Dear all.

 

I' m Pika a new member, thanks to welcome me in your forum.

 

I need an urgent advice cause i'm thinking to switch from Canon to Sony and for many reasons i have to take a decision and buy everything before  10 days 

 

Before to choose to but a Sony A 7R 2 I want you ask you if you  know the performance of the following canon lenses on a sony alpha 7R 2 using a metabones IV smart adapter ?

 

Canon EF 24-70mm f/2.8 L USM

Canon EF 35mm f/1.4L USM
Canon EF 16-35mm f/2.8 L USM II
Canon EF 70-200mm f/2.8 L USM

 

Thanks a lot.

 

Pika

Such reports are a snapshot of one moment in time. 

Firmware updates can vary from problem solving to 

problem creating, from beneficial to nightmare. You 

don't even know in advance which firmware is your 

camera body nor your adapter until you unpack the 

items. And acoarst you don't know in advance what 

the result of any particular update will bring. 

   

Your mention of a 10 day window is unsettling. The 

only semi-secure approach involves NOT parting

with the Canon outfit until all the bugs are worked

out of the new hybrid outfit. And since that is, again, 

a snapshot in time I've called it "semi-secure" since 

the only fully secure approach is to never part with 

the Canons, maintaining two systems and enjoying 

whatever functional crossovers work for you, but 

not depending soley on a hybridized outfit. 

   

You don't need to wait for hoped-for rapid replies 

about YOUR specific lenses. Acoarst any timely 

replies will have value. But of equal or greater value 

are the discussions already occurred that you can 

research within this forum. When you read those 

you will grasp the general idea, and the level of risk, 

and realize that a 10 day "do-or-die" option is not

anything you should act upon if it involves parting

with the foundations of the Canon outfit.  

   

Maybe you haven't heard, cuz you are new here, 

that Sony has serious compatibility problems with 

its own stuff, alpha E-mount to alpha E-mount, lens 

to body problems. Again you can research that in 

this forum. Add that info to the mix, then see if you 

still feel secure in relying upon a Metabones-Sony-  

Canon 3-way hybrid outfit dependent on firmware 

from 3 independent unrelated sources. 

   

Anywho, welcome to the forum ! And, just in case

you disappear 10 days later, best wishes and happy 

trails to you !

Honestly the cheaper generic low F stop zoom lenses work just fine. Yes, pros will complain about minor differences but I'd only consider getting a Canon L 2.8 70-200 if it were on sale used for a really low price.

 

The A7RII is more than powerful enough to provide better results with a Sigma zoom lens than a Canon with a Canon zoom lens.

    • Make sure camera and lens is updated to latest firmware. 
    • 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.
