I have an old stock Vixen Foresta ZR 8x32 WP which was my favourite, so I got the Sherman Pro 8x42 which looks like it except for the larger barrels and objectives, to see if it might be even better. The two brands do indeed appear very similar but on a closer look the parts are different. On the Sherman 8x42 the eyepiece glass has a greenish hue and is 2.5mm in diameter, while the Foresta 8x32 eyepiece looks purplish and is 2.4mm. I guess the difference in diameter might be to match the size of the objectives, which are greenish on both.
In the summary of the Sherman Pro 8x32 review at Allbinos it is only in respect of light transmission that it was favourably compared the to the Action EX, which is said to be in the same category. Instead I found Foresta 8x32 and Sherman Pro 8x42 to be most remarkable for their sharpness, for maintaing focus nearly to the edge, and for relatively minor pincushion distortions.
They are indeed at the bottom end but my examples have decent focus snap, contrast, and colour, and good brightness for the price. The porro configuration probably helps and also makes for a comfortable and stable grip, along with their 750gms and 850gms, neither feeling at all heavy. Maybe it's the large and fancy '5 element' click up eyepieces, Sherman 4 positions, Foresta 3 positions, which help to make them so easy to line up and use, especially Sherman which needs one click up for me with glasses, while Foresta needs to be right down.
All else being equal, 8x42 usually seems to give the impression of a bigger 'overall picture' than with an 8x32, which is also the case here. Also, although they are both quoted as having f.o.v. 8.1 degrees, the view of Sherman 8x42 seems to be noticeably wider than that of the Foresta 8x32. That is the opposite of what might be expected but may still not quite be 8.1 degrees. The view with Sherman 8x42 is a little brighter than Foresta 8x32, but in addition it does not seem to darken towards the circumference. In performance terms they both stick with it until higher in the general price range. Then sharpness is still every bit as good, although clarity and contrast begin to lag behind, but there is no dramatic difference.
Build and quality control are another matter. The Foresta only has plain objective caps and the linked rain guards were too tight. The Sherman has rain guards and push in drop down objective covers which all fit perfectly. The Foresta was poorly aligned and the Sherman nearly right, but its dioptre adjustment had barely enough '+' to suit, where it should have been near zero for me. The Foresta could have been on the shelf for years and had impossibly stiff focus, with 15 degrees of free play. The Sherman has firm but acceptable focus action but no free play (yet!). Closest focus is as long as 18ft with the Sherman, much less with the Foresta until the porro barrel separation makes it pointless.
I still enjoy using the Foresta 8x32 but think the Sherman Pro 8x42 is significantly better. Highly recommended, if you can get a good one
