What are some of the important things you would need?
I have $10,000 to start my own business//landscape and portraits //just starting out so an//already own a Nikon D800e, Nikon sb700, a quality tripod a few budget lenses and will be receiving a Nikon 16-35mm f/4, a Nikon 24-70mm f/2.8, Nikon 70-200 f/2.8 and a Nikon 85mm f1.4 shortly.
So other than the camera and those lenses, what are some things I should look into? trigger, studio lights (portable lights?), filters, other lenses, etc.
The business and marketing side of things is what determines if you will fail or succeed. I have not read any of the other posts in this thread, just responding to your PM.
I would not waste money on an 85/1.4. Just get the new 85/1.8 AF-S G. GREAT lens, good to own for its critical sharpness and light weight and HUGE price/performance. One of the finest 85's on the market; I have no idea why Nikon's 1.4 model even exists. SAVE the MONEY the 1.4 costs--do NOT spend the money on an 85mm 1.4!!!!!
Landscapes: primes are sharper than zooms. Significantly so on the D800e. Go to DxOMark.com and read their D800 lens suitability report. The 16-35 VR is very sharp for a zoom. The 24-70 and 70-200 are good zooms, and will be fine for a lot of uses. You have a good lens kit with those three top-class zooms and an 85/1.8 G.
Computer capability is a necessity. Lightroom 4 for sure, and some good actions for portraiture and wedding workflow. Remote release for shooting without your hand on the shutter button.
Lighting:The following is
my opinion after 27 years of Speedotron ownership. I looked at the Paul C. Buff kit. Wow...a great kit for Paul C. Buff's bottom line. Almost $3,000 and not much that's very sophisticated for CONTROL of the light. Needs more light SHAPING TOOLS. I would not spend money on Einsteins--they are wayyyover-priced and over-engineered for portraiture. Lots of high-tech specifications and uselessly technical bullspit specs that look good on paper and mean literally chit in-studio for portraiture. Over-priced, and not what a portrait or landscape shooter who is starting out,and is on a budget,really needs. 1/10th f/stop repeatability, ultra-short durations? Yadda-yadda.
4 monolights x 640 Watt-secons...just... wow, what a bad,bad allocation of power. Buy a pack-and head system with one big pack, and one small pack, and at LEAST five decent flash heads to start. Buy it used. Buy Speedotron for value and dependability and modifiers that WORK, and heads that will not break when they get dinged, banged, dropped, or worked hard. Speedotron's mylar snap-on diffusers for their 7 inch and 11.5 inch and 16-inch reflectors are a lighting necessity. One, or two diffusers per reflector can make a world of difference. You will sooner rather than later need at LEAST five flash heads. You need two 11.5 inch reflectors, and four mylar diffusers,and a 20 and a 35 degree honeycomb for the 11.5 set. You need three 7-inch reflectors, with a full honeycomb grid set, and six mylar diffusers. You need four sets of barn doors, two for 11.5 in ch, two for 7 inch, and one set for a 16- or 20-inch parabolic reflector or beauty dish.
Two, 46-inch Photek Softlighter II umbrella boxes. Or three of them. A Photoflex 36x48 softbox. A long strip-box with grid, from e-Bay. Two of them, ideally. A pair of Photoflex convertible umbrellas. A Manfrotto or other heavy-duty boom stand with 15 lb counterweight. Seamless paper rolls, white, gray, black.Crossbar and stand set-up, preferrably
Bogen Autopoles and crossbars with Expan Chain Drive system. Gaffer's tape, plenty of it. Some Bogen creative gels for the lights. Bunch of reflectors, at least one or better yet FOUR, the size of doors, and some way to join them (clips, wire, cordage) to make V-flats. ONE SIDE WHITE, ONE SIDE BLACK. Fabric is handiest, but foam-board will work for non-location non-transportable ones.
You will seldom need more than 200 Watt-seconds from a Speedotron flash head whenh its part of a 4- or 5- light setup; their power is not doubly-inflated in the Buff-style...400 W-s from a Speedo 11.5 inch reflector will overpower August sunlight from 13 feet away at a very small f/stop (f/13) at 1/250 at base ISO...so in Buff-speak that'd probably be called a "1000"...lol...and not in a funny lol way,either...
Don't spend a lot of money on expensive PER HEAD flash monolights like Einsteins when starting out....spend it on
light shapers and reflectors and diffusers and modifiers! I would rather have EIGHT crappy old Speedotron Brown Line heads and two, 400 Watt-second, 4-outlet Brownline D402 packs than four "640" Eisteins...I would have twice as many light heads, and many more options for modifiers and speed rings AND I would never worry it'd break if it dropped 3 feet onto carpet or just crap out in-transit. AND, I would save a ton of money too. Spend money on usefulness and real-word, old-school light modifying and shaping and not on sexy high-tech specs and minute, incremental 'control'; that is the B.S. that Buff's marketing lures newbies and geeks in with...spec-talk...tech-talk, the idea of incremental "control". You want 1/10th f/stop control over output??? Move the light stand 1 or 2 inches. And no, I am NOT kidding you.
