Focus problem (eyesight)

[Snowfun]

Hi,

As the eyesight deteriorates I am finding it increasingly difficult to focus (and set exposure) using the BMCC and BMPCC screens. Especially at awkward angles. I tried using glasses which are functional but are a nuisance (nor do they help with awkward viewing angles).  I'm therefore thinking of getting a SmallHD 502 with the sidefinder to help.  Anyone have any advice and/or experience on this? One alternative would be to get a VA but although that would help with viewing angle and position it doesn't have the magnified viewfinder.  I could use the VA4k with my A7s (and sell my Atomos Shogun) so the recorder would be used. I drive everything from vloks so power or battery compatability isn't an issue. 

Thanks.
