newbiee, this

newbie:
phase detect = godlike that why DSLR core is phasedetect.
contrast detect = d**klike... so all compactcamera for ***ks so is DSLR equip with contrast detect LV...
(oh no i going to spark fire)

Where did you get that information from?

Yes, both of those lenses are fixed focal length lenses (also known as 'prime lenses'), one at 35mm and one at 50mm equivalent field of view. So, you can't zoom with them, you can 'zoom' with your legs though. Difference between the two lenses is in focal length.

There's no such thing as which lens is better suited for which body (apart from the Nikon D3/5xxx case where you can't AF with lenses without in-built motor). It depends more on what purpose you want the lens to work as. Do you need a wider or a narrower view? Go to the stores to test it out. Borrow the camera from a friend who has it and test it out if possible.

If you are really unsure of which to get and worry that you might get the wrong one, then just stick with the kitlens that comes with the camera for the mean time while you improve on your camera knowledge before investing in a prime lens.

that if you use the MF liveview check thingie. normal QLV using phase detect.

I've updated the front page regarding the A77 and wireless flash.

8tvt: Yes it is written on the package.

There is also a Sandisk Class 10 30MB/s but you don't want that for the A77.

e-jump: Nice! Love how the reflection is blurred out.

fansoption: Nice! It almost looks like a texture.

Newbieeeeee:

PDAF = faster because it knows exactly where to go once it has looked once
CDAF = slower because it keeps adjusting and checking

By nature the PDAF sensors are getting light that passes through the main mirror, reflects off the secondary mirror, into the AF chamber. The distance from the lens to the PDAF sensors should be the same as the distance of the lens to the sensor.

If not, you get a backfocusing/frontfocusing camera!

PDAF on sensor (which the Nikon V1/J1 supposedly has, but where are the tech documents?) solves this. Since there are no TWO distances, there is no misfocus from calibration error.

CDAF, because everything happens on the main sensor, does not have backfocusing/frontfocusing issues.

The A560/A580 uses PDAF in Quick AF Live View, and allows you to choose between PDAF and CDAF in Focus Check Live View.

waiting waiting waitng a77, no one sell, got sell also expensive. ok, straight wait for FF lol....

lol not tv la.. all i have..

proper digital frame ofcourse..

The dent cuz the lens drop from table.
See how la, see he wanna sell or not

Hi wanna ask any A77 user.
My A77 come with Sony SDHC 16GB, Class4.

Whenever after i shoot a pic, and I wanna delete immediately after preview, it will say something like, cannot delete as card is accessing or something..........anyone experience this? Will Class10 card be faster?

Please advice

boss i'm stuck between this 2 lenses... any sample closed up using sony+tamron 17-50? i'm looking sharp lens for my jewelry photography..
thanks

Use kit lens and raynox also can liao la no need sp90. Invest in better lighting is more important.

zstan: Where did he say that? There are some traditional names but Zeiss themselves ignore that. I don't know why the 85mm F1.4 ZA is a Planar instead of a Sonnar, for example, when Sonnar is supposed to be bright.

Newbieeeeee: Shouldn't be - ADI is better for reflective surfaces since it follows focus distance.

However ADI will be disabled when using bounce flash, wireless flash or a lens without distance encoders (5-pin lenses). This is because distance information is no longer accurate.

Also, if you use a filter that reduces light through the lens or flash, you will need to compensate.

gjtan: Weird crop.

jimlim007: Weird. I tried my NEX-5 with LA-EA1 with:

- Sigma 12-24mm F4.5-5.6 EX DG
- Sigma 17-35mm F2.8-4.0 EX
- Sigma 70-210mm F4.0-5.6
- Tamron 200-400mm F5.6

All of them have proper EXIF inside. Of course no SteadyShot or AF lah.

[/spoiler]

I can see that the clay figure when used with adi is actually more correctly exposed than compared to P-TTL. There's no blown highlights there.

As expected the bounced version will look the same coz both will be used in pre-TTL mode.

Newbieeeeee: Just checking - the flash that is mounted is your F42? It shouldn't underexpose so much in ADI.

fansoption: Show us bigger flowers! Wow the Nanoha Macro looks very interesting especially with the built-in LED illumination.

NutZ748: Yes the A77 lets you quickly choose AF points with its joystick.

razuryza: What he means is that you need to press the AF point selector button first before being able to select. On the A100/A200/A300/A350/A450/A500/A550/A560/A580/A700/A77/A850/A900 you can press left/right/up/down on the D-pad or joystick to immediately change AF point, without having to press anything. Pressing the AF button in the middle of the D-pad or joystick resets to the center point.

Aiyo.

I did state that when using anything that reduces light on the flash or through the lens, you need to compensate, when using ADI.

The manual for the Stofen would usually tell you how much +EV to add.

However, the Stofen is meant to be used at a 45 degree angle...

Newbieeeeee:

ADI knows what power to use based on the lens distance. So for something that is 5.25 meters away with ISO400 105mm zoom, it knows to use 1/32 power for the F42.

However, if you put a ND filter, a diffuser, or anything that can reduce the light bouncing from flash to lens, the ADI calculation is no longer accurate. You'll need to compensate as per the instructions - for example, a red filter may have instructions to compensate +1 EV. It's on the instructions that come with the filter/diffuser.

I say EV, not Flash EV, for simplicity, since on most Alphas, setting +1 EV also sets +1 Flash EV. There is an option on some to set "exposure sets ambient only" instead of "exposure sets ambient + flash".

You're not supposed to use these diffusers in a direct flash way - read the instructions.

hahahaha u dont get my point, it was a sarcasm for gearhead, sony does not make sensor for canon DSLR.

D7000 and D5100 is using A580/A55 sensor.

the unit not mine, i testing it only. and yesss the feature is very helpful

zstan: imagine this, softskin on aps-c image quality.
