use a focusing chart to test if your lens is suffering from front/back focusing or not as it will be more accurate.
the AF might mis-focused sometimes due to the fact that the AF covers a large area (esp when u are focusing on a small piece of subject)...front/ back focusing will be more prominent when you are using the widest aperture and for this case f/1.4....

get ur lens fixed if it has the problem, else it will be very annoying..isnt it?

erh, having video is a plus for DSLR esp during vacation where you wana capture some special moments in video. imagine already carrying 1.5kg of gears, you wouldnt wana carry another camcoder and would love to do it with ur heavy gear some may say the quality sux and this and that, but as said it is a BONUS to have that feature

AFAIK, sigma 24-70 DG EX has gear stripping problems on alpha but I tot that HSM will prevent that problem happening...Yes?No?

for me, vacations will be my handycams, small and light... otherwise, a cybershot...

i dont want to lug my $$$$$ camera + lens around..

Just wondering do you guys use the High speed memory card for ur camera? The sandisk Extreme III, the price seems high.. 8gb for rm 280 while d normal one just rm 200.

Does it actually make a difference? currently my A100 using Sony memory stick... when viewing photos r fast enough.. just when zoom 100% in ..like will lag 0.25 sec. not a big deal for me.. is Sony memory card consider high speed?

someone in singapore converted his a900 to IR =D

if you are in the A900 range, it makes a hell lots of difference... lag reduce, faster viewing, faster writing.. etc... more pros... 1 con - more expensive..

for 10MP cameras, dont really need Extreme 3 and above...

Buy the Kingston Elite 133X very fast oredi. That's only like rm80 for 8gb.

No wonder i find it ok in my A100.. The new memory card im getting is for A700. so wat best n economy memory card for it... Ianho, the Kingston Elite 133x?? good enough? Rm 80 vs Rm 280 is a lot of difference....I can save d money for smthing else like lens filter

I hav to do a serious budgeting after ordering the A700... though got it quite cheap but it comes with nothing... not even memory card. Now looking for a lens to go with it.. if getting a SAL16105 it will cost round rm 1650... A700 bought for rm 2880... + memory card n lens filter another rm 200 perhaps... total damage = rm 4730

How much was last time A700 bundle with kitlens Sal16105 when it first released? feel like is not really cheaper by a lot even i bought it now 2 years later.

I personally use the Kingston Ultimate 266X on my 40D. I also have the Elite 133X n tried it in the 40D n both are ok. I hafta point out that my cam has a 75 frame buffer though, so I've never felt any slowdown even with the slowest cards while shooting at 6.5FPS. BUT the slow cards really very slow when reviewing the pics on LCD. The 133X should be fine in ur A700.

Sigma 24-70 HSM DOES NOT have the gear stripping problem as it's internally focus by the motor inside the lens. It doesn't use the body's AF motor which solves the gear stripping problem.


I find that the Kingston Elite 133X works better on a700 as compared to a200/a300/a350. My formatting speed, recording speed and review speed is much faster on a700. On a200, i can't sense the difference between a 133x and a 66x card. On a700, my 66x card is slow.

Oright thanks for the card recommendation.. I'll look for the Kingston Elite 133x.. 8Gb for rm 80 is very cheap.. compare to sandisk rm 280... luckily i din on spot buy that from them when i book the A700.. Buying A700 cheap but cover back by the memory card ~

The A100 has a lot more buffer than the A200/A300. It scrolls through pics at a blinding speed when you review them on cam. Try it on the A200 and you will notice the lag.

The A700 should be the same as the A100 I suspect so a 133x Kingston card should be fine.

i got a used one for sale @ RM50.... interested?

i'm using a 4GB Extreme 3 and a 8GB Kingston 133X on A700.

Difference is after u shoot, if u immediately press play, the pic will take time to display and allow u to scroll and also to delete the pic. Extreme 3 can review and delete immediately.

If you're impatient like me, sometimes it can get frustrating. Especially after i take a pic, i wanna quickly review to see if the pic come out right and make some setting adjustment. Also, transfer time to PC is double of Extreme.

Yeap.. i did notice that on my friend A200... i thought is his memory card slow... but im not using any fast card either..on A100 view next photo omost no loading time at all.


cjlai: selling urs? 8gb for rm 50.. okey ah.. but veli bz to cod these few days. wait till i come back from hometown d week after next.


hokc77: does the 133x takes 1 second - 2second b4 can view the preview? if is not more than 1 second i think im patient enough.. right now my A100 takes like 0.5 sec(apx) to view

Seng_Kiat: Make sure Audio Signal is On, and you are NOT in AF-C (in AF-C, beeping is disabled.)

I prefer turning off the beep and using AF-A set to DMF, because you can override focus after locking focus on ANY lens (except the Sony SAM lenses.)

ianho: There is a big, big difference between the A900's 100% 0.74x viewfinder, and that of the 5DMkII and D700. The difference between the A900 and the 98% A850 is not noticeable though.

hanafinoor: You had the Sigma 24-70mm EX DG non-HSM - the HSM one guarantees no gear stripping because it is not screw-driven.

achew: Sweeet!

more than 2 sec, worse if you just burst continuos. You can see the last pic, but can't scroll back until it finish writing to the card.

Feel like selling my 50mm la. Didn't fully utilize it la. Don't know what to shoot with it also lol.

I think it's due to capacity.

I also notice that my Kingson Elitepro 133x 4GB is faster than Pendrive 8GB 40MB/s which is about 266x.

fully agree with u.... capacity does make diff in speed..... i tested my a300 shoot burst mode w my old CF... 128MB & 512MB..... they can read n write even faster than 8GB

check the card spec before buying...

ur JPEG/RAW + Megapixel influences the choice of your card...
if using A900 + RAW/X-Fine Jpeg, definitely at least ExtremeIII and above..

for A100/200/300/350/700 JPEG = 133X Kingston is more than enough...

another thing, when the card is almost full, it slows down abit.. notice this on my CF ExtremeIII 16GB... about 70-80% full, then the slowness creeps in...
