If u have the budget and want a better brand than HOYA, go for B+W filters, works better than HOYA filters. Cost a lot more too, but i think its worth it

If I'm not wrong, I saw the battery price is RM2xx at J-One yesterday when I bought my lens.

Just wondering,
I'm using a Batt grip, therefore using 2 batteries.
Each time before a major event, I'll charge them up although it's full bar. Will this affect the battery life span?
Cos a friend of mine said before, it would be better to have extra batteries, don't charge them before it's finish.
Charging before it's finish will shorten its life span.

Advise please     

I guess same goes to my Speedlite's 2AA batts?
Then i'll have to buy another set for each of them.

charging them and not using them, how long could they last? rough estimate la i mean

sometimes have no choice but to charge it because not everytime can use until depleted until next event or something. by the way this article is an interesting read on batter charger - go here

Yeah, i think the same goes to all rechargeable batteries. Hmmm.... im not too sure about that, word is they can last for around a week before they discharge itself. Some are worst, 1 or 2 days then it'll discharge XD
yeah true indeed, like what i did just now Just hoped that my battery can tahan hehe... btw today is very fine day for portrait shooting. Later ill post a photo

And thanks for the article! good read

i remember reading that battery nowadays last longer even if you dun fully use it before charging
surprisingly good weather today so next time you can teach us portrait shooting hehe. looking forward to your photos

for polarizer filer...sumtime it depens on what brand do u want. like me...i'm using HOYA barnd. ppl said that this brand was a branded stuff..so the price a bit higher. but i'm get the 2nd hand stuff..so its a bit cheap.

IINM this only applies to those old batteries that's using NIMH. Nowadays those batteries are using Li-ion and it's advisable to charge them frequently instead of only charge them when they almost kong.

try understanding Li-Ion batteries.
