Can consider the Tamron SP90, or the Nikkor 105mm VR micro.
Macro lens. Get 60mm AFS is more than enough if you're just to shoot gemstones.

^ *drools*
Picture so blur, cant really see what lens are those

ring flash

for macro shooting
so the subject will be evenly lighted or prevent harsh shadows if im not mistaken

new or 2nd?

if new mmg murah bangat..

baru notice ini, apasal post gambar say ni? bila curi ambik? i tak tau pun
itu 24 f/1.4 mmg chun, kalau saya punya bagus lor 
quite a number ppl do use silica gel, it's quite effective but u nid always replace or dry out the silica gel after some time
n the absorption rate is inconsistent, no guarantee is safe
can use Thirsty Hippo oso, but may risk drying up your equipment too much n the rubber will crack
well, i know ppl manage to get new at rm330 at Melaka
KL cheapest is rm370, some manage to get rm350
y not go for new instead if u cant get lower price for the 2nd hand 1, not much difference in price

I've just came back from sgwang and lowyat plaza surveying the price for 50mm F1.8 and the lowest price I get is

RM370

It range around 370 - 400

(Some even quote 420/430 and I just give them a shock face)

Recommended item bro , effective! I didn't realize how useful it was when I was only hearing stories about it. Only found out it was so effective when I finally bought one for myself.

Not sure if different brand makes differences or not, I use the original Lenspen.

I got mine for.. RM22 I think. If not mistaken can get for RM20 or so. Shashinki selling for RM35 or something tho .

Lens pen very cheap only la. The good 1 less than RM 20 can get already
