2-DA* 135=400mm f/4.0 lens that's fully sealed and uses SDM
3-Fully sealed flash unit with a GN of 60.
4-dual SD card slots
5-silent mode: Slow the FPS if need be, but make the sound of the mirror/shutter as close to in-audible as possible for photographing wildlife that might otherwise get spooked by camera noises.
6-ISO 25 & 50
7-make a limited series camera body to compliment the limited line of lenses, ie, not nessessarily perfomance driven, but rather a luxury class of camera.....compact, all metal body, S.A. & M modes only.
1. The SF-1 had an accessory grip that had a 1 meter cord for 4 AA batteries that went into the pocket. I still have mine, and the SF-1 it fits. When this winter hits (and it is supposed to the the coldest in 10+ years), I'm ready! Now, if I could get one for my K10D ...
2. You've got my vote for that lens! It might take me a while to get the $$$, and I will need a new backpack - the one I have is not big enough with those fat DA* lenses in it - I've had to put my 70-210/4 A lens in the outside pouch on my LowePro Trekker. (In the soft lens case for my 50-135 DA*).
3. Yeah! Yeah! Yeah! And with a stainless steel foot so it won't crack.
4. I'm with you. I shoot RAW - pretty short number even with 4 Gb SanDisk Extreme III.
5. I've never noticed troubles with the noise. Wildlife doesn't seem to consider it a danger. Some birds look, but if I don't move, not a problem. I have one great (film) series of a song sparrow singing that I took from about 5 meters out with the MZ-S and 400/5.6 M lens. Like our canary, he just tried to outshout the camera. I generally photograph within parks; perhaps the wildlife is just used to nuts like me.
6. Dunno. 100 seems pretty clean to me.
7. I don't have any interest in this one, but perhaps others ...
IMNSHO. Great list of Iwannas.
