forrest_hartman1 Posted March 12, 2003 Share Posted March 12, 2003 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!

forrest_hartman1 Posted March 13, 2003 Author Share Posted March 13, 2003 I should clarify that when I refer to this "sliver," I'm referring to the diaphragm blades, not the shutter blades! Link to comment Share on other sites More sharing options...
emrys Posted March 13, 2003 Share Posted March 13, 2003 f/5.6 is acheived when indicated. Link to comment Share on other sites More sharing options...
forrest_hartman1 Posted March 13, 2003 Author Share Posted March 13, 2003 Thanks for the reply, Mike. The diaphragm blades of my other lenses are always fully retracted at their widest indicated aperture. It seems odd that the Schneider 110xl is different; that is, when f/5.6 is indicated, its diaphragm blades are still blocking some degree of light. I thought the aperture lever may have needed some re-calibration, but I guess it's a feature of this lens. Link to comment Share on other sites More sharing options...
ole_tjugen Posted March 14, 2003 Share Posted March 14, 2003 I dont have a 110XL, but yours COULD be off. I have a SA 121mm f:8 which gives f:9 with the aperture lever at f:5.6! It is quite possible that the aperture setting is wrong. Link to comment Share on other sites More sharing options...
ben_hopson Posted March 14, 2003 Share Posted March 14, 2003 Forrest, after seeing your post I checked my own new 110XL and find that I do not see exposed blades at 5.6. They are concealed right at the 5.6 setting. Perhaps the scale is a little off on your lens. Good luck. The 110XL is a great lens! Link to comment Share on other sites More sharing options...
rainer_viertlb_ck Posted March 15, 2003 Share Posted March 15, 2003 my 110xl has a "true" aperture of 6,3 when it indicates 5.6. nearly all lenses of schneider and rodenstock does not have the true full aperture. if you measure the lense with a "ttl" system as the sinar booster you will realize this.....
