Yes but to really take it over the top why not play with wide angle perspective at the same time.

Lenses / Re: Canon EF 70-200 f2.8L IS II pricing and feedback
« on: September 29, 2014, 08:01:57 PM »
I picked $1799.00 that seems reasonable.  But, lets face it if amazon has it for $1599 I might not be able to stop my self.  ;)

EOS Bodies / Re: mirrorless ?
« on: September 29, 2014, 09:20:35 AM »
I was mostly looking to reduce weight.  It is also nice to use old manual glass.  I prefer the ergonomics of the Nex6 and A6000 over the EOS-M.  It is mostly because of the battery bump and two control dials.  Two dials are needed to change shutter and

On a Sony you can zoom and use focus peeking at the same time.  Which ML cannot do. 

If Canon released a serious mirrorless camera that has electronic viewfinder, focus peeking, and two control nobs and a few more settable manual buttons and showed serious commitment to mirrorless I would be torn.  I do not yet have much invested in Sony lenses. It would not take much to switch to Canon Mirrorless.   

But if 6 months that will be a different story but I will be a hard sell I like the way Sony is going with its current mirrorless cameras.

The current EOS-M is a interchangeable lens point-and-shoot.  I was looking for something more.

I'm a wildlife photographer and shoot "wild" wildlife. No zoos or captive animals. I've spooked many animals with the should of the mirror slapping even on silent mode. I'd love a truly silent operating camera.... However I also would like an OVF.

There is still a shutter in many of the mirrorless cameras.  My Nex6 is louder than my 6D.  So you also need some type of fully electronic shutter to get silent shooting.

EOS Bodies - For Stills / Re: Why haven't you left canon?
« on: September 27, 2014, 10:58:58 AM »
I bought into Canon because of the Lens and camera ergonomics.  Where Nikon and Sony have comparable lens the offer less performance and higher cost.  If they have a comparable lens. 

As it stands I am halfway out of Canon.  I will be keeping Canon for wildlife and outdoor photography.  I also bought a 6D for low light use.  Family events and other such things.  But I am moving to mirrorless for everything else.  I have not bough much camera gear this year I have been saving up for some lenses. 

I was going to buy an Sony A7r but decided it would be ridiculous to spend that much money and not have a single native full frame lens.  I have a full set of manual focus primes to use when I do get one.   

My next purchases will all be lenses. 
  • Tamron 150-600 VC
  • Sony 24-70mm F4 Vario-Tessar T* FE OSS
  • Sony FE 70-200mm F4 G OSS

Likely in that I also need a good Full frame wide angle zoom.  It is going to take some time so the Alpha 7r II will likely be out before I am ready to buy a new camera.

I will likely be gone before Canon announces any real mirrorless.  Canon would need to announce a mirrorless pro line of cameras.  Something along the lines of a OMD-EM5, Fujifilm X-T1 or Sony A7 camera system with pro level lens to make me consider staying. 

That said it will be 10-15 years before mirrorless can replace what I plan on using my Canon DSLR for.  So I will be here for a while and I love Canon lenses.

Looks like the a7r will be your landscape cam. Now you can shorten your posts to a link to this thread when the issue rises.

As for Lee jay, I would say a bounce flash.

Yes, as should be quite obvious, a flash is often a great way to control scene contrast.  That was a 550EX fired into the ceiling.

You do realize the whole point was to demonstrate DR, right? Oh, and um...I don't have a flash for the A7r...so, doing a comparison with flash just wasn't an option.

Do you have a flash for your Canon or Nikon cameras?  If so you can use one of those flashes in manual mode.   I use my 430Ex  II on my NEX 6 quite often.

Photography Technique / Re: Why 3:2 aspect ratio?
« on: September 26, 2014, 03:22:16 PM »
This conversation brings up a question I have had for a while. Why not have a square or a cross shaped sensor?

Let me explain. Say you are camping near a lake. First you take a picture of the lake during a sunrise. You set the camera to landscape at 16:9, or whatever you want, and only the pixels in that ratio is used in taking the shot. Next your child wakes up and is sticking her head out the tent door. So you switch to portrait 4:5 and you can hold the camera in the same comfortable position as you do in landscape and take the picture. The day goes on with different shots with different ratios.

