Hi all, I'm a new owner of schneider's 110XL lens, and I've noticed when setting the aperture to 5.6 (the lens' widest), a very slight sliver of the shutter blade remains visible inside the lens, around the extreme edge. Only when I push the lever a little beyond 5.6 (that is, "off the scale") does this sliver fully disappear. So, just where is the TRUE 5.6 setting? Is it when 5.6 is indicated, or is it when the lever is pushed a little beyond 5.6 (until no sliver shows)? Of course, this raises a related question: if the TRUE 5.6 occurs when the lever is moved beyond 5.6, does this mean that all other aperture settings are sligtly inaccurate? Thanks in advance!
