Third Party Manufacturers / Re: How Strong is a Sony Lens Mount
« on: October 20, 2014, 10:27:18 PM »
I just about guarantee it would snap off with a 400f5.6 attached, and that's a "light" lens.

Hooking a 400f5.6 to a E mount camera is much like hooking it up to an EOS M.  The camera cannot be used for little more than to stabilize you holding the lens.  And if you are hooked to the Lens instead of the Camera the Camera is more that capable of supporting its self. 

Ether way unless used as a backup a 400f5.6 is not realty in the use case for a small mirrorless camera.  Not to mention that unless it is real stead focusing on that long of a lens with is mirrorless camera is a serious pain.  I would stick to using a DSLR for that.

If it is really that much of an issue someone will find the replacement part Number for the mount on a A7s and get an official solid metal mount.

I have never had a problem with mine.  I do not know how big of a lines you would need to actual make it an issue. On the E mount the second part is thought to be designed as a break point.  Most cameras have a designed brake point to protect the body and lens.  Canon places this on the lens side. 

I only see this as and issue with larger adapted lens.  But I have never noticed an issue hooking my Canon 70-200f4L the few time I have done it. 

Lets face it there are plenty of real life Tim "The Tool Man" Taylors in the world. Who look at it and decided this would be better as all metal.  They will likely be sending their cameras into Sony after sticking a screw driver into the sensor shortly. ;)

EOS-M / Re: Recommendations for lens to supplement EF-M 22mm?
« on: October 19, 2014, 07:48:03 PM »
I suggest getting the  EF-M 18-55mm.  I would also choose the 40mm over the EF50 1.8 II.  I really don't like the Nifty 50.  It is not sharp enough for me until stopped down.  I The 40mm is sharp wide open and it is in my opinion easier to manual focus. 

I also have an old FD 50f1.8 S.C. to be honest the optical performance between the EF50 1.8 II and the FD50 1.8 is about the same.  The coatings on EF50 are a little better but the manual focus of the FD is better.

Reviews / Re: Camera Store Trashes New G7X
« on: October 19, 2014, 03:47:16 PM »
The last time I even considered buying a Canon P&S was in 2009.  I was seriously considering buying a G11.  I ended up going to a bunch of camera stores and trying all of the High end P&S.  I came to the conclusion that Sony, Olympus and Fuji-film all built more feature pact and compelling cameras.  This was mostly because the Canon was more expensive and lacking features the other cameras had.  In my mind the only thing that the G11 had going for it was that it was a Canon and it had raw image support.

In the end I decided that none of the current P&S really me my needs.  So I bought a Rebel and the lens I needed. 

The video really just echos my perception of Canon P&S developed at that time. 

If I was in the market for a P&S I would not even consider a Canon.  Unless it was blowing away the competition in reviews.

Speedlites, Printers, Accessories / Re: Lexar CF cards FAIL - Sandisk?
« on: October 19, 2014, 09:58:05 AM »
I just had a Lexar 32GB 1000x card fail and Lexar support told me that if I wasn't using a UDMA7 card reader that eventually all my UDMA7  cards would fail. I had been using an older firewire800/non-UDMA7  card reader and have now switched to the latest card reader from Lexar. Never heard of that before but that is directly from Lexar.

From an electronics, engineering and otherwise common sense viewpoint, what they told you is total hogwash.

I'm an IT guy by trade, I've been immersed in various electronics for 30 years and I have never heard anything so ridiculous.  If you can find this odd fact confirmed somewhere, fine, I'll eat my words but in general, a reader is just that, a reader.  The SD specifications for compatibility state how the device, chipset and firmware are supposed to work and SD cards & readers are backward compatible.  If they weren't, there would be some physical notch preventing insertion.

http://kb.sandisk.com/app/answers/detail/a_id/2520/~/sd%2Fsdhc%2Fsdxc-specifications-and-compatibility

The only thing that is going to cause compatibility problems has to do with the upper level file system format (FAT32, exFAT, etc) not how the device is accessed by the reader itself.

The only difference between the different specifications is transfer rate.  Period.

He is talking about a CF card not a SD card.  Everything you said is true for SD cards.  However, CF cards have a Hard Drive controller on board.  So it is very much like reading a new HD on an old controller that does not support all the features.  It could very well cause the card to fail over time.   Not all CF cards are equal.  In the lab at work we had a number of Sandisk CF fail do slight incompatibilities.  They would work for a while then just die and no amount of formatting would fix them.  Mind you we were using them in Embedded Computers as HD.  There was nothing wrong with they cards they were just incompatible. 

So what Lexar told said is likely correct.

Lenses / Re: Building my lens system - where to go from my basic kit?
« on: October 18, 2014, 10:07:57 PM »
I vote for a variation on 2.But, I would keep the 24-105f4 for its versatility.  I would consider get a 70-200f4 IS and a  1.4x TC instead of the 70-300L.  To use as a travel light kit.  Then latter buy the 70-200 2.8 II and a 2x TC before going on Safari. 

I have nothing against the 70-300 F4-5.6 L but it does not take the canon extenders.

I when traveling light I try to limit my self to what I can carry in a Lowepro Adventure 170. I am very sure that my 6D, Tamron 28-75f2.8, 70-200f4, and a 16-35f4IS will fit.  It will be very tight I might have to leave the lens hood for the 70-200 at home ;).  The 70-300L is to fat to fit in my Adventrure 170 with the other lenses. :(

I came to the conclusion that I would own a 70-200f4 and a 70-200f2.8L at the very beginning. The 70-300L was not out at the time.

EOS Bodies - For Stills / Re: So what makes a camera a "pro" camera?
« on: October 18, 2014, 10:51:56 AM »
Not sold by Best Buy :)

I think it depends on the Best Buy mine has Canon 5D III and other relatively high end cameras.  If you really felt like it you can order a 1dx from Best Buy :).   http://www.bestbuy.com/site/canon-eos-1d-x-digital-slr-camera-body-only-black/6304299.p;jsessionid=3701442F8BA8C909E6B058C19C5127C1.bbolsp-app01-121?id=1218726452741&skuId=6304299&st=canon 1Dx&cp=1&lp=1

I guess you do not consider a 1dx pro enough.

What is even more crazy is you could order a Canon 5D III with the 24-105L from Walmart and have in store pick up.   At least if they were in stock.  I also so a Nikon Df on there in black and Silver.  The Df is in stock.

I vote for the 6D as well.   The 7D II will still be ISO limited compared to a full frame camera.  For the 7D II you need to factor in the cost of CF cards to get the full benefit of the Camera.
 
I was checking the Canon USA website it looks like they only put in a standard speed SD card reader.  There was no mention of a UHS-1 compatibility.  I do not own CF cards.  The 7D II may suffer the same performance issues at the 5D III when using SD cards. 

For general everyday use I would take a 6D any day over a 7D II.  But I could use a high speed demon off a camera for birds. But given the coast I plan on renting one first.  Then I will make my decision.

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.

EOS Bodies / Re: mirrorless ?
« on: September 29, 2014, 09:00:45 AM »
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.
