Canon General / Re: Debranding a 5DIII
« on: July 09, 2013, 10:41:59 PM »
I cannot see any reason why we should debrand the equipment. People knows the equipment can still guess what they are. As for thieves or robber, they see a big lens and  big camera, they know it is a good target. so why go through the trouble? Before the maturing of DSLR, my Leica M4 and  3 lenses travel to Europe, Asia etc with me. I have never  have any  problem. I do not even use the "never-ready case".

Canon General / Re: improving IQ in landscape

Here is a 40,219 x 11,522 shot taken with my motorized head:

Great Falls by scrappydoggy, on Flickr

The moving water was a nightmare from a blending standpoint.  The photomerge in CS5 was otherwise easy, albeit time consuming.


There is something odd about this image though- like the white balance changes from a greenish cast on left to a magenta cast on the right. Or it could just be my monitor.

Nice work. Both pictures have re-enforce about ghosting that I have mentioned. Just look at the rocks that are next to the water. You can see it. Some rocks are broken up some are lighter color without a sharp edge.

Rather than using a WA lens which can lead to distortion, why not take numerous images with a zoom lens then photo-merge them together.
You will end up with a rather large image but, downsizing an overly large image will lead to a superior image, IQ wise.
Comments welcome!       ;)
It sounds very easy ON PAPER. In reality it is not an easy task. In the overlapping area of the two images, everything must be identical, otherwise you will have "ghost image" on the element that are not identical. In landscape shooting, if there are any movement of the grasses, leaves, branches due to wind. you will not have identical image in the overlapping area. You will end up with ghost, especially in pixel level.  If the picture has a stream, then all bets are off.  the flowing water will become the "ghost" in the overlapping area.
You can spend hours to make it almost perfect. Is it worthy of your time?? I only do photo stitching if I do not have any other option, or do it just for the fun of it. Using an UWA  ( with tilting) is still the best option.

And here's the body.

Yes! This is a paper model that you can make it yourself for 38 Yuen ( US$5.00)

I think it is a 'HOAX".
1. I do not think Canon will have a "EOS 3D" strap  to be used on a real EOS 3D that they do not want to be identified.
2. The edge of the strap looks like "flake fur". Will Canon use such kind of material for the camera strap?
3. The Chinese Text says " picture taken at the end of certain year" . therefore the picture is taken at the end of last year at the latest, may be even earlier.
I think someone is having fun with us

Bare-bone minimum: 5dc and 24-105.  if there are extra "allowance" left, bring either 17-40 for buildings or 70-200 for people that are not your family. You are used to FF, you are not going to be happy with the crop body.

No, because it will stay at home as I don't plan on dragging around a ~$800 dollar lens on holiday that weighs 200-400g more because of a system that I don't need. I have not needed IS to shoot with my current 50 1.4 ever, 24-70 Mk1/2 or any lens that "needs" IS. Like I said, A 50 STM f/2 with IS for the video and "I want IS" crowd would be great and I may even buy that next to a 50 f/1.4 II but IS on everything is just expensive and heavy~

EF 28mm f2.8 weights 185 gm, EF 28mm f2.8 USM IS weights 260 gm. This difference is only 75 gm. I do not know where did you get the 200-400 gm information. If you do not want to bring a $800 lens on a trip then would you bring a $1800 camera body on a trip???

The 50mm f/1.4 is, by far, my most-used lens.  I’m with you 100%.

I’m a little concerned that it might be slower in order to accommodate IS, but the 35mm f/2.0 IS gives me hop!  4-stop IS on an f/1.4 aperture would be a dream come true for me!

For those saying “why do you need IS on a non-tele with that big of an aperture?!”, well, some of us need to run and gun in low-light where a tripod would be extremely prohibitive. (for me, alpine starts while mountaineering. “Hey rope team, do you mind if I get out my tripod and and get some shots with mirror lockup?  I know that it’s 2am and dark, windy, and cold but ISO 6400 makes baby Jebus cry…”)

Keep the dram alive!

I'm with you there, IS is great for low light landscapes to keep the ISO down and ensure optimium aperture for DOF and also for handheld video where it is impractical to use a tripod- mountaineering is one of those applications!
I am with you too. I cannot see any reason for people to be "against" IS on standard and wide angle lenses. Just imagine when you are a tourist inside  any of the palaces or the great churches. Do you want your wide angle lens to have IS or not ?

PowerShot / Re: Best solution for really shaky hands
« on: June 08, 2013, 01:09:41 PM »
Go to the shop and ask her to try out the Panasonic LX-7, under $400. It has fast lens, fast AF and VERY effective IS. Picture quality is a cut above most P & S except the larger sensor one like Sony RX 100. Unfortunately, RX100 is hard to hold and in the expensive side, most of the Canon P & S have SLOW AF.

EOS-M / Re: EF-M 11-22mm f/4-5.6 IS STM Announcement Soon? [CR2]
« on: June 04, 2013, 12:50:56 PM »
I agree with @ecka... IS (nowadays) is more of a feature for amateur video more so than still photos.  I wouldn't take serious landscape or architectural photos hand holding my camera at 1/15s, although just having that ability helps.
There a lot of churches, buildings will not allow either tripod or monopod. therefore you have to hand hold the camera. You will want IS in that situation.

You don't really need a tripod for mirrorless cameras with small lenses. Half-decent gorillapod should be OK.
I would like to see you use a gorillapod inside Ventican or Versaille

:) me too.
However, that's not my point. There is a bigger chance to use gorillapod in such places, than tripod. Don't you agree?
With IS you may not need either one of them The whole idea of mirrorless is to  travel light ( both in weight and bulk). With a"decent gorrillapod" ( read it as larger) that defeat the purpose. With IS on an EOS-M, you can hand hold the camera inside the building within reason. If there is enough light, you can even use a smaller aperture to give you more depth of field.  Therefore this lens is good for still photography.

Did anyone else raise an eyebrow at the "IS" in that lens name?

I didn't think people really needed to handhold 1-second exposures at 11mm, but I suppose the technology does help sell lenses to novices.

It will be extremely useful for shooting interior architecture and night scenery. You can even use smaller aperture to get more depth of field.

Are both batteries hot or just the 20% one is hot???

Based on Bill Claff's data, The canon 30D has quite low readind noise. Any camera after that the read noise has been at least doubled up, includind the 1D-X.  Why???  Is Canon is going backward on the read noise???
