Finally here.  A7R with FE55mm f/1.8.  Reading the manual now, but how do you move the focus point around?

Congratulations, may it serve you well. To change the focus point:
Hit "Fn" button, choose "Focus Area" and select "Flexible Spot M" ... then you can use the Control Wheel on the back of the camera to select the focus point.

In addition to that (I prefer Flexible Spot S, but there's also a large one too), it helps a lot if you assign focus point selection to an external button on the camera, which reduces the number of steps (unless I'm missing something, the smallest number of steps you can take is hit one button then use the four-way control wheel or two of the wheels near the top (one for vertical, the other horizontal, movement); too bad they didn't copy Olympus OM-Ds, where you can set up the rear control wheel so that there's no need to press some other button before using the directional buttons).  I find it most convenient to assign that function to one of the four buttons on the rear control wheel, since that's what I typically use to move the focus point, but there are plenty of other options.

I'm finding I like flex spot S.  Also the C1 button is assigned by default to be AF point movement activator, after which you have to use the two round dials front and back on top for horizontal/vertical movement.  It's kind of a pain and slow, and the dials are too stiff.  I miss my 5D III AF setup but it will have to do.  Oh, and that shutter release button should have been physically more forward. 

Zeiss 55 mm is built way better than I expected from internet pictures, where it kind of looks like my Canon EOS M lenses but way heavier and sturdier.  AF speed seems perfectly fine and accurate too for my purposes, even in dark interiors.  Would hate to slow it down with adapter+Canon lens setup and may spend that $400 for Metabones towards a used Sony/Zeiss 35 mm f/2.8. 

Looking at that Deo-Tech adapter, it looks the same to me as TechArt and RJ visually.  I strongly suspect same oem, and researching them further, Fred Miranda is saying those have more softness and CA in corners compared to Metabones, which suffer from internal reflections themselves  :-\

Canon General / Re: Review: Canon Speedlite Transmitter ST-E3-RT
« on: March 02, 2014, 10:56:17 AM »
So after using my YN-E3-RT in a pro environment for a few weeks I have to say, it sucks. Mine has been unreliable, with regular loss of communication, remote misfires, and very touchy menu interface that only happens when the thing is mounted on a camera.
I now have to take it off camera to make any adjustments to remote or menu settings, once the thing drops a flash you have to go very close to reconnect.
The thing is a frustration, when it works it is fantastic, especially on pre 2012 bodies, when it doesn't, I just want to throw it away. It is not in the same league of reliability as the Canon ST-E3-RT that I also own.



ouch ... too bad ... !
Thanks for sharing your first-hand experience!

x2.  It's too bad Yongnuo could not build a more reliable unit, as it would have been a nice alternative to Canon.  This experience is similar to my experience using Pixel King's on my Canon, which behaved odd at random moments, but ironically the Yongnuo 622C's replaced them and have worked flawlessly  ???

Mark my words, if Fuji ever make FF mirrorless(similar to x100 series & same EVF as Sony), I will sell my A7r and stay there permantly. I LOVE the body design of x100s. I wish A7r has same EVF as x100s, keep the system even more compact.

I just got A7r, and it's been very frustrating trying to find compatible RF wireless TTL triggers and Sony TTL speedlites that don't have overheating issues. 

What's the situation with Fuji as far as RF wireless TTL triggers and TTL speedlites are concerned?

EOS Bodies / Re: Hardware Hack for EOS Cameras Coming Soon? [CR1]
« on: February 28, 2014, 11:12:59 AM »
Now if this hack would give me everything I've been fantasizing about in the a7R

My experience to date with the a7r is if it could be hacked to give 8fps ?? the rest is just fine as is, this Sensor and 8fps, my hopes for a near future 1D body.

I just took delivery of A7R to add to my 5D III, and man, have you "felt" and heard that ridiculously loud and vibrating Sony shutter?  :-\  If somebody made A7R do 8 fps, the shutter assembly would likely contort and explode.

