The changing field of professional cameras

[skieur]

^^ have you ever read an outright negative review in Popular Photography? Reading that magazine you'd think every camera was as good as any other.

Read the reviews carefully and pay more attention to the lab results and yes I have seen some negative evaluations of several cameras and models. For some it may be hidden in the paragraph or two at the end on similar cameras which may be suggested as better choices.

Ok. I looked at the sample images for the a77.

Skieur. You're *officially* on crack. Those samples are noisy as all hell.

Dumb statement! Be specific! What are you talking about? Where in the image? How does it compare with the Nikon and Canon images?

General statements such as the one you made above are NOT CREDIBLE. Try and show me that you actually viewed the images and can talk knowledgeable about them as a pro. Otherwise.....I am not likely to take such emotional statements seriously.

Limited view of technology, eh? The EVF on the Sony A77 reduces vibration from the mirror producing greater sharpness, increases speed which permits new features such as in camera panorama, tilt-shift, and HDR, as well as better HD video, and produces a what you see is what you get image in exposure.
With all thoses pluses, it is an obvious direction to go.

Well your 'views' are certainly one sided... for instance, you've failed to acknowledge that the mirror introduces 1/2 stop loss of light all the time. I'll take faster shutter speed advantage over the miniscule mirror vibration any day.

"Sony has unveiled the SLT A55 and SLT A33, the first pair of cameras to incorporate the company's translucent mirror design. The Single Lens Translucent (SLT) cameras offer live view with full-time fast phase-detection AF whether in stills or movie shooting. This is achieved by having a fixed, semi-transparent mirror that redirects a small amount of light onto the AF sensor while allowing the rest through onto the main imaging sensor. "

No mention of a 1/2 stop loss of light here and it is definitely not from a Sony biased web site.

Skieur,
Perhaps you should check this out... http://thesybersite.com/sony/a55/index.htm#slt_mirror_image_quality

An independent test performed by an owner of an A55. He tests and confirms 1/2 stop (30%) light loss from the mirror and what he calls 5% degradation in image quality due to the extra piece of glass (mirror) always present. ENJOY!

Really, man? This coming from YOU?!

But. I'll play your little game for now. Yes. In the mid shadows there is significant noise which is more pronounced in the out of focus areas (where you'd expect it), especially compared against the aforementioned Nikon and Canon bodies, though the Canon example did not use the same reference image.

However, being that the example on the Nikon example was not focussed properly, I have some doubts about the reputability of this website.

these are done at ISO 200!

And what method did he use to calculate 5% from, anyway?

It has already been indicated that Sony has made a deal with Nikon for selling them the 36mp sensor and that a Nikon D800 will come out in February 2012. Sony in turn will come out with an A77 36 mp camera in April. I know all about sensor sizes but multiple sensors and blending high speed shots reduce picture noise too. Sony, Nikon or Canon 36 mp sensor will not kill medium format digital, but it will certainly squeeze the lower end of that market. Pros have noted that the medium format market is not as large as the one for digital single lens reflex cameras in the first place and that it will continue to decline.

Pretty funny, since you have done exactly the same thing.:lmao:

Maybe you should write out all your posts as just 'skieur'?? They would be more interesting! Perhaps?

Classifying the A77 as a Pro level Camera is a slippery slope at best. Granted, it does have some neat pro features and there are I'm sure some professional photographers who are happy with the A77. What about the Nikon D7000? Is it a pro camera?

Well your above link seems to be as clear as mud. Read the following:

What is NOT purple fringing? Well, any sort of similar phenomenon that is caused only by a lens, and that would also appear when that lens is used on a film camera. Traditionally understood and defined chromatic aberrations (CA) are NOT purple fringing; but purple fringing does often appear to be related to the presence of CA in a lens. So a lens with inherent CA may also be likely to produce purple fringing under the right (wrong?) conditions with a digital camera.
​

Irrespective of trying to make out, what he is actually saying, you seem to forget that the A55 consumer model is 2 models below the A77, so the comments do NOT apply.

There is for example; NO ghosting, NO chromatic aberations, No purple fringing etc. on the A77. The OLED viewfinder on the A77 is NEW with greater resolution, brightness, and contrast than the one on the A55. The viewfinder is larger as well. It is also better in lower light in the studio. The introduction of the electronic first curtain shutter has also made the A77 much faster and more responsive than the A55. The lengthy writing times for burst shooting to the card that was present with the A55 are also no longer the case with the A77 either.

What you were seeing was lack of resolution from the Nikon example. It had NOTHING to do with focusing which is obvious from looking at the photo. By the way, the Canon does have the SAME test image, but then perhaps you read my directions as carefully as you have read other posts in this thread.

Boy, you display MINIMAL experience with photography and looking at images. The fact that you indicated in another forum that you don't really even understand the Sony SLT viewfinder but are apparently against it anyway, shows that your opinion has limited value.

Once upon a time the ultimate pro camera was the K Brownie. So, yes, cameras have evolved. WOW.

Just another one of your mindless, whatever-you-are-looking-for thread.

Skieur, you're a joke. Go back to your shell!

 

[unpopular]

So, then the resolution is varied according to relative depth?

Skieur - you make such an enormous mess out your arguments it's harder to detangle what you're talking about than it is to rebut.

To keep it simple, the Nikon image is just not as sharp as the Sony or Canon.

The Sony is not marketed as a pro camera, it's listed as being more in the enthusiast/semi-pro line. It's build is nowhere near the solid quality of either the Nikon or the Canons you are trying to compare them to. Take that Sony out in one rainstorm and you may soon notice why the others are "Pro" cameras with their weather resistant sealing. If you put photos side by side from these cameras ...

Most pro cameras have mirror lockup, and anything moving so slowly that you'd need this feature you wouldn't need live view, so really this is a non-issue.

camera panorama, tilt-shift, and HDR, as well as better HD video, and produces a what you see is what you get image in exposure.

Ok, well. You got me there. Silly toy features like these can't be done in camera with a traditional SLR. So if you want cruddy 8-bit panoramas, goofy, fake tilt-shift effects on cruddy 8-bit images and limited HDR functionality in-camera because you're too lazy to actually make a proper HDR then you'll definitely want an SLT - or a mirrorless interchangeable that has all these features except for the pellicle which permits slightly faster AF at the expense of signal.

Definitely, inherently foregoing image quality for toy features and faster AF is

an obvious direction to go.

right?

Well, if you are a pro, you must be a starving one, since your silly toy features save time and will help me make more money.
