Lee,
I cannot believe this and have not made any such observations. A simple DOF-calculation will show you, that there is plenty of DOF on your easel and EL-Lenses do usually have excellent field flatness. Sometimes when the focus knob on my EL-Head is too far away, I do focus by lowering or lifting the geared easel table on my Durst 139. I'm always surprised about how much I can move the table without losing focus while watching though a 10x grain focuser. </td></tr></table><span class='postcolor'>
what can I say, your experience is different than mine. I use a Peak and I can see the difference even at 8x10. YMMV....