Obviously this would only work with a mirrorless camera and you could not have a lens hood with pedals.

I think some of the advantages would be you get to hold the camera "normally" for portrait shots, you only use the pixels you want (thus keeping the size of files to a minimum), there is less cropping in post, etc.

What do you all think? Stupid idea or does it have some merit?

I would rather crop in post instead of doing all of the adjustment while taking the pictures.  You can already change the aspect ratio in the camera if you wish and use Live View.  But I have never really seen the point.  It is fairly quick to crop in post.  A square shaped sensor could be interesting but there is no reason for a cross shape sensor just turn you camera.

EOS Bodies / Re: Canon Says Higher Resolution Sensors Are Coming Soon
« on: September 26, 2014, 02:37:27 PM »
The 50mp sensor is medium format and Sony does not have a medium format camera system.  They have worked with  Hassleblad before.  I think the state of Hassleblad financially was what lead to Pentax and PhaseOne also getting the sensor.  The D800/D800E/D810 are Nikon and it has been proven time and time again that Nikon adds proprietary processing before  writing data to the "RAW" file.

This is actually true of Canon now as well. DIGIC 6 processes the data before writing it to the RAW file. The 7D II will probably be fairly impressive at ISO 16000 for an APS-C camera. It'll be impressive because the data written won't really be truly "RAW"...it'll be cooked, just like a Nikon camera. The other thing Nikon does is clip blacks, instead of setting a bias offset. That tends to result in cleaner shadows, but it's discarding a little bit of data that could be useful in certain circumstances (such as astrophotography...which is the reason a hack was created to remove the black point clip and restore the bias offset, as it restores the linearity of the signal in Nikon cameras.)

For what it's worth, the A7s, a powerhouse at high ISO, also cooks the raw data. The BoinzX chip is very similar to the DIGIC 6 (I honestly don't know which has the superior design or approach...we'll have to see.) It too does noise reduction on the RAW data before writing it out to the file.

Cooking the RAW is probably going to be a standard practice now. Even if you reduce read noise, at high ISO, IQ is ultimately going to be photon shot noise limited. You can increase Q.E., but the high end sensors like the one in the A7s are already at 67%. There is maybe a third of a stop of "real" improvement to be made in the sensor itself by increasing Q.E. to 100% (which is doable, but expensive...at least currently...it may become cost effective at some point in the future.) Any other gains are going to have to be made either by increasing the sensor area (i.e. medium format sensor), or by processing the RAW data. For established camera systems, increasing the sensor size isn't an option...hence the reason everyone is cooking their RAWs now.

I did not mean to imply that Sony did not precook their RAW files.  Only that Pentax and Nikon are better a precooking their RAW files.

EOS Bodies / Re: Poll: Would you buy a high MP Canon EOS 5DIV?
« on: September 26, 2014, 02:26:29 PM »
I more than likely could not justify the cost of a high MP Canon EOS 5DIV.   

I remember a conversation when the D800 came out.  An event shooter was complaining about the D800 having to much MP.  Most of his customers did not want huge prints they wanted pictures for Facebook and such nonsense.  The huge Raw images were slowing down his workflow.  He was a life long Nikon shooter contemplating buying a 5D III.  I do not know what ever happens with that but not everyone needs a high MP camera.   And not everyone needs the auto-focus system of the 5D III. 

I would rather see them keep the 5DIV an event camera and make a separate High MP camera in the same body size or smaller.  A smaller camera is not needed for studio work but could be very useful in landscape photography were hiking is involved.

EOS Bodies / Re: More Talk of an October Announcement of a DSLR [CR1]
« on: September 26, 2014, 02:13:50 PM »
To all the people threatening to jump from Canon to Sony/Nikon...

When you bought your Canon camera, it was obviously because you needed/wanted its performance.  It was good enough.  Now suddenly it's not good enough?  Did it deteriorate in quality?  You bought a camera because its performance was what sought, and now its performance (which is the exact same as when you bought it) is not good enough?  Y'all make me laugh.  Hah.

Not thinking about it I jumped to Sony mirror-less when the EOS M was announced.   Bought a meta-bones adapter. 

