I became re-introduced back to the joy of shooting film by a spur of the moment decision to buy a F100 last year. Well a year later now I'm finding I like film more and more. One of the frustrations of course is that fact that I only have that one body. Naturally if I put in iso 100 film ... I want to shoot in some dark environment next and vice versa. So I've been looking for another F100 and I saw a great copy at the local shop. But next to it was a decent shape F4s. Mine has the split image focusing screen and I hope to find a few more and perhaps the fold up waist level viewfinder. The modular aspect of this camera is a fantastic thing to have. Now I remember the F4. I was shooting canon by then ... but what a lust object. So despite the lack of solid logic ... I got it. It's like a trip back in time. I've only shot one roll with it so far but it has been an eye opener. The controls of the "old" way ... so far are a struggle. I hate the interlocks. Not for being there but for being hard to find at this stage and being hard to press. I guess I have to get used to it. The solid feeling is marvelous on the other hand. I have a few questions that I can't seem to find an answer to. I have an SB800 and SB600 and thought that I could use those, independant of which camera I was using in wireless TTL mode. The F4 supports TTL ... but I can't make the SB600 fire from the SB800 when mounted on the F4. Is that the way it is ... or am I just not doing something right? The feature I have the most problem with are the full stops in manual mode. For slide film where a more exact exposure is desired ... how do you gents get around full stops. Do you use the exposure compensation to fine tune it? It seems a slow way to work .. but I can't think of any other way. Perhaps aperture preffered is to be preffered in that sense but the exposure lock button is a pain to reach for me ... and I wish that there was some way that it would lock exposure without having to keep the finger on the exposure lock button. Is there? The finger gimnastics are a bit tough for me. I know I will have to get used to this machine. I love the solid feel of it, and the little things like how slick the film transport mechanism feels and can see why some rave about the F4 the way they do. I've got quite the learning curve ahead of me and I'm looking forward to it - to spending "quality time" with my new old gem. It is almost like owning a piece of history and still a top notch camera. Wish me luck. Oh ... and .... any tips would be appreciated.
