EOS Bodies / Re: Stronger body?
« on: April 12, 2011, 10:02:48 PM »
This has been brought up before.  It's at your own risk of course, but there are tutorials online on how to either dissemble the camera and clean the contacts, or very carefully tilt the camera the right way and pour pure alcohol up the battery compartment (alcohol cannot have water or components can rust).  I haven't ever done either, but the logic is solid.  Can't say that I would do it though.  I'll have to decide when I run into that problem.

I see how to fix it (at you own risk) in You tube. My point is if the shutter release burtton fails the rugged metal body becomes aboat anchore. So why there is a lot of people on this site insist on metal boby or nothing??

It's cause of this that I'm not a bit worried about rugness.

I take good care of my cameras, they can take allot of abuse.

Maybe a rugged camera would take more of a beating or survive a harsher accident, but prevention is the best ruggedness.
How do we prevent the shutter release button failure?? It is a commonly failure item before anything elses in the 20D,30D 40D 50D etc. They all have rugged metal body, but the shutter button failure will cost US$250 to be fixed. I do no think that I will spend that kind of money on a 3 years old DSLR.

EOS Bodies / Re: The Truth about Microadjust

I mean think about it...60d doesn't really compete very well with D7000 and Canon has a big hole in their pricing structure between the 60d and the 7d. You'd think they'd just add a couple of firmware changes for the crop zoom and microfocus adjust, kick the price up a couple of hundred bucks and call it a 60d+. They'd sell the daylights out of it and why care if it canibalizes 60d since it's the same exact hardware, so the amoritization of development/production ramp up costs are unchanged? IMO it wouldn't affect 7d since people who really need 8fps, more sophisitcated focus, better sealing, etc won't flex down to something that doesn't have those features.
Totally agree. It is a VERY STUPID move for Canon to take away the micro adjustment from 60D. In fact, it should be a standard issue on ALL Canon DSLR including the Rebels.

EOS Bodies / Re: What do you recommend for beginner?
« on: April 12, 2011, 12:20:45 PM »
You're right. You're nuts!  ;D

I see your point, however, at least where I live, finding film and someone to do development of it is a) hard b) very costly. Almost no one has film for sale any more, only specialist stores and they charge you in blood for it. The gear may be cheap, but not using it.

It's close to using checks, I don't think I've seen a check since the late 80's.

See, I knew somebody would call me nuts ;-) And probably rightly so. And actually, I see checks all the time - and find that equally ridiculous.

And unfortunately, you are right about the limits in film availability, places that process (or what that call processing these days...), the cost, and the pretty dismal output you get from all negatives being cheaply scanned and send to one of these horrible printers these days. None of this comes even close to how things used to be.

BUT: I still think you learn a lot about taking pictures. With a few rolls of film in your bag at 36 exposures a pop you think at least twice before pulling the trigger given the cost and complications. If you can translate that later into the digital world I personally think it's an exercise well worth the effort. Very disciplined and determined people can do this maybe right away with a digital SLR.

The other part I was getting at is how wrong it is that we are still being force fed the notion that "full frame" is only for pros and snobby rich people. I think there is something very wrong with the fact that beginners on a budget learn photography these days in a cropped format where all the standards and numbers are off. I know, people (rightly) said that also when "35mm" became widely used. It is like checks in that sense. And I'm obviously old.

 
Both of you have apoint. I would suggest the following approach.
Get a used 40D or even 20D with a cheap used 17-55mm lens.  That will allow you to explore the DSLR and learn the technique with mininal cost.  There is another catch about people moving from point and shoot (or small camera) to DSLR. Some people may not be able to get use to the bulk and  weight of the 'New" DSLR. I have at least two friends are having their DSLR sitting in the closet for the same reason.  I do not quite understand abour the statement of "all numbers are off for the crop snesor". Are you refering  to the DOF or something else. Anyway. you can lean a lot about photography with a cheap used DSLR sysytem. Just do not form a habbit of clicking without thinking.

I do understand that a full size mirror with a normal swing motion would hit the back of an EF-S lens.
I believe the Sony A900 also has a mirror motion that doesn't swing out that much. The front edge of the mirror does not end up very far forward from where it started when a picture is taken. It's more like the mirror is "pushed" up rather than a "swinging" motion.

The mirror on the A900 is effectively getting the same result as Nikon( the "bigger" mirror moves back during the swing )

As far as I know, there is only ONE SLR have a side way moving mirror other than  a flip up mirror. It is the Olympus Pen F. That is another story. You can google it  if you are interested.

Nikon has been pulling back the mirror privot befor flipping the mirror up for a long time ( may be since F 4).

Interesting, I didn't know they did that.  From an engineering standpoint, it just seems like a really bad idea if you can avoid it.

Agree. It is not an ideal situation. However. that is the only way Nikon can increase the mirror size. In the OLD days. if a 200mm lens is used in a SLR (film). the upper 1/5 of the image  in the viwe finder is darkened.

If you think it's a gimmick then don't use it. I personally think it's a good idea. It easily combines the 1D and 1Ds lines and allows users to get that little extra reach if they need it for sports and wildlife photography if they want it. But can switch to FF mode to get wide angle shots or start doing portrait work with the same camera.

