Hey guys, please help me out with this issue. I got myself a wista sp today in the mail but im having a bit of trouble with the front rise adjustment. In the manual the left side has the locking screw the right is for adjustment. Your supposed to loosen the left before you adjust the right, but that locking screw is very very tight. I cant loosen it and i dont want to put a ton of pressure on it or force it. Is there something i am missing here? Is this a malfunction? Thanks in advance, here are some pics to better show it. First two are of the left side thats stuck, third is the right side that unscrews freely. Fourth is the manual im using. The knobs are not bent on the camera my phone is distorting the close up image. Well the more i look at it the more it seems slightly bent inward.
