Lighting / Re: What 3rd party flash?
« on: October 28, 2014, 01:35:32 PM »
Thanks for everyone's recommendations. I went ahead and ordered a Pixel Mago, it arrived yesterday. Looks great overall, my issue is that I am unable to connect it to a PC to flash new firmware (which I need to do in order to enable S1/S2). The device is not recognized by Windows, Code 43 in Device Manager. I've tried on 4 different PCs/ laptops, Windows XP/ 7/ 8.1, same result everywhere.
More details in the screenshots attached.

Thoughts? Has anyone encountered this issue?

Edit: The issue was that I did not have OK pressed on the flash when attaching the USB cable. My fault.
My next issue is that the latest firmware won't flash, Firmware Error 01 -- apparently I got a X650C, not a Mago. Still S1/ S2 works as expected! I am attaching the original firmware in case anyone needs it.

Lighting / What 3rd party flash?
« on: September 28, 2014, 04:14:39 AM »
Hi, I currently own a 430EX and a 580EX, along with a number of Canon cameras (DSLR and Powershot).

I am looking for two extra flashes:

Flash A, to be used off-camera:
Must have:
  • ETTL optical slave (Canon optical wireless)
  • Dumb slave, so that I can trigger it with my Powershot
Nice to have: some kind of radio slave support, any system.

Flash B, to be used on- and off-camera:
Must have:
  • ETTL optical master & slave (Canon optical wireless)
  • Dumb slave, so that I can trigger it with my Powershot (currently S90)
  • zoom
  • AF assist (reliable)
  • some kind of radio master & slave support, any system
Nice to have: video LED.

What are the current choices?

PowerShot / Re: The New Canon PowerShot G7 X
« on: September 14, 2014, 09:34:40 AM »
Overall, I think I am going to buy it, unless they seriously underdeliver on something...

I wonder about video performance (AF, can it chase my 2 year old daugther playing, not a huge challenge given the relative DOF) and whether this thing is able to control speedlites -- I'd love it, I usually have a few set up around the house at any given time but I don't always feel like grabbing the full DSLR setup, the ability to use a much smaller cam with that would be great. Not holding my breath though, knowing Canon...

PowerShot / Re: The New Canon PowerShot G7 X
« on: September 14, 2014, 09:25:44 AM »
I'm not a fan of these things being labled 1" Sensors... I hope everyone considering this thing is aware it's much smaller than an inch and only around 15.9mm measured diagonally!
I am not. What do you mean?
Go buy an EOS M instead ;)
I'd love to, I need fast & reliable AF though, at least on par with 7D. Lacking this I think I'll stay with my trusty S90 :)

If the G7 X has the S120 form factor, it will fit in a jeans pocket.
Yeah, has it? Compared to S120 -- the sensor is bigger, the lens it faster, the screen is articulated. As much as I'd like to believe the S series form factor and size -- is this possible?

Underrated lenses:
  • EF 135L ("so old!", "no IS") -- I hesitated waaay too long before I bought it...
  • EF 35mm f/2 -- very sharp in center (in corners not so much), short minimum focusing distance, very accurate AF -- this is a viable alternative to my 24-70 f/2.8 Mk II in many situations, it's way lighter, it's way smaller. I often use it for video (manual focus is very OK, fairly accurate and barely audible). It's excellent for closeup portraits, with face details, like eyes.

Overrated lenses:
  • EF 85mm f/1.8 -- no contrast, AF often misses (which negates the overall sharpness argument).
  • EF-S 15-85mm f/1.8 -- AF unacceptable for a walkaround zoom.

This is all on crop, 7D, BTW.

...if they could add master function in the 430ex II replacement, I am definitely in.

Unlikely.  There's no technical reason the 430EX II can't be a master, the control signals for Canon's optical triggering come from the main flash tube, and the 430EX II obviously has one of those.  So expect a replacement 4x0EX flash to be slave only, but able to be triggered by both RF (600EX-RT or ST-E3-RT) or optical masters.
A few years ago I'd have agreed completely with this prediction however today I am not completely sure -- Canon seem to be trying to catch up by adding wireless and master capability to their smaller flashes.

