I) stick for nikon if u got extra money
II) get 2.8 for extra bokeh provided u gt a big budget~

well, seems meaningless la my suggestion. according to dxomark, if u want sharpest, is 70200 2.8, then 70200 4, then Tamron AF 70-200mm f/2.8 SP Di LD [IF] macro. n the tammy 70200 macro is so darn cheap n considerably good if compared to them..i believe i must have left out something.bt still u need to ask opinion from others that had hands on before..

2.5k you mean is not nikon brand?

of course cant compare to prime telephoto lens...but i need to learn more about photography first before i move on to next stage.

I never had any problem with AF because most of the time i off my AF XD

it doesnt have VR or VC(what tamron calls it) ..
the 70200 f4 nikon is darn darn sharp anyways.. bt it's f4 lar.

yeah.. 2.8 sure can be f4 la.. bt hor the price is rm3k difference! with that u could get a sigma 35mm 1.4, or a used 16-35 f4 nikkor ..

One more thing i am concern...my uncle said nikon's lens is tougher ...is that true?

Extension tubes are quite rare, since there's not really a lot of demand I suppose
Ahhh, no problems man, we all have the passion for photography what   
I sort of have the same problem as you haha, as in the diffuser being too long than the lens, especially when I don't use the ET
Perhaps can consider flash brackets? Or a smaller diffuser
I'm not familiar with Canon flashguns, but you should be able to switch the light to disperse right? Can also put down the flashgun's diffuser (if applicable) for extra diffusion 

Since when did you get a trumpet for your flash?     

On a more serious note, try attaching the diffuser cap first before fitting the softbox. 

Can get for 10 bucks at digicolor nia. Reason your lighting is harsh because all the power is still aiming towards the center of the softbox, you need secondary diffusion at the light source first to better distribute the spread of light.

My softbox pula too short  Since my 90mm on it's own quite long d, after adding teleconverter or ET have to ramp up ISO to maintain short flash duration.

Quite simple only la once you start to understand the concept. 

For macro, the more layers of diffusion, the softer the light, but the more power required from the flash la.

Bracket costs around RM100-200 I think, and most are dual flash brackets. Single ones are quite rare I think
Light stands as in those for strobist work?
I wouldn't really recommend them, you will want to travel as light as possible for macro work. The more your gears, the more easy you tire, and also easier susceptibility to handshakes @@
+1~
The softbox works really well for me, though it sure gets in the way sometimes
Still trying to find a smaller diffuser that provides the same amount of light diffusing haha, will update when I finally find/design one 

from a not-active forumer selling his lens.... 2470 hehe

by the way yesterday finally took back my repaired lens..damaged rm190 for cleaning 2470 fungus inside ...but i wait damn long because of jam lol... sit in bus stop like 1 hour 45 minutes....

demmm selangor holiday...make traffic more jammed than usual 

haven't test the lens yet.. only check fungus removed.

i just lazy go to YL >_<
so i just contact yannick, i duno i doubt they are actually same or what...

i bought body and lens from yannick twice and i notice plastic bag is YL camera lol... so i think his source is YL 

Regarding the dust in my D3200 viewfinder, i made a huge mistake by dismantle the focusing screen and super imposed screen. I'm not sure about other models design, but D3200 design is separated focusing screen and super imposed screen (with focus grid).

The dust is inside the inner side of super imposed screen, which is the side facing prism. I wipe with micro fiber cloth and now the screen is full with many fine scratch. The focusing screen too. The expensive lesson for me.

Anyway, anyone here know how much for these 2 parts? I know the focusing screen is around 100+, just dun know how much for the super imposed screen.

[attachmentid=3766545]

Yes, bro, as bold part, super annoying, 2 fiber dusts stick inside the super imposed screen and just on top of the 2 focus points, everytime focus sure will see it. I can wait for next day to buy the blower, but due to my own decision, i dismantle myself and wipe using the micro fiber cloth that come with the camera. I'm too naive to expect those cloth provided should be scratch proof and dustless compare to normal fiber cloth. That was last Friday night, 2 days before my wedding.

Yesterday night i just did a final clean up using contact lens cleanser and flush with filtered water, after that blow off the water using rocket blower without wiping. But is too late, i use my handphone camera flash as the light source, direct to the reflex mirror and i observe at the viewfinder, alot of fine scratch in vertical and horizontal direction. Although not really obvious after i put back the lens, but it become an 'imperfection' inside my heart, although it won't affect the photo quality, but i still feel it will.

No pain no gain.

Always better to pay and have it done by the experts ;-)

I dont even dare to clean the sensor

Only thing I dare to clean is the lens outer element front and back  that also I worried accidentally scratching it ._.
