I used to keep my camera and lens in dry box. But it was too troublesome to keep track of the RH. So decided to upgrade to dry cabinet. I guess dry box is adequate as long as you keep track and maintain the RH.
Get time to go out and shoot... :bsmilie: and study your photos and ask how you can shoot better. Study other people's photos and ask yoruself why are they nice/not nice, and how you can incorporate techniques in your shoots
Protect and pro long the life of your camera. Get a dry cabinet 1st. A 30L doesn't take up so much space and would save you heaps of money if fungal starts growing. No point investing in lens unless you can protect them too.
After which I would think of a tripod together with a ball head, flash then lens....
Getting the stuff is not as important as getting used to the camera. The stuff can always come later, after you know the camera well -- the accessories are just to give you new things to shoot, and new areas of photography to explore.
Although I did buy UV filters for my lenses once I got my DSLR. Until now I don't have a tripod, not necessary for my shooting style. A CPL is also helpful. And of course, a good camera bag.
As for the dry-cabinet, silica gel sufficed for me, hehe
Depends on your needs. I guess what I'm going to advice here are a mish mash
Basics you can get first: filters like hoya, BW, etc to protect or enhance the lens, extra batteries, battery grip, waterproof bags like lowepro, etc
Or for shooting, it depends on your usage.
Night scenery --> tripod + wide angle lenses
Portraits --> prime lenses (depending on your preference also) + flash
Macros --> filters + flash
etc. It's hard to advice specially without you providing more info. For me I very rarely use tripods except to mount the flash. It's a different style+needs for all.
Depending on wat you shoot... tripod is not important in my opinion... I bought expensive $400++ tripod & ballhead as i do not want to been seen using cheap ones... in that time of 2 yrs, i only used it briefly once...
Lens cleaning kit: at least a blower, a brush, 100% alcohol or good cleaning fluid, some cleaning tissue. I see no need for sensor cleaning kit. You are not likely to touch the sensor and a blower should be enough. Fooling around with your sensor may result in a scratch or sth along the line.
