After much research, I bought the Commlite adapter, but other users' input regarding others would be appreciated.

The current  EF to FE adapter situation is very mirky.  I would like an adapter with better AF speed than ones on the market right now, even Metabones III, now IV.  Also, even the better-reviewed ones like Metabones and RJ adapters are supposed to not work well with third-party lenses especially Sigma, which is disappointing since the advent of Sigma ART 35 and upcoming ART 50mm lens.  My research so far turned up the following.
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 seemed to be the most popular with most user reviews but also the most expensive at $400. 
Metabones Mk III's AF speed is slow and typical:

It's since been updated with Metabones Mk IV, but disappointingly, according to Metabones, there has been no AF speed improvement from Mk III to IV, just bigger opening to accomidate tilt-shift lenses and anti-reflective coating inside:

This Youtube video comparing Viltrox, Metabones IV, and Commlite also seems to indicate Commlite may work even better than Metabones IV:

Mk III did not work with all lenses, 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. A lot of users are reporting internal reflections causing funny colors and CA at edges, and there is a DIY fix using adhesive-backed velour to cover up the adapter internals.

However, Metabones IV is reported to be too tight on lens side fit along with other issues.  The video also shows why non-smart adapters like Vello can't be used:

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.

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 &quot;works.&quot;

I found a video on Youtube that shows AF speed with Viltrox adapter:

Fotodiox Pro adapter, at similar price to Commlite.  The lens side is metal, but camera side seems plastic.

AF speed seems similar to others.

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.
<a href="" rel="nofollow"></a>
Deo-Tech Falcon adapter
<a href="" rel="nofollow"></a>
This one also looks to be the same adapter as RJ and TechArt
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.

Deo-Tech now makes Mk III, which now shows the label &quot;Tech-Art&quot;!

Well, I ended up returning the Sony A7r but recently bought it again with the Zeiss FE55 f/1.8 lens.  The adapter I did end up getting is the Commlite FE-NEX adapter.  Based on reviews I read, none of the adapters, even the pricy Metabones, auto-focuses fast, so I bought one that is reported to have AF at least as good as others with least reports of issues. 
This Youtube video comparing Viltrox, Metabones IV, and Commlite also seems to indicate Commlite works even better than Metabones IV:

Commlite FE-NEX adapter:

Good news first.  Its build quality is quite good with nice metal contact areas and sturdy-feeling switch and smooth mount/unmount.  AF speed was surprisingly fast with Canon lenses I most likely would want speedy AF from, e.g. Canon EF 24-70 f/2.8 II, Canon 35L. 

BTW, It's a joy to use the Canon T-SE 24mm II with its fabulous MF ring with this adapter and Sony's focus peaking.  Fantastic!

Now bad news.  Longer focal length lenses don't AF as well with lots of hunting issues.  Canon 100L macro was especially slow with no useful AF to speak of.  I expected better, but Canon 70-200 f/2.8 II did not AF well at all with the adapter setup.  Pity that... To add to the insult, Canon 85L II would not even mount physically on the Commlite adapter.  Something catches mechanically and the 85L cannot be screwed on all the way. 

All in all, I got pretty much what I expected going in, with nice build quality for the low price I paid.

EOS-M / EOS M3 24 MP Sensor?
« on: January 29, 2015, 05:45:47 PM »

EOS M3 may arrive with a 24 MP sensor, and since it may be unlikely that Canon has developed both the 20 MP sensor (7D II) and yet another new sensor at 24 MP, could this be the ubiquitous Sony 24 MP sensor?   If so, how do we feel about this?    :o

Third Party Manufacturers / Samsung NX400 with NX1 BSI sensor
« on: December 22, 2014, 07:28:03 PM »

Smaller body NX400 with the NX1 BSI sensor, around $900 with kit lens.  If true as rumored, that will be my next camera purchase to supplement my 5D III, seeing how nothing similar is coming forth from Canon  :'(

Since installing Magic Lantern 1.2.3 on 5D III, I have noticed that my files shot at 0 EV exposure comp are wrongly tagged as either +1/3 EV (seen in Digital Photo Professional) or "+1 Step" (in Windows Explorer window, flickr). 

