/zimages/corio5.jpg Back on the 24th of April 2010, I walked down to Zinc Art Space for David Corio's talk.
/zimages/corio3.jpg He took pictures way back then, for New Musical Express (or more commonly known as NME!) A whole load of portraits turned back time to a young U2, for example.
/zimages/corio2.jpg It was also nice to bump into the entire rock photographer scene!
/zimages/corio4.jpg Spot me in the picture.
/zimages/corio6.jpg Who is she spotting?
/zimages/corio1.jpg Badly budgeted tattoo. :D
/zimages/corio8.jpg And not even a week later, on the 30th of April 2010, I went down to Republik Studios for Palani Mohan's talk.
/zimages/corio9.jpg Mixed almost non-existent light. Photography talks are very invigorating and enlightening!
/zimages/corio10.jpg I think Prakash Daniel took this picture. I love it! It looks very newspaper-ish, which is apt since he does work for a newspaper.
/zimages/auggif11.gif And once upon a time, that was their band name.
/zimages/auggif12.gif Good ol' young (old, young?) power pop and uh... man, I can't quite put their genre but according to their site, randomness. Which is a good description.
/zimages/auggif13.gif Hooray for not saying your genre is indie...
/zimages/auggif14.gif ...as indie is not very descriptive sometimes.
/zimages/julygif1.gif Moonshine: A Homemade Music Show, down at Laundry Bar, on the 8th of July 2010. Here's melancholic Rendra Zawawi!
/zimages/julygif2.gif Today's special theme - 3 to 5-bit GIF pictures! (2 to the power of 5 = 32, which is the maximum number of colors.)
/zimages/julygif4.gif Azmyl Yunor brings on the folk.
/zimages/julygif3.gif It's not that straightforward to make a GIF conversion that expresses detail in all areas. A fair bit of dodging and unsharp masking is necessary.
/zimages/julygif5.gif Jangan tak rock!
/zimages/julygif10.gif Cynosure.
/zimages/julygif6.gif The NEX-5 with 16mm F2.8 pancake comes in real handy here...
/zimages/julygif8.gif They bring on hard rock, 90's style (think Stone Temple Pilots, yeah!)
/zimages/julygif9.gif And of course, fans and supporters.
/zimages/julygif11.gif Then was Mari Soul, who was lightly reggae-ish.
/zimages/julygif12.gif I'd seen them before as Mari Soul Faith Leaper...
/zimages/julygif13.gif ...when they covered The Foo Fighters in a previous Moonshine Tribute Edition.

/zimages/boilerroom3.jpg 18th June 2009: Miss Boiler Room finals, at Boiler Room, below Breakers, in Desa Sri Hartamas. Unfortunately the iconic Hartamas Square, Breakers, Boiler Room, Coffee Bean and that club at the end which always changed, have been demolished.
/zimages/boilerroom2.jpg The introductory stage.
/zimages/boilerroom1.jpg Too many dudes getting in my way argh.
/zimages/boilerroom7.jpg Casual wear, apparently.
/zimages/boilerroom5.jpg In line.
/zimages/boilerroom6.jpg The girl in focus does have a way of standing out of the crowd.
/zimages/boilerroom8.jpg From the main stage to take another group picture.
/zimages/boilerroom9.jpg Somehow, I do not find 1-piecers pretending to be 2-piecers appealing.
/zimages/boilerroom10.jpg That is more like it.
/zimages/boilerroom11.jpg Confidence is sexy.
/zimages/boilerroom12.jpg Ah, how I wished I had a dSLR with Live View back then.
/zimages/a580p2.jpg So I tried the Sony Alpha DSLR-A580 - the less famous cousin of the Sony Alpha SLT-A55V. Its sibling, the A560, was delayed to 2011. It has a real nice grip to it, with a nice embossed mode dial.
/zimages/a580p1.jpg The firmware is interestingly, Version 1.11.
In the menu you can choose Contrast Detect AF or Phase Detect AF to be used in Focus Check Live View.
In the A550, it was called Manual Focus Check Live View. Now that the camera can focus in main-sensor Live View (which is what Manual Focus Check Live View is, really) it had to change its name.
Phase Detect requires that the mirror drop back down so it can direct light to the Phase Detect AF sensors in the bottom of the camera.
Contrast Detect just uses the main sensor Live View to focus, albeit a lot, lot slower. At least the mirror does not move.
I recorded a video to show this.
