They make a Pro version that can hold FS7's and Usra mini's but it's $900 instead of $500
I have the Longer Edelkrone but now that i have this shorter one I realize
i don't need a larger/longer one Most slides are about 5 to 8 seconds long in almost movies you watch
unless it's a dolly move thru a hallway or something like that
If you're making Full length films then yes a longer one will be better
but for youtube and social media films this small on is all you need (IMO)
best regards, Rick
