Lenses / Re: Ken Rockwell reviews canon 50mm f/1.0
« on: November 22, 2013, 03:20:46 PM »
I finally have to ask since I've seen a lot of hate here for Ken Rockwell - can somebody please explain why this is?

Because he had been trolling around for years tossing out bizarre mini-blogs to make controversy and grab traffic and then got tons of traffic and then became labelled the go to camera expert on the net despite having so much nonsense mixed in all over his site and many of the more beginning photographers he was trying to attract wouldn't have a clue as what parts of his website were good and what parts were nonsense passed off as wisdom or the truth.

SO…. why are people still reading his blog? If he keeps getting brought up as a voice then we are to blame for perpetuating the problem.

literally it is a great great lens , almost perfect , no doubt about it.
but it is just too huge , it is longer than the Nikon 24-70mmf2.8G, I think  the size makes it just an impractical lens for many.
I do not mind 4k for a lens of this great, but I do really hate the huge long ugly barrel design.
So I will use my Zeiss 50mm f2 MP for another few years.
if you guys do not mind the huge 50 kind of lens , then just get it , there is nothing comes close to it at least in a lab test.

Ultimate IQ was the goal, not a pancake.

Honest question.  I don't get why a well made lens with half dozen machine ground lenses of a particular shape and in one configuration can cost 10-20x what another well made lens with a half dozen machine ground lenses of a similar shape and configuration?  How can the shape of a lens element or the coating cost so much more to produce?  What is special about this lens that Canon, Nikon or Sigma could not reverse engineer (i.e. lens shape) and produce for $400?

It is only slightly about materials and labor.
This is a prestige brand. It is the Rolex of lenses. They are thoroughly aware that the market for manual focus lenses is small so the ones on sale must either be ultra premium (Zeiss, Leica,Schneider etc) or super cheap (Samyang).
By leaving off AF they obviate the need to license, design, and test a configuration for both Nikon and Canon and the attendant support and repair expenses of all of this.
By imbuing the lens with the last bit of resolution, bokeh quality and superb build, they can maximize their profit over a small production run. By dropping the price they lose the cachet of scarcity and the mythic  legend of its alleged excellence.
Familiarity breeds contempt. Scarcity and urban legend breed awe.

I use PWs exclusively for their reliability.

The only thing that I am unhappy with is the lack of a metal foot. I like the locking feature but even with care the feet break occasionally. The Yongnuo triggers do have metal feet but no lock so are not what I want.

as from a technical standpoint I do not see how an EVF will ever even be as good as an OVF, let alone superior to one. Personally, I am hoping the classic slap-happy, noisy DSLR lasts for another 50 years...after which point I'll probably be dead, and will no longer care.  :P ;D
I agree that for the applications you cite an EVF would not be the solution. However I think that we are not likely to see the abandonment of EVFs but rather further improvement.
Perfection is not really necessary to be able to achieve 98% of what a photographer needs to know before pressing the shutter.
I have been photographing a series of jobs over the last week where I dearly would have loved to pre-chimp my shots.
I was in a variety of fast moving situations with varying light brightness and color temp that necessitated rapid shooting and chimping to ensure that the exposure was ok.For the most part I was doing well but I would have realized a whole lot less PP had I gotten closer in camera.

I acknowledge the shortcomings but like RF finders, EVFs have their uses.

Lenses / Re: The 24-105 and/or the 24-70 II ...

Another vote for the 24-105.

I am often at the 105 length. I am also often in low light situations shooting candid groups.
I used to think that f4 was a real drawback but I found that even at f4 the DOF was insufficient for good images of multiple subjects.

F 2.8 would help with focus and image isolation but as that is not the goal of my work I can pass on it.
Available darkness needs high ISO and a still camera.

I do a lot hand held but I also use it on a tripod where I get extremely sharp results.
I am happy about the price drops as it allows me to get a great price on a backup of this critical tool.

Got it today.
A few quick tests in the studio reveal that my copy is plenty sharp but the real challenge is accurate focus.
Ironically using Live View on a camera stand was not a sharp as guessing at the focus while hand held.

Also, I noticed that the exposure through LV is not at all accurate even though the camera is set to exposure simulation.

Small bother as I plan on being on the tripod anyway.

While the camera really seems to annoy some here, I am sure it will attract a fair amount of interest but the price may put off a few.
The real issue here is Nikon is trying to cash in on the retro craze that is not just limited to cameras. They just may be overplaying their hand and hoping to collect the funds of hobbyists they hear on the internet bemoaning the loss of simplicity and directness of old style SLRs.
Sadly, they were not listening to their comments indicating how cheap they were.

Just ordered one this morning. I notice the price walks around a bit but I was happy to get it for $339.
I had thought about the Canon 14 but the performance is underwhelming for the money.
I am planning on using for architecture. (Yeah, I head all the criticism about the distortion). I am not too worried about that and if it happens o fall short on that it should sit be great for landscape.

HDD are generally pretty difficult to kill with magnets. You need it either seriously close (in contact with the disk, in which case it's dead from the scraping anyway) or seriously powerful. There's a reason de-gaussers that will kill a HDD are floor/desk standing.

You mean that Walt and Jesse's magnet idea in "Breaking Bad" wouldn't work? It was on TV it must be true. ;)

Sony's SLT is very different from the Canon film pellicle mirror cameras.

Canon had a semi-translucent mirror to direct half the light to a viewfinder, and the other half to the film - the upshot is no mirror slap, so higher frame rates are possible and also a more stable camera, and also no viewfinder blackout. The downsides are a darker viewfinder and less light hitting the film.

Sony use the same type of mirror to redirect half the light to a dedicated AF chip, and the other half to the sensor - there is no OVF. So its basically a mirrorless camera in a big body and only half the light sensitivity it should have. A mirrorless camera with on-chip PDAF is much more sensible if you're going to dispense with the OVF - which is precisely what the A7 and A7r are all about.

This new Canon patent is almost a digital version of the film based Canon pellicle mirrored cameras, but with one major difference - the mirror has variable reflectance/transmission. If it could approach 100% reflection while composing, you've got pretty much a conventional bright viewfinder, and if it could electronically switch almost instantly to almost 100% transmission, pretty much all the light can hit the sensor for the shot.

Much higher frame rates, much shorter shutter lag, and no vibration due to mirror slap could be on the cards.

IIRC Sony claims only a 1/3 stop of light lost by the mirror. Apparently only a enough light to work the PDAF. The bigger issue for some was the ghosting and random artifacts that occur in some lighting situations.

Maybe its harder to make a 24-105 than it looks. ;)

Ever since English has been spoken and written people have been complaining about its misuse.
I used to be one of those people but I yield to the understanding that it WILL change whether I like it or not.

Just think how much it has changed since Lincoln wrote the Gettysburg Address. The people of that day would be both amazed and despairing of how the language had changed. Not to mention being astonished that we wasted time taking pictures of our food and our cats.

EOS Bodies - For Stills / Re: High Megapixel DLSR a niche market?
« on: October 26, 2013, 11:09:09 AM »

It's niche in term of how many cameras Canon will sell, and how much profit Canon will make from it.

Absolutely correct. Canon has a huge line that has a ton of sales volume.
Canon got sidetracked in the MP race a while ago precisely because the were responding to their customer demands for better video and low light performance. Nikon continued chasing the MP numbers because they did not sense a cost -effective battle in the video arena.

The manufacturers only chase so many rabbits.
