Lenses / Re: Review: Sensor Performance of the 7D Mark II
« on: December 03, 2014, 11:53:06 AM »
as far as DP-AF is concerned ... so far Canon has not been able to turn that feature into any really tangible benefiot for users. To the best of ma knowledge, both 70 as well as 7D II  are still rather on the slow end of the bunch when it comes to autofocussing in Live View. Nowhere near where a Sony A6000 or Fuji XT-1 are.

I am asking myself, whether there is real value in DP-AF technology and Canon just not able and/or willing to unleash t, or whether its basically a "dud innovation".

I have both the X-T1 and 70D. The 70D is not slow comparatively. It is actually just about as fast as far as when they both lock on. The issue for me with the Fuji is that it hunts when you don't expect it to. Same with the A7r when I had it (for what it's worth). DPAF has been much more reliable in my experiences with both cameras in various lighting situations. Comparing DPAF to any mirrorless camera I've had, it is much more consistent and reliable while being competitively fast.

Canon General / Re: Does Canon really deserve this?
« on: November 24, 2014, 07:16:51 PM »
As far as the claim that Canon has already "lost" in the mirrorless market, I don't think that that is the proper perspective to view it from.

First, they only half-heartedly entered the market to begin with which wasn't really an attempt at winning any type of battle. Second, they already possess the sensor and other technologies to make a worthwhile mirrorless body e.g. use the existing EOS M with a dual pixel sensor. Third, the ecosystem is the ecosystem. Nothing changes with regard to everything else that Canon has to offer in conjunction with any camera body they release.

Those few things alone would make it much easier for Canon to simply release another M with a few simple upgrades they are already capable of and take a decent chunk of the mirrorless market. This doesn't even really require that they break a sweat.

Now imagine if they actually threw some additional innovative features into it. Point is, it wouldn't take a whole lot to get back into the battle (assuming they ever lost it).

Third Party Manufacturers / Sony - Question of a Differing Variety
« on: November 21, 2014, 12:45:58 PM »
Anyone happen to have a technical answer for why there isn't an EF to FE mount smart adapter that allows for usable autofocus speed and accuracy?

The reason I ask is because I own a Zeiss Contax N mount 50/1.4 that has been modded by Conurus (one of the main players at Metabones) which autofocuses very well on all my Canon bodies. This would lead me to believe that Conurus is significantly tapped into the Canon AF protocols somehow. However, every generation of the Metabones smart adapters for EF to FE so far have not been up to par with speed and accuracy of AF.

Second question is, anyone think that it might be easier to accomplish with the A mount bodies?

Hoping someone here has an explanation for this.

If it were possible at some point to get usable performance with adapted EF lenses, I think full transitions into the Sony ecosystem would be much more painless especially with some of the new features being offered in the latest body announcements.

However the X100 sync is a work a round that has it's own limitations, anything short of a true shutterless sensor read exposure and very short flash duration is. The real game changer in this area for serious pros has not been the X100 but the Profoto B1 Air kit, sync at any speed and any aperture, true HSS with a decent amount of power.

And now the Chinese are coming out with their own versions of powerful HSS enabled integrated battery powered studio strobe crossovers at a fraction the price, that is where the strobists that want to push boundaries should be looking, not at leaf shutter hacks.

Very good point regarding what the best option for strobists may be. There are definitely limitations even with the x100 setup. However, the kit you're referring to starts at just shy of  $4,000. I would love to have it. But for mere mortals like myself, a used x100 runs about 400-600 bucks nowadays (x100s for 800-950).

Haven't read anything about the chinese knockoff versions. But you definitely have my interest piqued. Although I don't know what price range they would fall into as even 25-50% of the cost of the name brand kit would be too expensive more many.

BTW, can you point me in the right direction with some names of the knockoffs? Thanks in advance.

The RoveLight RL600 has a fully integrated battery for $599, more than 8 times the power of a 600-EX-RT, and that includes the radio trigger with power control.

Thanks for the info. Was digging around and saw that they had the flashpoint mount version for 379 on sale right now but read that the bowen mount version was preferable for it's universal compatibility. Almost pulled the trigger....lol.

Also for the record, regardless of whether we call the x100 a work around, hack, etc, it still works pretty damn well. :)

@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. 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.

I may be way off on this theory as I do not know the mass market personally. 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.

To me, it just feels like Sony is hitting the market with a barrage of varying products essentially throwing tons of stuff against the wall to see what sticks. That, at least for me is definitely not confidence building.

I think the SLT-A99 also had IBIS.  But the a7 is the first with this 5 axis IBIS though

You're absolutely correct. My mistake. I was too quick to parrot an annoucement I read re the A72.

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.


Because they didn't put it in the model/version that you bought?
See above
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...

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.

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.

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.

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.

Quote from: AcutancePhotography link=topic=23769.msg465160#msg465160
I applaud your honestly.  LoL  Bottom line is that is the way many of us really feel deep down.  We just don't always have the guts to confess.   ;D

LOL. I'd say that is one of the elephants in the room when it comes to a forum about anything that involves tech, rumors, and development.

In this case though, the IBIS and the claimed improvement in AF speed are huge advancements for my needs. So while it simultaneously scratches the gear head itch of mine, it is something I actually would have great use for.

BTW, I say claimed AF speed as I have learned way too many times as of late that all these mirrorless companies love to claim the same thing since they know it is a big knock on the body type. "25% faster," "30% faster," "Fastest AF to date," "Fastest in the market." That all means nothing to me at this point. Show me accuracy and speed in all the lighting conditions people actually shoot in and I'll start sipping the kool-aid. But until then, all I have to say is that all those proclamations have been nothing more than headline/attention grabbers.

That's pretty much where I am. Wanted to take gear on a motorcycle trip, so I got an a7r. Although the 55mm is quite good, I find the camera to be slow, and very finicky. The 35mm is OK (but I had to glue the sun shade back together after it separated for no good reason). The telephoto zoom was only the second lens that I have ever returned in my life. IMHO not great at many apertures, and far too many speeds. I'd like to see if Sony can improve it, but I see no reason to dump my Canon gear which is good for almost everything, if heavier. Now I wonder if I should get a 5D III to go with the 1Dx, or wait for a new full frame.

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).

14
Also, am I going to have to look at trying to upgrade my outdated camera body every year?

Why would you upgrade if your current model does what you need it to do?

Just because a new model comes out does not make the previous model "out dated".  Of course that is what the camera manufacturers want you to believe.  ;)

Because there is a good portion of me that is a gear head/gear snob/whore for technological advancement that I don't do a very good job of ignoring all the time.  ;D

That same question could be asked of most of the things that I have upgraded/replaced over the years. Why would I? Because I can, want to, and inherently need to since I am aware that there is something better. lol.

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.

I've already tried the A7r + 55/1.8 + adapted lenses experiment for a few months and decided I just didn't care for the whole setup. It had/has some advantages. But the disadvantages and frustrations I had outweighed the positives which has led the rig out of my door.

That being said, the A7II is really intriguing with the updated AF and IBIS. My interest is piqued once again.

My only issue is the same one others have expressed already....how much commitment is there going to be from Sony to all these systems? 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).
