Price drop for Kx Body/Kit/200mm/300mm lens kit :)

[woefulwabbit]

Thanks guys for the welcome. Yes, I did register this nick in light of joining CS & the Pentaxian community within.

I was really sold to the 7D, but then I realized I was the one making the camera look so sexy! *ahem* ok back to earth... In all fairness the 7D is a handsomely built SLR but I simply can't resist the K-x's value! Definitely the best entry-SLR I have seen.

Actually, if you were thinking of getting the 7D (~$2400 body only), you might want to look at the the Pentax K-7 (~$1338 body only limited time offer until CNY + ~$430 for WR twin lens kit) too. The camera features are on par with the 7D and the performance a little bit behind, but like the K-x it is much cheaper and value for money.

I'll put in my 2c here...

If you are using the K-x, Class 6 is sufficient... even for shooting HD video. Never had any problems at all till now. But yes, Class 8 will be definitely better from a technical point of view... but Class 6 - 8/16 GB will be better for a value for money point of view... at least for the lifetime of your K-x.

At the moment, in Singapore, the Class 6 - 8 GB cost just a bit more than a Class 4 - 4 GB or Class 6 - 4 GB.

Remember, after two years, even a Class 10 card will be considered to be many times slower than whatever Class xx cards will be available then (Class 20, 30 ???) :think:

Even storage capacities will commonly be available from 64 GB and 128 GB over the next two years and quite likely at today rates for a 4 GB card. Therefore, today's 4 GB cards will be worth almost nothing at that time... so don't overpay for today's cards if you don't need to excess speed for your current camera or other devices! That's basically what I am suggesting here.

I laugh whenever I look at my 32 MB and 64 MB memory cards from just a handful of years ago! I used it for nearly a year in my 1.3 megapixel digicam then. That 64 MB card cost me the same as what a 8000 MB (8 GB) memory card does today! Get the picture?

there is another question on the charger is the quick-charge will damage battery or not? i have a energizer charger that take 1 hour to full charge the battary...slow charge better or same???

Slow charging better. The faster the charging, the hotter the batteries get. They don't like heat, so for them to last longer, slow charge.

I was thinking about getting a class 10 sandisk. but when I see the price, W:bigeyes:W too expensive...

 

[clownpo09]

i think for me the class 4 mem cards' speed can more than suffice my shooting need. i duno which shooting style/situation need that much memcard speed.:think:

i am thinking for getting the 4gb class 10 to try out... just $40 anyway...:bsmilie:
the sandisk one write until like very fast - 30Mb/s that y thinking of trying...
4GB should be able to take quite a number of pic already right? if i only use JPG....

i think that is a need for shooting raw???
i don't know how big is a raw file.... but as you can see, CF card speed is much more faster than SD card... that y a lot of DSLR use CF card even it is bigger, heavier... the slowest CF card(in the market now) is about the same speed as a lastest class 10 SD card....

correct me if wrong...

can cf card be use for K-x?
so i tried continues shooting in raw using my sd class 4 card. i can only fire 3 continues shots then it stops a little. anybody tried continues shooting with their class 10 sd and k-x?
(although i think this things may only be useful when shooting in high speed/sports events etc)

SD card seems to be much slower than CF. k-x can't use CF.

The k-7 uses the SD card also. Probably gonna keep my 50D for a while.

 

[woefulwabbit]

The initial number of frames for continous shooting doesn't depend so much on the class of the card. The camera has an internal buffer which will collect the shots in the initial burst rate while writing to the SD card at the same time. Once the buffer is full, the shooting rate is reduced to match the speed of writing to the SD card.

Compare http://www.dpreview.com/reviews/pentaxk7/page14.asp
vs http://www.dpreview.com/reviews/canoneos50d/page13.asp

They both do up to about 15 RAW frames before buffer full.
Beyond that, a standard CF card on 50D is actually A LOT slower than the SD card on K-7, but an expensive CF card would be somewhat slower than the SD card.

How often are you going to need to shoot more than 15 continuous frames anyway?

shoot shoot continously hoping to get a good picture... :bsmilie:

No lah, I decide to keep not because of CF vs SD card lah.

My sensibility finally came back and tell me not to anyhow spend money and change here change there. Actually lose a lot of money like this. And 50D nothing wrong. Just Canon lens is expensive, but their IS really works very well.

Anyway I have access to k-x mah, so best of both worlds lor.

Anyway the reviews, 50d can do a lot more frames before slowing down, and also 6.3fps vs 5.2fps.

But I am not a sports photographer, so no use to me.

as the reviews, they are using a class 10 card to test...:think:
buffer full at 2.2... which mean after the first 2 shots at full speed then after that will slow down...
anyway, should be seldom use mode...

look like no true... as you can see in review, 50D can do 6.3fps on CF card without limit, which mean the card speed and cam speed is match the IO speed... but SD card still have a limitation and need Buffer time to save all shots before the next blast.

correct me if wrong.

You are understanding it wrong.

Frame rate 4.7 fps
Number of frames 16
Buffer full rate 2.2 fps
Write complete 9.3 sec

This is for JPEG. This means that the K-x will continuously shoot for 16 frames at 4.7fps before the buffer is full, after which it will still shoot continuously for 2.2fps for an unlimited number of frames until you run out of space. This is for the Class 10 SD card, with a slower card the number of frames will be reduced by maybe around 2, and the buffer full rate will be slower, maybe around 1.5fps

If you shoot RAW then you will get about 5 frames before buffer full (maybe 4 with a slower card).

look like no true... as you can see in review, 50D can do 6.3fps on CF card without limit, which mean the card speed and cam speed is match the IO speed... but SD card still have a limitation and need Buffer time to save all shots before the next blast.

This is correct, assuming you are shooting JPEG and using the expensive CF. Using the cheaper CF you will eventually fill the buffer. Shooting RAW you will get about 15 frames before filling the buffer. My comparison was based on RAW, so you can't say it's "no true"


For practical use, the class of the SD or CF card doesn't really make much of a difference except when it comes to the buffer full continuous shooting rate.

oh ok....
i saw now the sandisk cheapest CF card also have 30MB/s speed, while Sandisk class 10 also have 30MB/s only...
also even the sandisk website also say that there is a speed diff with 2GB card and 4+GB card...
http://www.sandisk.com/media/416788/80-11-01707_rev1_datasheet_ultracf_r1.pdf


and also notice all the high-end cam use only CF....:embrass:

aiya, just ask Nikon why on earth did them move from CF card to SD card since D40/D80 lah.

pretty sure they will give some reasons.

yes... reasons is very simple.... SD card is getting faster and able to meet the demand... and yet SD is smaller, lighter and much cheaper in cost...

but why D300s, D3x and Canon D5 markII still don't change to SD?



Sorry, if i have said something wrong and offance anyone... i just guess guess only
