Unfortunately, The Sony/Zeiss 24-70 f/4 OSS lens has received disappointing reviews at both photozone and SLRgear.


EOS-M / Re: EOS-M first impressions
« on: March 26, 2014, 10:23:06 PM »

I actually find it very convenient and use it like this (touchscreen shutter activation needs to be off):
- touch the screen where I want to focus (right thumb)
- press the '*' button to focus (with the right thumb which is already positioned close to the button)


I would have loved the EOS-M touchscreen and its touch-to-focus feature on my Sony A7R.  I would have gladly traded away the Sony EVF for the touchscreen which makes it 10x faster to move the AF point than A7R's ludicrous two-dial system.  Yes, I still can't stand EVF's.

Personally, I would love something like a mirrorless (smaller) version of Tokina 35mm f/2.8 AT-X PRO DX Macro lens, but make it EF-M 35 f/2 Macro.  It doesn't even have to 1:1 macro like Tokina, but 1:1.5-2.0 would suffice and also would be great people/event lens.

EOS Bodies / Re: Problem with MK3 new 1.2.3 firmware

Are you sure it's due to the new firware?  Something similar to what you describe have happened to me in past, but with 5D III and 1.2.1 firmware, using 90EX as optical ETTL trigger with off-camera 580EX II..


I agree with Rienz. I think in a couple years time the situation might be very different. Sony has still a so-so reputation in the photographic world, but if/when Fuji will release a FF X system, then the whole market might reconsider its position.

I had hoped Fuji would go FF based on rumors, but it looks unlikely according to this interview with Fuji executive:

Yes, we have a couple of years to consider things.  By then, a Canon 5D MKIV will be apparent, and depending on what Canon does with new sensor (or not  :-[), many will consider other options including Sony.  Hopefully, by then Sony will have: improved customer service, fixed their overheating speedlite, introduced some TTL triggers, made their RAW lossless, fixed the shutter vibration, improved AF on FF, etc.

the 5DIII is definitely yet another big step up from the 7D, particularly with subject tracking.  Being able to lock an AF point on a bird and have it track it over 2/3 of the frame is amazing.

I am still experimenting with 5D III for BIF, which is a bit difficult due to AF point not lighting up in Al servo and 6 fps.  Which Al servo "mode" do you prefer for BIF, and which AF point distribution (all AF pts on, double cross only, center only, center expanded, etc)?

The 50 1.4 is an excellent lens, no doubt about it.  It was my first prime on a DSLR and what made me fall in love with photography all over again.

You guys started with luxury.  My first DSLR prime was the Canon 50 f/1.8 II for around $100, and it was a mini revelation  ;D  Then I went through the 50 f1.4 (great lens), even FL 50 f/1.2, then 50L, with stops along the way with Sigma 50 f/1.4.  What amazes me is how Canon still has not updated the non-L 50 f/1.4.  One would think a little tweak in the optics, with more/rounded blades for better bokeh, with updated USM AF system would produce an excellent 50 f1.4 II.

Lenses / Re: 16-35 II vs what?
« on: March 20, 2014, 09:46:59 PM »
I tried the 16-35 II and 17-40, and really, they are pretty good, way better than what one would guess by reading comments by people who say they are "cr&&&" or "unusable." They can produce very good results, especially when one applies appropriate type and amount of lens correction that are readily available. 

I also believe many people who think they "need" f/2.8 in wide angle probably don't.  Perhaps if you shoot a lot of real-estate interior shots in dim lighting, but then again, proper lighting and tripods should resolve that. 

The 17-40 I tried was of recent build, and I don't understand why people say it's much worse than 16-35; maybe the older productions were worse?  ???

If one must produce and sell wide angle photo's in large print sizes with absolutely perfect corners, then maybe this Canon "Year of the lens" thing will work out in the way of a new Canon 14-24 or 16-35 Mk III..

According to http://www.sansmirror.com/lenses/lens-database/sony-nex-lenses/ ... these are the 15 FE lenses that will be available (in or before the end of 20015) "in order of likely introduction":

3. FE 55mm f/1.8 Zeiss (Available)

4. FE 24-70mm f/4 Zeiss OSS (Available)

5. FE 70-200mm f/4 G OSS (Available for Pre-Order)

6. FE 16-35mm f/4 Zeiss OSS (2014)

7. FE 85mm f/1.8 Zeiss OSS (2014)

8. FE 100mm f/2.8 Macro G (2014)

9. FE 35mm f/1.4 Zeiss (2014)

10. FE 24mm f/2 Zeiss (2014)

13. FE 21mm f/2.8 Zeiss (2015)

15. FE 50mm f/1.2 Zeiss (2015)

See, this is a real problem.  Looking at the $$$ price Sony is selling their Zeiss FE glass, if I commit to the FE system, the lenses above are the lenses I would likely want, to at least half-way approximate my Canon lens system (minus my T-SE, MP-E, etc) We are talking about a lot, a LOT of money here, which I (and most) cannot afford IN ADDITION to the Canon glass we have already invested into.     

It has color saturation and contrast that are as good as my 180 Macro and 300 2.8 IS II, resists flare beautifully and has the best bokeh of any lens I've used other than the 85 II. 

I love my 85L II to pieces, but it's too long for indoor shoots, and its longer focal requires faster shutter speeds in dim interior to avoid blur.  If Canon can put IS on it without compromising IQ, I can sell a whole bunch of other lenses. 

