Post Processing / Re: My RAW Processing Workflow

What secrets are there for website color-management.  I assumed that sRGB should be the right output.  I'm not sure how to post an example of what I'm seeing.  I can say this... I know for certain that using Firefox or Chrome yields very different results than IE for viewing... with Firefox or Chrome being much more accurate than IE.  I might be seeing things, but I think that Firefox tends to show the images sharper too. 

Anyone have any thoughts on it?

Firefox is color profile aware, not sure about Chrome or IE.

I've been telling people the only thing holding me back was the lack of IBIS but...I didn't expect this feature to arrive so soon!  I'm still poor.  So I'll now amend that statement to: "I'll get a Sony AX series body when they have IBIS AND 4k video in-camera".

Sounds like the A7S Mark II is the camera for you? :)

Personally, I was waiting for A7R II with quiet shutter, faster frame rates, and non-lossy RAW files.  A smalish 35 mm f/2. lens like on RX1/R would have helped the cause greatly as well.

Lossless raw files would be perfect!

@Dilbert - Re the car analogy, fixes to minor issues is one thing. Adding IBIS to any camera body that didn't previously have it is another. The better car analogy would be if the same car from the same company went from 250hp in 2012 to 300hp (a la AF speed increase) with a newly developed 7 speed transmission (IBIS) for the exact same price as the previous year's model.

That sounds like a huge win for consumers.

IBIS for the record, is an astronomically large addition/development to the A7 body. It is the first IBIS in a full frame body which also makes it ground breaking. So it is by no means merely an incremental bump.

So what is there to be upset about?

While it may not be a problem for people that are new to the Sony market, it is a problem for people that are already a part of the market (i.e. already own a Sony rig). This is mainly due to the fact that they are presenting large jumps in tech for the same price in a short span of time. What this does is depreciate the value of what you had already purchased very recently.

In the business world, you depreciate assets very quickly - electronics goods typically are worth $0 after 3 years or there abouts. If you use a digital camera professionally and you aren't writing it off then get a better tax accountant. Same goes for computer equipment. If you've got a really good tax accountant then they can probably find a way to write it off for you anyway.

The argument "don't innovate too quickly lest it devalue what I bought" is an incredibly selfish and self centred perspective to take. You want Sony to design, build and manufacture cameras at a pace that makes *you* feel comfortable? What about the millions of other people that buy digital cameras every year and are more concerned with getting a good camera than what they can sell it for?

Of the millions of DSLRs that were sold in the last 12 months, what percentage would you like to estimate as having been resold online or elsewhere?

It also doesn't serve to create consumer satisfaction as many buyers will be discontent year over year once seeing that they paid the same price not too long ago for something that is nowhere near as good as the new one. Again, we are not talking incremental improvements. Consequently making me uneasy about holding onto any Sony body for too long.

Aren't you assuming that everyone else believes the same as you here, without asking them?

I'm willing to bet that most buyers will keep their cameras and won't care if a newer model is released "next year" or the year after because their camera will keep taking pictures.

Quote
But just speaking from my vantage point, anticipation of devaluation and the presentation of something much better pushed me to get rid of the A7r rig I had quickly as I didn't want to be left with it once the mark 2 came out months later. I had realized I wasn't completely happy with it and just pulled the trigger on getting rid of it (much like a hot potato). Otherwise, I probably would have played with it for a few more months.

Good for you! You recognised that you'd bought something that you didn't need/want and sold it.

Why would you be pissed?
Because the manufacturer improved the way a feature worked and released an updated model?
How can you be angry with them for that?

A. If it were merely the AF speed improvement and nothing else, this could be done in firmware as Sony themselves have stated that it is a result of a change in algorithm. Fuji improves AF speed via firmware even in previous generations of the same cam.
B. In this case, I would moreso be angry with them for the IBIS specifically.


Are you upset with Sony because they bring out new features?
Or are you upset with Sony because the rate of their improvements would leave you feeling poor (or that you don't earn the salary that you want in order to keep up with them) rather than feeling rich?

A change in AF speed through a new algorithm may depend on there being a newer processor in the camera or something else. Or it may simply be that why should they spend money on updating obsolete/released products when they can spend money developing for new products to capture new markets?

Consider that from a release engineering perspective, it may be simpler, faster and more cost effective for Sony to release a whole new camera with a new AF algorithm than to update it for an existing camera.

If your current whatever does what you need then why do you need the latest?

As I have stated, I am a gear whore. But in this case, the jump from A7 mark 1 to 2 is a leap. A leap which provides features that I would love and need.

Do you update your computer every year?

