Back focusing is d tendency for ur AF to focus on the back of the intended subject...But I've been using this lens for quite a while and I don't find this a problem. Maybe I prefer to choose my local AF points so I won't go wrong with my focusing...But this lens do find it hard to focus on some low contrast objects or scenes. U'll find this a trouble.

Bout the noise it generates during focusing..I think it's alright. Not really audible outdoor.

i think you meant to say AF-C right?

AF-C, Burst Shutter & Spot AF

I see. Thank you very very much!

No need use spot also can la.

Local AF also same.

Hmm i see. so its only the focusing problem ah? Okay! Thank you!!

what's the differences?

Spot is better on a230,290,330,380,33,55. Because changing the local af spot requires SOOO MANY STEPS. unlike the others.

Someone using a way more expensive tool than me but dunno such thing? Lol

Jk jk.

Spot is centre focus only, while Local you can choose your AF point. Quite useful if you need to change your AF point.

But not necessary la.

nono...i know la..aiyoorr....because what we want is a 'dot' in the middle...for aiming....that's all...local will confuse the requested person

Panning not necessarily use centre dot what? You can use any AF points also what.

Which is my point. Use local, or spot, its really up to u. But i usually use Local for panning.

because i quoted my 'rifle style' panning previously..that's why i suggested Spot*....just my 2 cents

just got a 30mm f2.8 macro for rm400

Actually...Instead of spot or local AF point focusing method, I found manual focus is d best way to get a sharp subject when it comes to panning. The trick is to pre-focus on the point where u think ur subject would be passing by.

Agreed. Depending on the conditions and stuff, MF still can nail a pretty sharp pix, if you are good at it.

that is for subject moving horizontally, how about then they started to give distance?

I guess panning shots are quite 2-D..means most of d time subjects r swaying sideways..that's where the panning action involve huh, and that's how d background's blurred with d sense of speed. For subjects moving onto or away from the camera d sense of speed is added with Zoom Burst instead.

Sushi..Again!

yeah...true...because i was thought of how kysham took the GT shots, skyline one which the subject drove vertically

i guess it is all up to the user what result they want

Example of panning. Sucks I know.