Yes, there is no autofocus in video! You cannot manually focus and get a focus confirmation either! (The A55 and its sibling, the A33, show focus confirmation because its phase detect AF sensors are still seeing the view.)
A lot has been improved or brought back, but in essence it's still an old concept, based on the SLR idea. Translucent mirrors like on the SLT-A33 and SLT-A55, however, are an interesting way to tackle the limitations of the SLR focusing/viewing design!
After updating my NEX-5 to firmware v3, and my LA-EA1 A-mount to E-mount lens adapter to firmware v2, it could focus with SAM and SSM lenses, even when recording video!
I have to say, there were many things people were all waiting for with the firmware update; the customizable keys were one such great improvement. Here is what is different:
1) you can customize Soft Key B (bottom button) 2) you can customize Soft Key C (middle button) with 3 slots; you choose between slots by pressing the left and right keys 3) when you move the MF Assist position, and you enter MF Assist mode again, it remembers the position 4) you can choose to jump to the last item you accessed in the menu 5) you can scroll through the front and back of the menu list 6) you can now autofocus SAM, SSM and other in-lens-motor lenses (Sigma HSM, Tamron USD for example.) 7) you can set the aperture before recording a video (with E-mount and A-mount lenses) though you cannot change aperture while recording video
There were limits though - some options can be in Soft Key B but don't show up in Soft Key C and vice versa. I'd like to have ISO for Soft Key B and MF Assist for Soft Key C - MF Assist in Soft Key B cannot be used with E-mount lenses. However, the firmware came with the best options out of the box, exactly how I would have planned it:
Soft Key B = MF Assist Soft Key C Slot 1 = ISO Soft Key C Slot 1 = White Balance Soft Key C Slot 1 = DRO/Auto HDR
How the NEX-3/NEX-5 autofocuses with A-mount SAM/SSM lenses
And so after updating the firmware, I brought my A55 to compare it will all the Sony SAM and SSM lenses available in Sony Style KLCC. Unfortunately the Sony 300mm F2.8G SSM is not on display, and the Sony Carl Zeiss Distagon T* 24mm F2.0 ZA SSM, Sony 35mm F1.8 DT SAM and Sony 85mm F2.8 SAM had not arrived in Malaysia as of time of recording this video.

Sony SLT-A55 with ECM-CG50 shotgun mike comparison
Compared the Sony SLT-A55 with Minolta 24-50mm F4 (a screw-drive lens, sure to make a sound when focusing) and the ECM-CG50 shotgun mike in three situations;
1) using on-board mike 2) using ECM-CG50 shotgun mike 3) using ECM-CG50 shotgun mike with low cut filter on
/zimages/ecmcg501.jpg The holder itself has rubber to form an isolation mount - this prevents vibrations from pressing the camera buttons, from reaching the mike. The iISO to ISO coldshoe adapter (it cannot work for flashes) is included in the package.
VERDICT?
We can observe certain things - for one, the average video length with the NEX-5/LA-EA1 combo with SAM lenses was 30 seconds (minus the introduction.)
The average video length with the NEX-5/LA-EA1 combo with SSM lenses was 20 seconds (minus the introduction.)
Meanwhile, the A55 videos clocked in at an average of 4 seconds (minus the introduction.)
These were all for 3 cycles, focusing close, then further, then close again. I had to adjust my shooting location to accomodate lenses that could not focus so close, like the telephoto lenses.
Contrast Detect AF, especially on the NEX-5/LA-EA1 with Sony 30mm F2.8 DT SAM Macro, was particularly loud! This was probably because the NEX-5/LA-EA1 decided to go all the way to minimum focus distance (MFD), then to infinity, then back, then to the focus point.
The camera tells the lens motor to go at full speed from MFD to infinity which causes that loud sound.
Compare this to Phase Detect AF, where the camera just tells the lens motor to go to the focus point (quite simply, because it only needs to look once to get it in approximate location.)
Contrast Detect AF also seems to be a lot faster with shorter focal lengths. The Sony Carl Zeiss Vario-Sonnar T* 24-70mm F2.8 ZA SSM in particular proved to be the fastest in both contrast detect and phase detect situations.
Contrast Detect AF also does much, much better with brighter lenses.
The NEX-3/NEX-5 has another handicap - you cannot set the AF point to be fixed on the center; it will always go into Wide Area AF whenever it records video. The A33/A55 lets you change AF points even when recording video!