No, but this is apples and oranges. If there were a technological leap year over year, the answer would be yes. But the fact of the matter is, anyone who knows anything about computers knows that they merely bleed out the 10% bump in performance every year which with current tech doesn't really help me much until I get to about the 3 or 4 year mark.

Computers have been through that part already. To some extent, we are now in a plateau however I will refer you to Moore's Law:

Do you get a new car every year?

If it only cost me a few thousand dollars and was a leap from the previous car I had, yes. But again, apples and oranges as there are many variables that differ with car purchases.

But consider that with each year, there is always something new or fixed when compared to last year's model, even if they are both 90%+ the same. If you go to buy a new car in 2014, you don't buy a new 2012 car, rather (or more likely) you buy the 2012 car with whatever new updates have gone into it over the last two years.

Very true. And I learned to accept that a long time ago e.g. computers. But that doesn't apply here since the leap from year to year in the A7 has yielded significant changes.

If you're afraid of rapid change then you might be waiting 5 to 10 years more for digital cameras to "settle down".

...
Put it this way. Had I bought the A7 at any point since it was released, I'd be pissed right now as two of the main changes/additions/features are very significant to me. There is nothing that would lead me to believe that if I allowed myself to get sucked in again that we won't be having this conversation on November 20, 2015 again. Except at that point, I would actually have the burden of trying to get rid of a Sony body.

Why would you be pissed?
Because the manufacturer improved the way a feature worked and released an updated model?
How can you be angry with them for that?
Because they didn't put it in the model/version that you bought?
There are limitations as to what a company can develop and deliver in any given period of time for a new product. The same is true for Canon.

To pick a simple example, if you bought a 5D Mark II when it first came out, how long did you have to wait for the 5D Mark III in order to get the in-camera leveling tool? With Canon, this problem is worse because you wait twice as long for the same quantity of updates.

No product is perfect, so why be angry with a manufacturer for releasing a better product of the one that they already sell?

Nobody would be forcing you to sell...

Yeah...its impressive..yes...Canon is sound asleep...but I still can't get from a sony what I can get image-wise with my 5DIII with my Sigma 50mm f/1.4, Canon 85mm f/1.2 etc......from the standpoint of low DOF ...etc....Sony just doesn't have the wide f-stop lenses with AF....but man...that body just keeps getting sweeter and sweeter.  Canon....WAKE UP!

So far as I know, the Sigma 50/1.4 Art Sony A mount version is available for pre-order:

Also, am I going to have to look at trying to upgrade my outdated camera body every year? The last thing I anticipated was a mark II of any of the A7 line this quickly. I would hate to look at my camera body like my iPhone (although I'm sure this is exactly what Sony is hoping for).

If your current whatever does what you need then why do you need the latest?

Do you update your computer every year?

Do you get a new car every year?

When it comes to anything "hi-tech", products are generally obsolete the minute that they go on sale because there is already newer technology being developed and on the way to becoming a newer version of said products already.

Slow and finicky definitely sums up a lot of my feelings about it. The handling and UI just don't do it for me along with a few other issues. If any of the a7x bodies handled like my X-T1, I would be much more inclined to give it another go. That, and I would need them to add a 35/1.4 to their ecosystem. As it stands, they have nothing that remotely covers my needs except for the 55 (which is still not exactly what I want).

Does anyone know whether the newer A7S is slow and finicky too?  For some reason, Sony wants a lot more money for the A7S than for the A7 or A7R.  Does this mean it's speedier and better in operation?

Sony wants more money for the A7S for one reason: 4K

And the reason they can do that is that currently 4K is a premium video feature that people will pay more for.

EOS Bodies / Re: A Real EOS M Replacement Coming Soon? [CR1]
« on: November 19, 2014, 07:29:02 AM »
The biggest criticism of the M has been AF performance in comparison to other mirrorless cameras that can rival conventional PDAF DSLRs.

Seems reasonable to me to assume that PDAF that is sensor based and found in more recent Canon DSLRs would also be found in any newer EOS-M - with perhaps even better algorithms behind it to deliver better AF than prior MILC cameras.

EOS Bodies / Re: Canon 7D II sensor measurement
« on: November 18, 2014, 10:25:40 PM »
The best page on the 7D Mark II sensor comes from sensorgen.info:
http://sensorgen.info/CanonEOS-7D-Mark-II.html

It is clear from this that Canon still hasn't resolved the high read noise at ISO 100 - 800.

Third Party Manufacturers / Re: New Sigma Lenses Coming Q1 of 2015 [CR1]
« on: November 18, 2014, 10:02:08 PM »
Sigma won't tell about 85Art, who gonna buy 85/1.4 from then, when we have a confirmation of a newer version coming?

I wonder if Sigma are delaying the 85 Art whilst they try and resolve AF issues?