As far as 50L, there's no denying the unusually nice color and contrast compared to other Canon 50 offerings, but the sharpness "issue" is too overemphasized IMO.  For example, the 50L is STILL the sharpest 50 mm in the world at f/1.2  ;)

Also, it may surprise many, but the 50L is even sharper than the vaunted Zeiss 50 f/2 at the same f/2.

For those who sigh over 50L's CA wide open (85L also for that matter), I strongly recommend you try Canon DPP's DLO (Digital Lens Optimizer), which IME produces MUCH better CA removal and sharpening compared to the usual Lens Correction.  If you are bothered by the larger resulting RAW size, all you have to do is unclick the DLO function when you close/save RAW.   

Lenses / Re: Sigma 50mm F/1.4 Art listed in Belarus for $790

This will kill sales of Canon's 50/1.2L - even at its current rebate price of  $1,469.00. The Sigma is almost half the price of the "L".

Dunno about that. I just met a guy who recently bought a 35L and loves it, and he happily paid almost double the price of the superior Sigma 35A.

Although I hope and pray the Sigma 50 ART turns out to be a great lens, with perfect AF and no third-party issues, my own needs revolve more around the overall "look and feel" and color than sheer sharpness.  This is why 35L fits my own needs better than Sigma 35 ART, so I understand that "guy" who loves his 35L. 

I truly hope the Sigma 50 ART can bring lively colors and subject separation/"pop" from wonderful background bokeh, then I will replace my 50L with it. 

When I removed the spent batteries, a small piece of plastic followed the batteries out the door.

Where exactly did that come from - anything you suggest to prevent this from happening?

As for the reliability: Just from a couple of posts in a forum - no matter positive or negative - we'll never get a good survey, esp. there's a bias against 3rd party manufacturers: If Sigma/Yongnuo/... breaks it'll be on the Internet as a systematic failure, when Canon breaks it's an isolated case covered by the warranty. Still, I do regret ordering the Trigger as cheap as it comes from an obscure eBay seller as I doubt he'll make good on the warranty (if there's any).

The piece came out of the guts of the camera. Nothing extraordinary caused this to happen. I can see nothing broken/missing when I look inside the door. There is another piece rattling around inside the transmitter that just wont fall out. The unit still works fine, but it will drain the batteries in about a week even when powered off. I have been in contact with hkyongnuophotoequipment and have sent them pictures/descriptions of the problem. They have asked me to send the unit back to them for a refund or replacement, so they appear, so far, to be handling this in a professional manner. I have since picked up a Canon ST-E3-RT as I already have 2 600EX's and so am committed to the system. I'm not sure whether I want a refund or replacement. I still use a 5Dll and a 7D, and I also find the focus assist light occasionally useful. I will probably go ahead and get a refund for now. The price of them has gone down to $138 on ebay and I suspect they will drop further, so I may pick up another one in the future.

Are you stuck with return shipping fee back to Hong Kong? 

EOS-M / Re: EOS M to augment 5D3 and replace g12
« on: March 18, 2014, 03:39:14 PM »
Can't really beat EOS-M with EF-M 22 mm for portability and aps-c IQ.  I paid very little for mine including the 90EX flash (thanks B&H!), and if I were you, I would look on ebay for much cheaper deals from those who got them on sale; they are all practically new. 

The 90EX is laughed at, but it's a great optical trigger for off-camera Canon flash.  This is the way I use the 90EX, say with off-camera 430EX II with gorilla pod, to create some bona-fide strobist DSLR images.  I usually hate kit lenses, but the EF-M 18-55 is crazy good for the money. 

What is the potential risk with ML anyway? I believe I've read something about frying your sensor (!) when using Dual-ISO. Is that a big risk and if so, why?
No risk. ML runs on your memory card, the moment you replace the memory card, there is no ML ... use it without fear.

My understanding is that once you install it on the 5DIII you cannot undo the boot flag. This means that if you don't like it (slow boot times, or something else), you can't "reset" your cmaera to factory performance. That is a barrier to me. I'll give it a try when I see that it is completely reversible.

I thought the ML 1.2.3 version DOES make bootflag reversible?

"What's hot:
- bootflag issue solved! (p.s. some bloggers got it wrong, you still enable it in the camera, but you can disable it by uninstalling)"

Do NOT delete the .CR2 files. The CR2HDR.exe has been improved many times in the past so it will most probably get improved again. You may need to process your .CR2 files again...

+1 - that's one of the main drawbacks of dual_iso, it's a lossy conversion cr2->dng and as you will want to keep the original cr2 around there's double the storage space vs. a normal. shot. Only use dual_iso if you know the dynamic range of the sensor has been maxed out (look at the raw histogram or use ettr with dual_iso link).

I don't know how you guys do it, but it seems like one HAS to physically copy the CR2 files from camera/SD/CF to the folder containing CR2HDR.exec anyway in order for it to convert.  I've been just keeping the original CR2 files in my usual folders, just deleting the copied CR2 files from CR2HDR folder after processing.

So far in my testing, it does not seem like dual iso will be necessary for my usual shooting situations, only when I encounter near-ridiculous situations.  But it's good to have. 
Do you guys have the auto ETTR linked to dual iso when you shoot?
ML's auto ETTR does not seem to be producing photo's with histogram moved all the way right for some reason, even if I have it turned on all the time, and the exposure seems to differ even if I shoot the same scene multiple times with focus point on same object. 

Also, if I set auto ETTR to trigger with "Set" button, can "Set" be pressed to achieve ETTR BEFORE auto-focus is achieved, or does AF have to lock before ETTR can happen with trigger button?
