One thing is for sure.......The Nikkor 10.5mm kicks butt. It is the undisputed king of lenses. No offense to all you sigma 8mm users.
I guess we could argue about that but look it up. It is not just me saying it.
I guess you could say I am biased because this is what I use. LOL
The DSLR is KING as well. Like the others say.....1 month on the learning curve and you won't look back.
What do you have to learn. LOLOLOLOL. We ain't in Kansas anymore Toto. You will have to learn to use the camera total manual mode without looking at the manual every time you need to set something on the camera. If you want to shoot scenes in 10 minutes or less then you will have to learn by experience what exposures to use in certain lighting situations. If you screw around taking test shots for 20 minutes and even take several bracket sets of the same scene because you are not sure what to do you will be on the job all day for a 6 to 8 scene job. You have to shoot 4 jobs today and you don't have time for all that screwing around. Time is money.
I can tell you exactly how long it takes to work with the D70+10.5mm setup. It takes 10 - 12 minutes to shoot 6+T+B and this is moving fast. This includeds moving to the new location, leveling the tripod, taking a few test shots to set exposure. Then taking the shots using a 3 frame bracket set at 2 ev. You can move faster if you want to make mistakes like forgetting to shoot the top or bottom, bumping the tripod, shooting a frame set twice, shooting your feet, shooting your self in mirrors, forgetting to set the correct white balance, and not checking to make sure the lens is set to infintiy focus and forgetting to turn bracketing on after the test shots. And a few other mistakes like rinkled bed spreads, garbage cans in the scene, uneven blinds, messy pillows, chairs not lined up, objects on tables, in chairs messed up and crooked pictures on the wall......
Post processing for me works out to be about 30 minutes per pano but can takes 1 hour. This includes combining with photomatrix, stitching, and then having to set matching points manually for the top and bottom which happens about 75% of the time. Saving. Touching up in photoshop. Importing back to panoweaver and adding the tripod cap. Re saving. Photoshop again to resize for delivery. If you have to blend in windows from two bracket sets which happens often due to my location on the coast. Water/sand/glare etc. just can not be captured correctly with 3 frames at 2 ev. But if you dont' have to worry about that then 30 min is right on. Of course post processing time depends on how perfect you want to make the images. But for "production" work 30 min is it. I have an old computer so if you have a scream machin mabey you can do post process faster.
Out side shots are a little easier but don't let that fool you. Moving trees, shade, mean dogs, huge biting bugs, heat exhaustion, un-level ground,.....falling of the sea wall or the dock and into the water ( it happens trust me LOL), Oh I forgot. Touching the lens and spending 15 minutes cleaning it. Or even sneazing on it, or sweating profusly from heat and letting that drop onto the lens......
The coolpix is great for some stuff. Easy to use. A lot of "auto" shooting and so forth. But if you want to run with the big dogs in the street instead of sitting on the porch then get a DSLR and a Nikkor 10.5 or the Sigma 8mm.
Besides the chicks will ask you to take shots of them and all the good looking realtor ladies will be very interested in your impressive looking set up. That little coolpix doesn't fill the bill sometimes. LOLOLOL. You Know "size matters" LOL. A little humor if you have read this far.
