Jaf. Don't listen to TP this time only

Another EF 50 really will focus on a dumb adapter,

but you will have no control over the aperture :-(   

   

The only lenses you can use on a dumb adapter 

are completely manual lenses such as the Mitakon 

lenses with mechanical focus and manual aperture 

operation via rings on the lens. Such lenses come 

in severl mounts including Canon EF, but if you're 

already using an FD adapter with FD lenses, your 

dumb adapter for Canon EF lenses is redundant

to your FD adapter.

This time or anytime.

 

In any case it's totally pointless to buy an A6000 to use with cheapo adapted gear. The only selling point is the Sony hybrid autofocus. Without it, the A6000 has absolute no advantage over any other camera.

 

The Sony 50/1.8 is really good and it uses hybrid af. It probably costs as much as a Canon 50/1.8 and cheapo adapter, as well.

Adapters are very useful to many users, but they 

are definitely NOT for the faint of heart or feeble  

of skills. Successful happy adapter users do not  

tend to ask questions cuz they don't need to. So,  

IOW, the answer to nearly every question asked 

about adapters is basically "NO".

There are too many people feeding the myth that adapted lenses are fine. There are a lot of compromises and incompatibilities.

 

Anyone Who buys a Sony camera should factor in the cost of native lenses. Otherwise the camera is crippled.

 

The A6000 has bad controls and features for adapted use. The sensor isn't great either, with clear banding from the on-sensor focusing.

 

Many people make good use of adapted lenses because they understand the parameters. If you don't or won't, It's a waste of time and money.

    • ISO 320 is the A7R5's second base ISO setting. You will find at ISO 320 you will get better results than even ISO 200. I normally take a set of shots at 1600, 3200 and 6400 ISO. I am taking 60 light frames and 10 dark frames. I don't do any adjustments to the files before stacking. I really need to get organised and do some bias frames now. Here is pretty much my first successful Milky Way shot from a few months ago. I was combatting a bit of ambient light and quite a lot of cloud but I'm pretty happy with this. It was shot using my Sigma 16-28 f2.8 which is better at astro than I had anticipated, at ISO 1600.

    • Thanks for the information. Since my original post, I did some "experiments" at different iso settings. Best results were obtained at iso 320, and then increasing the exposure by four stops in Lightroom. The biggest difference compared to using a higher iso was that there was detail in dark foreground areas, while at high iso the dark areas were blocked. This is consistent with articles I've read about ISO invariance.
    • I do a bit of astro photography and do a lot of research etc. on best settings to use. I have never heard of anyone using ISO bracketing! Typically, higher ISO settings such as 1600, 3200 or 6400 are used and multiple light and dark frames are stacked to reduce noise. If you are worried about noise in dark foreground areas then just use a seperate exposure for them then blend the exposures in post processing. By the way, I also have an A7R5.
