Lenses / Re: Hello Old Friend.
« on: October 28, 2013, 06:17:59 PM »
Have you ever went back to any old favourites?

Only with ladies and other gaming devices.

Old secondhand ladies, ewwww!!! Aren't they kind of loose and saggy?  :-X

6D pros: better high ISO (at least 2 stops in raw), bling factors (wifi, gps, movie, etc), better LCD screen

1Ds3 pros: better color, better AF, better build + weather sealed, larger battery, robust shutter/mirror (all metal), 100% VF, 0.76x VF magnification, faster responsiveness, 2 card slots for backup/separate recording

They are made for completely different purposes.

In fact I have replaced my 1D3 to 1Ds3 two months ago and never looked back. It feels just like the 1D3, but the VF is a lot bigger and brighter, and the images are better.

Lenses / Re: Is it still the time for the 16-35 ?
« on: October 27, 2013, 07:35:46 AM »
I actually found the 16-35 II very good. Wide open for centre sharpness and stop down to f11 for corners.

Most people who states that the 16-35 II is not sharp in the borders / corner does not know the fact, it has very pronounced field curvature at 16mm. Try to manually focus to the infinity mark, stop down to f11 and shoot a
landscape photo, you will find that the sharpness across the frame is actually very good.

There is about 2% area from the picture corners (and I mean the dead corners) that is a bit less sharp at 100%. The borders are totally sharp. If you are so obsessive about sharpness in the picture corner, then forget it and get the Nikon 14-24 and adapter.

Overall the 16-35 II's build, AF speed, ability to take filters all makes a very versatile event/landscape lens.

Take a look at my flickr account for landscapes shot using 16mm f11

Lenses / Re: How does EF Mount compare to other mounts
« on: October 21, 2013, 05:48:26 PM »
EF is pure electronic, unlike many others, which still kept the mechanical aperture lever.

This made tilt/shift lens easy and consistent to implement.

Take a look at how many mechanical parts in a Nikon zoom lens just to keep the aperture work, and why Nikon PC-E lenses is an exception, you will see that EF mount is superior.

Also, have you seen any Nikon camera that can change Aperture value when recording movie? They can't, because of the mechanical design. To change / step aperture value, they have to activate the aperture lever, which causes the aperture to snap to the fully open value, then re-release the lever again to get to the target value. EF lenses on the other hand, could step aperture value in any direction and steps you want. So EF mount is better for video too.

Lenses / Re: why would anyone scratch off the red ring of an L lens?
« on: October 21, 2013, 05:19:37 PM »
There is a design/material issue with 24-105L lens (apart from the aperture flex cable which snaps after some years of use). The red ring is a brittle plastic ring which have some chance to spontaneously crack and fall off. I don't think all of the are intentional, at least I have seen / owned 2 24-105 lenses which the red ring cracked by itself.

Of course auctions of this type would not attract the red ring whores but apart from partially weakened weather seal around the red ring/focus ring, the lens performance is not affected.

That being said, the 24-105L is dubbed the 'kit lens' of Canon entry level FF cameras, don't put up your hope too high that it gives the best construction because it does not.

Also, is a red ring really boost your ego?  ::)

Lenses / Re: Bought Sigma 35mm 1.4, bad copies?
« on: October 15, 2013, 11:52:20 PM »
This post is my take on explaining why HSM is so crappy:

I personally won't buy any Sigma lens any more, until I can either see, or do a disassemble to make sure their motor does not use paint as the friction material any more.

I bought a crappy Honda because I knew what I was getting and what for, now just tell me how can I drive this babe at 200MPH. Just tell me. I floored the gas pedal and it still struggles at 80MPH, what's wrong with it?

I don't want to hear anything like "just buy a Porsche".

70-200 IS II + 1.4x actually give you quite good sharpness and color.

I used to have a 300 f4L (non-IS), which is supposed to be even sharper than the 300 f4 IS, however, after comparing shots of 300 f4 and 70-200 @ 200 f2.8 + 1.4x TC, I sold the 300 f4 without regretting.

Lenses / Re: Which Normal to Wide Angle Focal Length Matches Your Vision?
« on: October 15, 2013, 11:38:12 PM »
Lenses that matches my vision is varying between 16mm and 300mm, depends on where I am and what I am looking at.  ::)

It's impossible to put plane filter over a 180 degree fisheye, the math doesn't work that way.

You need a curved filter.

I see you have APS-H camera, which may be working, but it won't work on ff.

You can never shoot picture with your lens cap on*!

(* unless you are shooting a Leica)

EOS-M / Re: EOS-M + Sigma 30mm f1.4 DC = One sexy camera!
« on: October 07, 2013, 12:49:15 AM »
There is nothing sexy about it. The lens is disproportionally large and heavy. If you find that looks 'sexy', then putting a 70-200 2.8 on it will look sexier. :'(

Lenses / Re: Transitioning to Primes
« on: October 03, 2013, 07:02:49 PM »
If you made up your mind to trade all your zooms to prime, make sure you have 2 bodies and use them side by side in any serious shooting sessions. Otherwise you will stuck in the forever changing lenses back and forth and miss many shots.

Lenses / Re: UV Filter damage limitation on 16-35II
« on: October 03, 2013, 06:58:06 PM »
Lift and remove the rubber ring on the focus ring, remove the tape.

Rotate the focus ring, you will see through the hole on the ring that there are 3 small screws that are not holding a white washer. Remove those 3 screws.

Gently pull the front filter ring part, it will pop up, along with the plastic name tag on the front element.

Now you can use a pair of pliers to bend the filter inward from a point to make it a heart shape. Then it can be removed easily. DO NOT SCREW the filter out, it will damage the filter mount on the lens.

Follow reverse step to put the filter mount back onto lens.

Yes you can stop down the aperture of EF lens, just:

1. Adjust to desired aperture with lens on camera
2. Press and hold DoF preview button
3. While holding the DoF preview button, remove the lens from the body
4. The lens will stay in the set aperture value, until you mount it back and it will snap to wide open
