My poor, beleaguered D300. 90,000 clicks and it's finally giving out. Shutter lock is brutal now. Just to start, of course, I could get it repaired, but don't see the point in putting several hundred bucks into a five year old camera. Also, of course, I'm planning to replace it A.S.A.P. (D800 in 10 days time, ideally: peace out, paycheck(s).) But between now and then, any suggestions as to things I can do to make it easier to work with? It still takes photos, but to get the shutter to stay open I have to literally take my lens off between shots, hit the shutter release, and that usually puts the mirror back down. Rinse. Repeat. Or is this something that is actually fixable by me? Any suggestions are more than welcome.