When I bought into the Canon system I did it for the lenses.  After researching both Canon and Nikon, Canon was the clear winner for my main photography interests.  At the time the sensors quality was basically the same.   For the lens I was interested in Canon had better and cheaper options.  So I bought the cheapest Rebel out at the time and started building up my lenses.  The primary goal was to go full frame and enjoy taking pictures at the same time. 

For macro and wildlife Canon makes allot of sense.  That was what drew me to Canon.  But I take pictures of everything else as well.  I was happy for a while.

When the EOS M was announced I was seriously pissed off.  I wanted, needed a new camera my 60D had recently taken a bath as was trashed.  I was looking for a good mirrorless and a possible camera to hold me over until the 70D was released.   Without a view finder it would not meet either of those needs.  So I ordered another 60D.  Then ordered a Nex 5N for my parents but planed on taking it for a test drive. 

I was very impressed with the Nex 5N image quality so I pre-ordered a NEX 6. 

Then a funny thing then happened.  All of a sudden I could not stand looking at the 60D files with anything over ISO 800.  The truth is even ISO 400 is quite bad compered to a NEX 6 at ISO 400.  I was never quite satisfied by high ISO performance but the difference was eye opening.

So no the performance of the Camera did not degrade my expectations changed.   

I am very happy with the high ISO performance of my Canon 6D.  But at low ISO a Nex 6 is nearly as good. 

Canon needs to do two thing, release a high MP camera and improve ISO their crop camera offings.  The 7D II may improve the ISO performance.  I am with holding judgement. 

The truth is I am more likely to buy a Sony Alpha 7r successor then a high MP 1D series or 5D series camera because of cost and physical size.  Quite frankly I would have bought a 7r already if it had a first curtain electronic shutter.

I am not satisfied by the rate of Canon's sensor improvement.  The way I see it the 70D II was a year late.  The 7D II is two years late.   A high MP camera is 3 years late. 

Every year my expectations for what a camera should do increase.  And every year Canon falls further and further behind. 

But unless Nikon changes its ergonomics and there lenses get cheaper I will continue using my Canon cameras for wildlife and macro.  But for my general photography needs I may buy into the full frame E mount and a Alpha 7.

Canon's G7x sensor is from the original RX100 or the RX100 mk II, not the same as in the RX100 mk III

Do you have a link to prove this?

Also, according to DXOMark, the RX100 Mk 1, 2 and 3 sensors are nearly identical in performance with Mk 1 only being very slightly behind for low light ISO.

Two things:

1.  The RX100 mk III is 20.1 MP, mk I and mk II are 20.2 MP as is the Canon G7x

2.  DP Review interviewed Sony rep who confirmed that Sony does not sell their most current sensors to anyone, but keeps it for their own cameras. Sony sells only the sensors that no longer have unique value.

I don't know about 1, but 2 is patently false. The D800/D800E/D810 has been demonstrably "better" than the Sony A7R and where is the Sony 50mp camera that is currently sold by Pentax, Hassleblad and PhaseOne all with a Sony sensor?

The Sony rep was spinning a line in the hopes that gullible people would take a bite.

I believe the decision to with hold the newest sensors from competitors by Sony is a relatively new decision made earlier this year.   The D800/D800E were released before this decision. 

The 50mp sensor is medium format and Sony does not have a medium format camera system.  They have worked with  Hassleblad before.  I think the state of Hassleblad financially was what lead to Pentax and PhaseOne also getting the sensor.  The D800/D800E/D810 are Nikon and it has been proven time and time again that Nikon adds proprietary processing before  writing data to the "RAW" file. 

Both Nikon and Pentax have been getting better results then Sony from Sony senors for a while now.  This is why people in the Sony world complaining about the Sony RAW files not being real RAW files.  Sony sensor division also makes more money selling sensor to Nikon then its own camera division.

You will not see any competitors using the sensor in the 7s and there new high end P/S sensors in competitor cameras for a year at least.  This is what the Sony exec was talking about.