EOS Bodies / Re: EOS M2 Coming to North America & Europe?
« on: February 28, 2014, 11:07:23 AM »
With cameras like Sony A6000 and Fuji X-T1 looming, this M2 news is just too little, too late. 
EOS "M3" with an improved sensor and A6000-like AF prowess coming to North America, now that would be an interesting news.

Great work putting it all together drjlo ... thanks for sharing ... personally I prefer the Metabones, because all my lenses auto focus with it (except 50 f/1.4), also the tripod mount can be easily removed, so the adapter becomes smaller and a tiny bit lighter.

Thanks from me, too.   So far my only AF problem with the Metabones is that my 70-200 f4 IS had a hard time focusing at 200mm.  (Maybe it didn't help that it was below freezing when I tried it; if it ever warms up significantly here I'll try it again!)  No problems with 24-105L, 100L, 85 1.8, 40mm pancake, or 28 IS.  The only Canon mount Sigma lens I own is the 50-500 OS, but I can't imagine ever wanting to attach that monstrosity to my A7r!

Oh, but do try the Sigma on Metabones and let us know if it autofocuses AT ALL, however slow.
It seems awful difficult to find an adapter that will work decent with Sigma lenses, which is a shame since I can see the Sigma ART lenses may on people's minds for A7R.

Researching into AF adapters for A7R, here are the apparent choices:

The ones without AF are pretty cheap, but there are quite a few that preserve AF, IS.  From researching these in an effort to find a reliable one, the user experience seems to be that AF is similarly slow via all of them, and each has different electronics/software leading to one working better with some lenses while another adapter may work better with other lenses (Canon or third party).

Metabones Mk III adapter seems to be the most popular with most user reviews but also the most expensive at $400.  It does not work with all lenses at all, however:
"Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus may be disabled for older Canon lenses and most third-party lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses modified by Conurus."

A Youtube video showing the AF speed with Metabones adapter.

My next choice would be RJ Electronics one which is cheaper with good user reviews available. Some claim it gives sharper results than Metabones III (how?) and works with older Canon lenses unlike Metabones.  RJ admits it does not work well with Sigma lenses.  I read one user who said that Canon 100L Macro did NOT AF when focus limiter was set to 0.3-0.5m (Macro range) but AF was fine at other settings including "Full."

This Viltrox zinc-alloy one seems okay as well.  I have a Viltrox Canon EF to M adapter which works OK though a bit loose on camera end.  One can find a couple of user reviews on line, so at least you know it "works."

I found a video on Youtube that shows AF speed with Viltrox adapter and Canon 17-40L.

This Chinese one is claimed to be made from brass with AF intact.  Unfortunately, no user reviews can be found.

This "King" adapter looks interesting as well but again no reviews can be found.

TechArt version II adapter. 

It's thought TechArt and RJ adapters may be from same oem, sharing the black finish on the camera side and also sharing the inability to recognize focus-limiter on Canon lenses.  It's selling a little cheaper than RJ.

Deo-Tech Falcon adapter

This one also looks to be the same adapter as RJ and TechArt
http://www.deo-tech.com/

Upon further research, some users including Fred Miranda are reporting that RJ/TechArt/Deo-Tech adapters are softer with more CA in the edges compared to Metabones III.

Lenses / Re: 24-70/2.8 Canon or Tamron: Which did you choose and why?
« on: February 26, 2014, 03:18:45 PM »

Tamron's VC or Canon IS will not help with people photography in dimly lit indoor situations ... coz people move

At say 50 mm focal length, with adults "trying" to pose and not move, what minimum shutter speed would be typically required for subject motion?

Looking over my shots, I actually got some very sharp photos at around 65 mm at 1/30th. 
Some of the moderately blurred photos were for example 61 mm at 1/16 th !  Didn't even realize how slow shutter speed was due to trying to run after people.  So in these situations, IS/VC would not have helped anyway?

