hey sifu2,
would like to consult u guy what brand and what lens should i look for if I'm looking a set for shooting intraoral " inside the mouth "
I have a friend send a list of spec to me , but i rather confused what shd i get?
can anyone pls recommend:
Shutter speed 125                       
Aperture 32                       
ISO 200         

I dont mind for 2nd hand , budget not above 2k include flash.

yeah, this is what exactly i m looking for, that day i went and try, and one of the pro advise me to use F32 for intraoral , bcos alot of minor details to zoom in...
can u recommend me the brand for macro len and flash??

my budget not too high only. 2k + max.

Can you suggest me a ring light for a6000? Cos Sony use other brand usually need to buy adapter.
And is that any proper term for the ring light, cos when I google, I can't really find that kind of ring.

need to know ur end picture gonna place where first?
A4 print?
Web?
Poster?
billboard?

If poster u definitely need to have slightly better budget.

I think a lot of pro here definitely gonna bash me here...(picture is not about gear)
well sometimes, yes it is if you using it for commercial...

ok let me tell u what different from an expensive lens and a stock lens?
and also expensive camera vs cheap camera

LENS
Image quality and light
cheap lens cannot go down to f2.8, and also cant get so great picture quality once you cropped  ( most probaly you going to do that if you are taking dental)
where else expensive lens once you cropped majority of the time ur image is sharp enough to use

Camera
ISO/low light performance ( this over the year hit me most, other than that AF point, FPS , etc etc doesnt cause much on me)
Both expensive and cheap camera can set a ISO 800
but both at ISO 800 their noise level different, and usually cheaper camera has smaller sensor size and hence noise performance even worse.
but all these can be solve if you have a great lighting

Okay so back to suggestion....

if you still want to remain at RM 2k
Invest on strobe light( constant lighting), and take with your handphone. no point invest on DSLR or camera ( this about RM 600 for a set
or Ring light about RM 300 u can get a good one

it's ok, cause the place he use is control area,
he got access to all the light he has.

What makes terrible picture is because under expose.
most DSLR these day , if sufficient light will take decent photo

Base on what he described I really believe he want to use it for work.  I strongly believe what he will use is out from camera .jpeg. no time to go edit and adjust the raw file.

Seriously it's not about the gear, it is about the technique and application

Actually Im dentist and My plan is to take case report only, sometime when we wan to shoot the area of interest which is far back in the mouth, the cheek will block the light coming in thus many doctors use a ring flash.
and those aperture F32,F28 is suggested by our master dental team who also use ring flash for their photography.

Anyway, i got friend who use yongnuo ring flash with olympus mirrorless but when i try to attach it to my sony a6000 , cant even fit thru, so i would love to know any of you is good in this field that suggest me a certain model that i can directly order it from the store without adapter OR with an adapter also is fine but budget not high. Definitely not sony original ring flash which cost a bomb

my master use canon , but i m somehow already bought this a6000 with macro lens and had experienced it, just the back region need more light to come in , so definitely i need a ring flash right now, it just i need advise where and what to buy only. Do you have any shop to recommend me?
