The front filter is a standard 82mm filter thread , handy if you want to upgrade the hood for one that does something.
The rear filter should be the clear one , I've never needed the ND4 one myself.
If you haven't got the clear one , you can take the ND one out and cover the hole up with some insulation tape to keep the light and dust out .
That'll keep your shutter speed up .

The ND filter supplied is of no use for photographing the sun , you'd burn your sensor out , or you retina with a dslr !
The solar filters are very different.
To look at them , they look like a peice of tinfoil , rather than dark glass .

Hopefully next Monday we might catch the tail end of the solar eclipse.
If the sky's clear I'm heading up to the pennines to try and get a shot .
I need to be further to the west really , but you never know .
As I'll be focusing on the sun , I'll have the solar filter fitted .

Side by side comparison from the two lenses .
Hand held , Image stabilisation on .
With the 500 Reflex that's inbody only , with the 200-600mm that's a combined lens and body I/S .
Not a lot of sun spot activity today compared to a week back .

I've ordered up a step down rings to mount the filter on my Minolta 500mm Reflex , when I get it , if the Sun shows itself while I'm on a day off , I'll take a sample shot and post it here and a full size one on Flickr so you can see if you want to get one without buying one first .
IIRC the Reflex lens does a decent job of shots of the moon , so should be fine with shots of the sun .

Easily .
I used to use one that slips over the end of a telescope , but that type are very bulky .
This one is a screw in filter that you can keep in your camera bag of with a few others .
I got the 77mm one as I have other lenses that I want to use it on of that size .
With the 200-600 I just use a step down rings .
You don't need to worry about vignetting because you'll crop away more than half the frame anyway .
eBay link to the one I got. Other sizes available.
Starvue Solar filter

You'll need to unscrew the short hood off the reflex to put this on .
It's a type of foil that is very delicate , as fragile as tin foil .
That's why I got it small enough so I can still mount the lens hood .
Nothing to do with flair , just so you can protect the filter .The filter also has a forward facing thread so you can put the hood back on with the reflex .

First try using a new Solar filter for my lens that was a birthday present on my Sony FE 200-600mm F5.6-6.3 G OSS lens and the a7Riv , cropped a bit .
Shown my friends son, Anthony, his first view of the Sun as well and were greeted by a good display of sunspots .
He was worried about burning he's eyes out ( a sensible lad !) but I explained the solar filter to him , and the difference between OVF and EVF cameras .
He's still learning at 12 year old .
The view could have been better , but the Sun was already getting low in the sky and the clouds had started to form
This was taken threw light cloud , a few minutes later and the Sun was obscured .
Better luck in the summer !