Canon General / Re: DRones vs. anti-DRones: how to resolve the controversy
« on: September 26, 2014, 10:14:01 AM »
I do not thing it will be easy to resolve.  There are a few issues that will keep this alive until Canon beats all other sensors or joins them.  I do not think that Canon will go out of business.  They will swallow their pride and put a Sony Sensor in a DSLR before Canon will go bankrupt. 

  • Human Nature people hate admitting their wrong.
  • Pig headed stubbornness of people that cannot see another point of view.
  • The people that are never satisfied no matter how good their gear is.
  • Trolls Trolls TROLLS will you stop feeding the TROLLS ALREADY. 
The above list will be complaining about something until the end of all internet forums.   

I wish that DR did not bleed into other discussion and ruin them. The 7D II discussions for example.

I am pragmatically in the more DR camp.   The real issue is the read noise.  DR was not something I ever noticed until I bought my Nex6 but the read noise is much more noticeable. 

I cannot use my Sony for what I do with my Canon cameras.  I cannot use my 6D or 60D for what I do with my Nex6.  I am not going to drop all my Canon gear and buy a Nikon the ergonomics are a crime against humanity.

Lets face it a Sony Camera  + Meta-bones adapters really means who needs auto focus.  Because it is so slow you will be manual focusing most of the time.  That is what I like about the Nex6 it forces my to slow down and compose my shot.  But that is not for everyone.

Lenses / Re: Inexpensive standard walk around lens question
« on: September 26, 2014, 09:16:13 AM »
I use my old 28-75 f2.8 Tamron.  I like it has closer focus than the 24-105 f4L and other zooms in its range.  I use it for near macro all the time.  It does not have USM which is a negative.  In many ways it is a very underrated lens.  It is small for a 2.8 zoom and shares a filter size of 67mm with the 70-200f4L.  The two add up to a very good travel set.

EOS-M / Re: EOS M Accessory question
« on: September 18, 2014, 09:58:52 PM »
I bought and sold an EOS M + 22 + 18-55 + adapter.  Then when the second fire sale (at $250) came around, I snagged the M + 22 again and added the adapter as well.  When I had it previously, about the only lens I mounted on it was the 40mm.  However, this time around I have additional lenses and find 2 that work really well with it.  I use the EF 35mm f/2 IS USM and the EF 50mm f/1.4 USM both work wonderfully on it.  The EF 85mm f/1.8 also works well but due to the longer focal length I find it slightly more difficult to compose images and locate my subjects - it's not terrible, but it's not great either.

For me, the 22 + 35 IS + 50 is a GREAT, LIGHTWEIGHT, small(ish) walkaround combo.  Personally, I find zoom lenses on the M to be cumbersome and I don't really like them.  Both the native 18-55 and adapted zooms.  Adapted zooms are worse.  Probably a personal preference.  And note I haven't tried the 11-22 or the 55-200.

I agree, a fast 50 on the M will complement the 22 nicely. Much like a 35-85 combo on FF.
I didn't really like the 50/1.4 though (bought and sold it 3 times), so I am thinking on the FD 50mm lines.

If that is the case go for a M42 mount 50mm.  I could not tell any real optical difference between the FD 50mm 1.8 and the EF 50 1.8.  I expect the FD 50mm 1.4 would be the same.  I have thought about tracking down a FD 55mm  f1.2 that may be worth it.

EOS Bodies / Re: Canon 7DII - Did you preorder?
« on: September 18, 2014, 09:34:20 PM »
Canon usually has enough cameras on had that pre-order is not realty necessary.  I am gong to buy the Tamron 150-600 first.  I also need a full frame wide angle lens then I will think about a new crop camera.

I wil rent a 7D II and a 70D before I make a decision.  I really miss the articulating display of the 60D every time I use my 6D. 

The 7D II looks like a real good camera.  I want to see the 7D II ISO performance and how it performs against a 70D. 

I would have liked to have see:
  • WiFi for remote control
  • Articulating screen
  • A change away from CF to CFast or XQD
  • 4K video

Not that I care for 4K video but I think Canon should stay current.  It always seems that Canon Cameras are released a year late to me.  I do not have CF cards and do not want to buy them for a camera when the next gen will likely replace them  with something faster.

 CF is nearly legacy we should prepare to move on to a serial bus.
