Technical Support / Re: Zoom ring on 17-40L becoming loose?
« on: January 20, 2015, 05:04:37 AM »
Lift the zoom ring rubber up and pull it off, then you will see there are 2 holes on the zoom ring. There is a screw in each hole, use a JIS 00 type screwdriver to tighten them up. Put the rubber ring back and you are done.

Love to see a EOS M mount camera in this form factor, that would be golden.

EOS Bodies / Re: NEW CAMERA - EOS 80D?
« on: January 08, 2015, 10:38:37 PM »
It's definitely not a 80D or a replacement for any of the larger cameras. Looking at the relative size of the SD card slot, the buttons, etc, it's about the size of a rebel. Definitely based on the video that is a EF-S lens, so probably either a newer rebel or a new segment for Canon.

But can you possibly segment between 2 and 3 digits model numbers? 2.5 digits?  :-[

A rebel with top LCD! That's something new... Hopefully they will have the 20MP DP sensor and some improved AF system. But I won't be getting it anyway  ???

Tripod: You only realize when you bought the 3rd one, that the money spent on the first 2 should have been saved.

In other words, buy the most expensive one you can afford, buy once and save money.

I dusted my Panasonic GX1 (m43) and gave it a go again this morning, after 1 hour walk with the little camera in my hand, I had hand cramps  :'( :'( :'(

I was going to buy the LX100 but after this I'm not so sure.

Those girly small cameras are better left to the wives.

EOS Bodies / Re: Speculate: How much noise improvement from 5D3 to 5D4?
« on: January 05, 2015, 10:50:57 PM »
Don't expect high ISO noise improvement, Canon is going for low ISO improvements, better color, things like that.  Any High ISO noise improvement will be slight.  Of course, the new Digic 6 processor will produce jpegs at higher ISO settings and less detail, but the actual raw sensor output will be a incremental improvement.
The Dual Pixel sensor does have promise if Canon can do more things with it than they have shown on the crop cameras.  I suspect that there are some more tricks they can use and are reserving them for the more expensive models.  That is the standard sales tactic, whether its a iphone, a new car, a TV set, or a Canon DSLR.

There is no any indication that Canon will be working on improving low ISO DR. They said they are working on a high resolution sensor (no DR mentioned), they also stated that their sensor is the best (sigh...). All those EXMOR wannabe rumors are more like a wishlist than actual information, that's why it seems very depressing in Canon land.

I think from current reliable source, it's best to hope for the next FF sensor to be a FF 7D2 sensor: 52MP dual pixel, no banding, same 11.5 stops low ISO DR. Then you can only get positive surprise if it turns out to be more than that.

I'm currently trying hard to master the way of shooting sky separately (2 shots bracket, -2 to -3 EV) and combine in post. If done right it looks like you have all the DR you really need. The only situation I find that needs more DR is when bright sky is present.

I don't understand the motivation to bring out waves after waves of ho hum P&S every year or half. This only desensitizes your customer to ignore anything you announce in the future.

Time to stop paying attention to those manufactures for 6 months, see ya...

High ISO noise or low ISO noise?

High ISO noise maybe 1/2 stop better

Low ISO noise has a lot of room for improvement. If we are luckly (not sure atm), it could be 3-4 stops better  :-X :-X :-X If not, then it's 0 stop, which means no improvement :'(

Or if Canon can employ the on sensor, dual gain ADC, then it will be 5 stops better. One could dream...  ???

However I've already given up on chasing the shadow pushing mania. Even if it's clean when pushed 5 stops, the tonal range is severely limited. Better learn how to properly bracket and merge. Unless someone uses 16-bit ADC (or more) and gamma mapped raw encoding, bracket is a better option.

753mm?   ;D

No, it must be the 999mm they kept talking about!  :-X

Lenses / Re: Which Canon Full Frame Camera is For You?
« on: December 22, 2014, 10:07:49 PM »
LOL, Which one should I buy? None.  ;D

That's... sort of the opposite of what I was trying to explain, heh!

The projected image gets physically larger, hence acting like a zoom if you were to collect the light projected on to a 24mm x 36mm selection at the centre of the projection - the entire image is enlarged, you'd be collecting much fewer photons but the image is optically "zoomed in" and very sharp, sort of like a variable aperture zoom :)

Ok, then what's the different between your way vs say, extension tube? tele-converter? APS-c sensor? cropping in PP?

Either way you are cropping into the image circle, digitally or optically, which will inevitably reduce sharpness. If optically cropping does not reduce sharpness when a 2x TC won't give you any worse image quality compared to no TC, which is not true. You can't divide resolution without facing softness.

I just talk to my Photographer friends at the Town Camera club, and One recommend me to get This Fastest Lens CANON EF 50 mm F/ 1.0 L USM= $ 2500 to $3500.

"Fastest" :-) ... they say the af is crawling slow, and that's one reason why Canon dumped the lens.

Also note that you cannot much more light from very fast lenses on digital, part of the light coming from steep angles is lost on the digital sensor - so it's for thin dof only.

Slow AF = true

but oblique angled light, I believe we can fix it in newer generation of sensors so it's only temporary.

One major down side of this lens is the flare issue. You know, old coating and stuff, use it in day time is fine, but use it in the night is a complete mess, which defeats the purpose of a f1.0 lens isn't it?

Also when motor or electronic dies, you can't event focus it so it indeed becomes a paper weight, unless some very able man DIY modify it and gives it mechanical focus ability.

So in short: you are buying a historical artefact, a museum piece. If you are happy about that, when go right ahead.
