Latest Update...

By the Imperial Decree of Adam Goi the First, Baron of the Red Lantern Alleys,
All reserves are upgraded to Main List... See you all tonight.

 

[Chiacj]

I'm no. 59, like to withdraw from the list as something crops up, let someone else take up this opportunity instead.

 

[Exposure]

hi hi, can i still join in tonite ? S74XXX19A

 

[benjamingan]

Just flew in. Cannot attend. Accept penalty. Please give next person in line my spot

 

[yhchoong]

My sincerest apologies, got held up by a last minute meeting in school. Am rushing down on the way from NTU now but doubt I'll make it. To those that I selfishly deprived a spot of, I am truly sorry.

 

[TheTerror]

Last minute something caught up.. my sincerest apology. Please proceed with my penalty. Thanks

 

[Adnix]

Thank you David for spending time to share with us today!!

 

[qingtian]

Hi David, it was nice to hear from you in the event. :thumbsup:
I guess those who had attended the event had definitely benefits from the talk.

BTW those repairs manuals that you kept are indeed :bigeyes:
A BIG THANKS to CS organizers and David for the hard work put in for these event.

 

[Jeremy1]

Hi David, thanks for the great talk.

Guess after listening to your talk, really need to think twice before disassemble a lens. And great material you have there.......

 

[Edwin Francis]

Thanks David for a very informative session. Hopefully you don't get flooded with too many PMs asking how to put a lens back together again!

Also thanks to the Mods and anyone else who helped organise everything.

 

[weiteck]

Impressed by David. can tell that he is a very meticulous person.
definitely a keen eye for details & he explained the topic & steps systematically.

 

[jungle_sg]

Hi david i was a happy customer of yours and now my general knowledge on camera had improved, i for one would not dare to diy as i am not a diy person at home! thanks for a great talk

 

[syphrix]

Thanks to all organisers and david for the informative talk! Gained some knowledge on how to check equipment and opened my eyes on how the internal of a lens looks like.
Thank u all.

 

[fatigue]

Thank you very much to all those who supported this event.

 

[eleveninth]

[jed091270]

Thank you very much to all those who supported this event.

 

[noraa80]

Thank you very much to all those who supported this event.

Is there any Webcast ( e.g. you stream ) or you tube that we can view that event ?

 

[slaam]

Is there any Webcast ( e.g. you stream ) or you tube that we can view that event ?

Thanks to Adam for organising, and also fatigue for the helpful tips: Took notes .. intend to post it later.

But here's a useful link that recaps most of what fatigue talked about
http://www.petapixel.com/2011/09/27...feed&utm_campaign=Feed:+PetaPixel+(PetaPixel)
If a camera lens has been abused, mishandled, or is just plain worn out, there are telltale signs that a knowledgeable buyer can look for to help appraise the value or lack thereof in a used camera lens.
Glass

The glass of a lens can have numerous problems. Most easily detected are scratches on the exposed glass elements. Sometimes, lighter scratches caused by poor cleaning technique can be present and are more difficult to detect. Bright reflected light is usually sufficient to see “cleaning marks”. Examine the lens with the light reflecting off surfaces at several angles and you should be able to tell if any light scratches are present.

Blemishes

Lens elements are generally &#8220;multicoated&#8221; with layers of nonreflective optical material. This minimizes light reflection and the resulting lens flare and ghosting associated with the multiple reflective surfaces of these complex optical devices. &#8220;Blemishes&#8221;, areas in the multicoating where material has been smeared or removed by a bump to the glass, manufacture defect or a solvent splash are less critical flaws provided they are very small (< 1mm diameter) and few in number. A small blemish shouldn't affect image reproduction. .....

p.s. I was the chap who registered via SAM and was seated at the front right corner, rofl was asking fatigue if the seat is taken and I didn't know he's the speaker!

 

[flashdance]

Thank you to the CS moderators who organised the event and also to bro fatigue who shared with us his vast experience and wealth of knowledge in handling and cleaning of camera equipment.

Thank you to bro Slaam for the helpful link above as well. I'm sure it will help reinforce what we heard at the talk. cheers

 

[slaam]

Well I am hoping fatigue might share his slides with us and the rest who didn't get to attend.

Points that was new knowledge to me
to avoid spoiling screw mounts (esp plastic ones) e.g. to fix lens filter on lens, Turn counter clockwise (unscrew) filter (hear the click) before screw in prevent improper seating and ruining screw threads

To check for fungus on sensor
use f16 shoot and shoot a white wall, there shld be a uniform whiteness(?)


Oil on lens aperture blades cause overexposure (check this when buying 2nd hand lens)

use a Bright light source to check for haze, fungus, dust on lens (shine in all directions) A little dust won't affect pic quality, but haze and and fungus might and it might be irreversible damage