Third Party Manufacturers / Re: Sony raw files lossy compressed
« on: February 26, 2014, 12:33:20 AM »
I agree most will never notice this.

But, I also agree that this is the sort of thing that will totally turn off some from ever using the camera professionally.  So if Sony wants that market, next version of the camera needs to fix this.

I don't think this RAW issue is ANYWHERE as large a roadblock to professional use as Sony's complete incompetence or unwillingness to develop a functioning pro-level speedlites and RF wireless transceiver system that can be reliably used at weddings, events, etc.  The impact on photo's will be a million times more noticeable than any issues caused by the Sony RAW.

Lenses / Re: 24-70/2.8 Canon or Tamron: Which did you choose and why?
« on: February 25, 2014, 04:17:50 PM »

In my opinion the Tamron 24-70 VC is better then the Canon version 1 and about 90% as good as version II at half the price. But if I had the money at that time, I would have still bought the Canon II again.
 

I just shot a baby birthday at an indoor restaurant in evening with 5D III and Canon 24-70 II and found some of the photo's had blur.  I had kept iso at 800 to get clean photo's with flash firing on camera (bounce), but on some of the longer focals >50 mm and group shots requiring narrower aperture, my hand shake got in the way.  Would the Tamron's VC solve this problem in practicality?  The more I shoot dim events, the more I wish my 24-70 II had IS  :-\

72

maybe JPG noise reduction.. a bit more smear... a bit less noise? :)

I suspect Nikon is talking about jpeg noise improvement, kind of like how Canon hyped jpeg improvement when 5D III came out. 

D4s is yawn city, but perhaps people who wanted D4 can get one cheaper now. 
Instead of D4s, the camera Canon needs to respond to is Nikon D5300, which really makes the current Rebels look embarrassing  :-[

Again, for an f/1.8 aperture prime, the Sony FE 55mm seems very expensive for what it is.  I believe the main reason it is so expensive is because it has a captive market with no other native prime at that focal length available. (

I agree Sony pricing is wacky, e.g. behold the RX1R and accessory pricing.  I probably would not have bought the FE 55 mm, or the A7R, if it werent' for the great deal at Focus Camera.  I have owned Canon 50 f/1.8II, Canon 50 f/1.4, Canon FL 55 mm f/1.2 (converted to EOS), Canon 50L, and I have used the Sigma 50 f/1.4 (non-ART).  I have sold them off one by one and am left with only the 50L, which I would have sold except it works great with 5D III AF system despite its issues.  Heck, the 50 mm range of my Canon 24-70 II probably is the sharpest of all of them.

Unlike many who find the 50 mm range boring, I love that focal length, and I blame Canon for not coming up with a truly great fast 50 mm for so long, too busy putting IS on their wide angles  :'(  The FL 55mm f/1.2 was fun, but manual focusing at wide apertures just took too long to be useful in real life for events, people, kids, etc.

The FE55 mm should hopefully fill my 50 mm void until Canon puts out a worthy one, a simple 50 mm f1.8 or f1.4 with good sharpness wide open and rounded blades/better bokeh would be sufficient.  I fear Canon will price it $8-900 even for non-L, if it ever comes out, though.  Just hope it will not be a 50 f/2.0 IS for $1000  >:(

Anybody using the Sony/Zeiss FE 55mm lens yet? 

DXO testing shows results very close to the Otus 55 mm, in fact second best for any lens behind Otus and the best audiofocus lens DXO has every tested.  I should receive one soon along with A7R; I just hope all the ergonomic issues, Sony-specific software/hardware issues don't make me regret buying that combo to use alongside my 5D III.

Third Party Manufacturers / Re: Sony A7/R "Bundle Deal" up to $650 Off
« on: February 21, 2014, 06:33:28 PM »
FYI, doing some more research, the RJ Electronics adapter is reported to be well-built with AF as good (maybe more precise?) as Metabones III.  It's a bit cheaper at $289.