Files shot with +1/3 EV are wrongly tagged as +1/2 EV (DPP) and "+0.5 Step" in Windows explorer and +1 EV in flickr.  A files shot with +2/3 EV actually showed as nonsense under flickr EXIF,  "-1&#x2F;2 EV"

Has anyone noticed similar problems since installing Magic Lantern 1.2.3. on 5D III?  Any way to fix this or could this possibly be some other issue, although the only change has been Magic Lantern?

Below are examples:

A very detailed, thoughtful review of the interesting Pentax 645Z, with comparisons to Nikon D810 even and a serious effort to look into video capabilities.


Having purchased and returned the Sony A7R 36 MP high-MP monster, I was hoping for a Sony camera with same sensor but better/faster AF similar to Sony A6000, but this A7S with 12.2 MP threw me for a loop from the left field.  With such huge pixel size, it *should* have unheard-of dynamic range at high ISO, something even D800/A7R cannot manage at high ISO.  With -4.0 EV AF, it should have fabulous AF in low light, and if color fidelity and IQ benefit from large pixels, this camera could be THE walk-around, low-light monster we have never seen before.  Although this camera should appeal to videographers, it could seduce photographers who shoot low-light events. 

Hate to say it, but Sony does seem to be towering over Canikon when it comes to imagination, innovation, and appetizing cameras  :'(

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 / Sony A7/R "Bundle Deal" up to $650 Off
« on: February 10, 2014, 02:08:48 PM »
Sony A7/R and lens sales must not be great, as Sony started a "Bundle Sale," with $200 off body+one lens and $650 off body+one lens+F60M flash.  Be aware, the F60M flash is riddled with overheating problems which Sony will not own up to, but $99 for a $600 flash may be worth it for those not needing rapid firing or willing to repair it on their own (supposedly $100 for repair at

Reviews say Corel is comparable to Lightroom/Aperture but takes less computer resources.

I can't believe it, but DxO FilmPack 3 is offered for free.  I just downloaded it, activated it, and yes it's free and works.  It's very similar to Nik ColorEfex Pro which I also have.

I just received a newsletter about Rogue's "Safari" flash-booster.  Looks great and appears better built than the "Better Beamer," but it is only meant for pop-up flashes.  I have already e-mailed Rogue to request a version for regular flashes and would like to encourage others to request the same.  TIA.

I have come to the conclusion that I simply am not motivated enough to carry traditional light-stands when I'm asked to "take some photos" as a favor to acquaintances at things like baby birthdays, social gatherings, etc. 

I have some traditional "portable" softboxes and even a lumodi beauty dish, but unless it's a paid gig, I'm simply not motivated enough for the hassle.  As a compromise, I have bought some Rogue Flashbenders/diffusers, which are working out great for ultra-portable 2-light setup.  However, light stands are still a problem.  I do have some Manfrotto Nano clones and some slightly bigger ones, but what are some out-of-box alternatives for portable light stands that just needs to support a speedlite with Flashbender?  I am looking at some microphone stands, maybe even some carbon tripods (have some), which are not that small actually.

EOSD4447 by drjlo1, on Flickr

My copy of 24-70 f/2.8 II needs -9 at wide end and 0 at tele end on my 5D III.  My Canon 70-200 f/2.8 II needs 0 at either end, and my 100L also needs 0.  Some of my fast primes including 35L, 50L, 85L II range between -1 and -3. 

A brand new Canon 17-40 f/4L I just borrowed needed -6 at wide and 0 at tele. 

-9 seems a tad too much for a $2100 lens, so I'm just wondering what 24-70 f/2.8 II owners have experienced with AFMA (and 5D III)?  Is it worth sending in the lens to Canon while still under warranty for calibration?

Is my copy of 5D III partly at fault here, as the body seems to need Minus AFMA on lenses, never positive.  The body is out of warranty, but should I send in both the 24-70 II and body to Canon for calibration together (does Canon even calibrate a specific lens+body combo?). 

Any help would be appreciated.
