I just got a second hand DSLR. The previous owner did not use a dry cabinet but he did put a packet of silica gel inside. Must I get a dry cabinet or just go to Daiso to get a few more packets of silica gel?
if you're gonna invest lots in your lenses, and you know you're gonna stick with them in the long run, then get a dry cabi to at least ensure your equip is well maintained ... not a must but recommended
Overall, after some buying and selling and learning this hobby... I feel you need to identify the amount of lens you gonna get for your inventory. If you are sticking with your Kit lens, meaning only one complete set, then you do not need, like Bro Ortega said. Juz ensure you dun put it at places with high humidity, like near toilet / bathroom entrance etc. Keep in drawer with a pack of Hippo, and every 1 or 2 days, juz at least take out to snap one or 2 photos should be fine.
If you are increasing your inventory to 2-3 more lens, like Zoom / Macro/Prime lens and some small collection of filter, then getting a Dry Cabinet is more appropriate to keep everything in one place like Lord Soth mentioned.
I started off last year with a Dry box (free from Shop) then I got some new lens and filters as I slowly learned my needs. I did a couple of Buy and sell and experience and concluded i needed the Dry Cabinet. So I have one now. Looking at my inventory, the 36L is juz nice for my collection which will stop any new members currently =)
Dry cabinet is not only for photograpphy equipments... u can store important document, cds, dvds, tapes and even tea leaves inside.. For ppl who value their equipments and stuffs i think it is a must.. Too bad we are in a hot tropical and extreme humid country and not some cold dry countries and dun underestimate fungus.. u can clean it off but the damage to the lens coating is unrepairable.
I agree on the above replies unless you have quite small amount of equipment (a camera, 2-3 lenses and few filters) you can actually use a decent good quality air-tight container with amount of silica gels to put in it and stored in a cupboard, an additional you can also add another silica gel into your cupboard as well for double protection.
