Ok, sorry for the delay in response. Lots to respond to, I'll try to respond to everything as best I can.
Also, before I begin, I also really want to thank all of you for your help. Your knowledge and help has been invaluable to me. I'm sorry I don't really reciprocate because compared to you guys, I really am not that knowledgeable or experienced in film photography.
Problem is 90% of my work is street photography. I did use the Nikon F90 for street before, but there are a lot of hang ups I have with using it on the street. The focus motor, mirror slap, and auto film advance are just so loud, it is a massive deterrent. The Hexar has really liberated me and allowed me to get more shots that are great than I would've with the F90. I just can't see myself going back to that. It is the perfect street cam.
The only thing I can think of is there is an Olympus Stylus Epic (Mju I believe outside of North America) that I can get my hands on for $30. I've heard it's good for street photography, though I don't know how loud it is. Maybe I can snatch that up while I figure out the Hexar. I was thinking of getting it anyways for stuff through windows, as the Hexar doesn't really focus through windows well 95% of the time.
You don't find anything wrong with my negs? How so? There are a bunch that look almost black, with light bleeds. I almost always meter on the important part of the frame, the other times I don't by accident.
I'm not really using an aperture of f/2. I only use that when it isn't light enough. The Hexar works like this. You set the dial to the max aperture to use. The camera will override that if it maxes out at the 1/250th shutter and will go for a smaller aperture. Which happens all the time outdoors. I don't think I've ever shot wide open outside with the Hexar. Those photos all most have used at least f/8, up to f/22. That's why most of them don't have shallow DOF. The one of the kissing I don't know - but it could lead me to the issues some have mentioned - sticky shutter/aperture blades.
For the most part, I have been using one camera, one film, one developer, everything the same. Only times I've dithered from this were with 2 F90 rolls and 1 roll of FP4. Everything else has been Hex + HP5.
The earlier notation about accidentally covering the exposure sensor could actually be true. I will be more conscious of that now that I checked the manual and know exactly where it is. It is really easy for one's finger to slip.
To the rest of you who said encouraging words and to not give up, thank you. I really appreciate it.