And I still think Canon could redesign the mirror motion to allow a EF-S lens to be mounted on a FF camera. But that is beside the point.
The "reach" is artificial. You are  using the same lens and same pixel density of the sensor. You do not gain any resolution or sharpness by "cropping". Nikon has been pulling back the mirror privot befor flipping the mirror up for a long time ( may be since F 4). The reason of doing that is to increase the size of the mirror to avoid  the dimming of the upper part of image in the view finder. They might still holding the pattern right on this.  As for using an EF-S lens on a FF is pointless. The image circle of the EF-S just cannot cover the FF.
I do agree with Macadameane that cropping in the camera may be a time saver. On the other hand, we can always use a longer lens or zoom out  a little bit instead of cropping.

For me, the 1.3X crop on a FF sensor is a gimmick. By switching from FF to 1.3X crop will not by us anything except a smaller file size and a narrower angle of view. We can do the same thing at post process by cropping the FF picture.

EOS Bodies / Re: 7D MK2 APS-H??
« on: April 04, 2011, 12:51:49 PM »
It will be great to see a 7D with APS-H sensor for the following reason:
1.The size of the body can be smaller than a FF body (compared to 5D II).
2. with the same MP, it will have lower pixel density than the APS-C and hence better low light performance and better dynamic range.
3. With 17-40mm lense, it will give us a 22mm equilvalent focal length. at the same time to avoid the bad optical result at the corner when used on FF.
4. The price will between  the 7D and The 5DII (hopefully)

Which isn't an issue with a reputable airline.


Have you  ever flown  a three letter airline started with 'S" that is based in northern Europe?? It spell out clearly as one peice of carry on with weight limit of 8 Kg. This airline is just as reputable as Lufthansa. Did you  check the web site of Lufthansa lately??? It also have the same limit without additional allowance for lap top or camera. You got through without problem may be due to: 1. you are lucky, 2. you did not fly recently. But we should not bet on our luck all the time.

Just want to point out that now some European airline limits the carry on weight to be 8 Kg (17.5 lbs).  The camera gear alone will be that much weight. There is no allowance left for lap top, power supply, external hard drive etc.  A bunch of high capacity CF card (or SD card) is the best way to go, reguardless  what camera system that you have.

EOS Bodies / Re: Canon Doesn't Need a Compact Camera System
« on: March 19, 2011, 07:09:27 PM »
IMO the most sensible thing to do would be to have an EF-S compatible system, similar to Sony NEX.

Canon would sell more EF-S lenses, and folks with DSLR bodies might be tempted to pick up a mirror-less body as an addition to the kit.

A mirror-less body coupled with plastic lenses like 18-55 would be pretty compact and light.

Now, Canon, let's please see some light EF-S primes!
The mgic word here is "compact  camera system". So in order for it to be compact, the camera needed to be a lot thinner than the existing EOS DSLR. Also due to thinner body, the lens can be made shorter  and  smaller.  Also the EF-S or EF lens mount is relatively big. That will also defeat the "compact"  purpose. So the new system needed to be with all new system lens to make it compact. However, an EF-S/EF lens adapter should be available for people that do not care about size and want to use the existing lens.

I can understand why  Canon is hesitate going into the "mirrorless"/ "EVIL" business. They have already have the G12 and S95 for the high end non-professional area. So the new "mirrorless" needs to be in the professional area (read it as expensive). Let us have a look in what most of the existing "mirrorless" models (except Leica M9)now. They  all have auto focus with about 0.3 to 0.5  second shutter focus delay ( same delay for most of the point and shoot). Now howmany professional will or can live with this kind of delay?? Leica M9 takes a totally differeent approach. IT uses manual focusing with built in range finder.So thes hutter delay will be less than 0.1 second. However. This will make the lens and body focusing mechanism to be very complicated. That is why the lens and body are so expensive. Also how many people nowadays knows how to or want to use a range finder for focusing?? Until Canon can come up with a fast auto focusing system based on "Live View", Canon will be hesitate to go into the high end morrorless business.

I agree with CR. I think Canon need to come up with TWO mirrorless camera that will complete with Leica M9 and the Fuji FX100. The first one is for pro's with the need for lens changing capablity and FF. The second one is for simplicity and smaller size with APS-C sensor.

EOS Bodies / Re: The 7d with an aps-h sensor!!!!!!!!
« on: March 07, 2011, 01:10:25 PM »
Olympus has an acceptable swivel screen, something akin would work for a7DII/5DIII.

Ad APS-H, mirrors and LV: how about dropping the rigid EF/EF-s seperation? Give the mirror also a powerless resting MLU-mode that retracts a locking pin that would prevent bad matching between modes and lenses. For the viewfinder a beam splitter that merges/switches between the images from the mirror and a display would be an option that also opens a door for lots of other uses. Or simply use just the rear display as a screen for EF-s lenses. With the 10-22 it wouldn't hurt and with the standard zooms we're at least close.
Bonus points for merging the AF sensors into the imaging sensor, thus allowing PDAF in LV and movie modes. :)
EF-S lens will not work right with APS-H sensor due the the image circle of the EF-S lens  is not large enough for the APS-H sensor.