430EX is a special case (from the market perspective) that is not very likely to get Master but seeing where things are going I wouldn't be surprised if Canon did just that.

Personally, I only care because I need something that can trigger remote flashes (optical or RT), doesn't necessarily have to flash itself but it needs to have solid AF assist. Even if Canon add RT master capability to their next gen cams (and I hope they will, there's nothing preventing them from doing so, especially that the business case is already there with 7D being able to be Master), I will still miss the latter -- thus I am very interested in a flash that is lighter than 580EX/ 600EX, like the 430EX replacement or (better) 270EX / 320EX / 380EX replacement -- with RT/ optical master and real AF assist (the red lights); I could use the LED light as well, but that's a minor thing.

Speedlites, Printers, Accessories / Re: mini review: Yongnuo 568EX
« on: April 07, 2013, 01:37:46 AM »
Hi, does anyone know if YN-568EX (or YN-565EX) can be used as a slave for a Powershot S90 / S95 / S100 / S110? I mean a dumb slave in manual mode of course (I'd like to bounce it from the ceiling).
You can use even the cheaper YN 560 II that way.
Well, maybe, but I am looking for a flash that I will be able to use with my DSLR in all-auto ETTL mode (to go with my Canon Speedlites) *and* in dumb mode with my Powershot.

Can anyone confirm these flashes actually work with Sxx as optical slaves, are there any problems with the preflashes that the Powershot emits?

Lenses / Re: About to buy the 135L, and then saw this....
« on: October 01, 2012, 03:55:05 PM »
I'm going to buy the 135L, but I'm just curious as to what others think about this, and what the explanation is for their resolution score for the 85 1.8? 
DxO -- others have already said what they think of their scores.

The lenses -- I've had the 85mm f/1.8 for a few years, it is a good lens (with some known drawbacks). However, I don't like it since it delayed my decision to buy the 135L (having a fast 85mm prime and a 70-200, buying a 135mm did not seem that important). The 135L -- well, I *love* it. Scores cannot describe it, people will say it's the bokeh, sharpness, colors, etc. It's a bit of pain to use sometimes (I am on crop) but the photos are just wonderful. It's as much of a jump in quality for me as my first prime (50mm f/1.8 ) was (after cheap zooms).

135L is magic.

Lenses / Re: best wide or ultra wide angle lens for crop sensorh
« on: August 17, 2012, 03:15:56 AM »
I have the EF-S 10-22mm and I wholeheartedly recommend it. It is an excellent lens.

Never used the Tokina 11-16 so I can't comment.

EOS Bodies - For Stills / Re: Canon 40D or XS
« on: August 17, 2012, 02:58:07 AM »
XS is 1000D, right? Fairly old as well, and lower end, so I think I'd go for the 40D and just factor in shutter repair.

I do have a 40D and the shutter failed -- it started failing at 15k (Err 99, first battery removal was helping, then only Live View worked), then died completely at 25k. An authorized Canon repair service charged 60 EUR for the repair.

EOS Bodies - For Stills / Re: Canon GPS Options
« on: August 17, 2012, 02:42:29 AM »
I use a standalone GPS logger (not a nav device, not a smartphone) for this purpose.

My model is a Holux M-1000C (not really a recommendation but I can't complain -- reasonably priced, 20+ hours of logging on one battery, spare batteries readily available as it uses one of the popular Nokia phone batteries).
There's plenty of options, just choose whatever suits you: http://www.bt747.org/compatible_gps

I download the track and convert it to GPX using http://www.bt747.org/ -- requires getting used to as it has its quirks but does the job.

I then geotag the photos using Exiftool, http://www.sno.phy.queensu.ca/~phil/exiftool/. It cross references the dates/ times in the EXIF data in CR2 and JPG with the GPX file and updates the EXIF with location.
Alternatively, you can use Lightroom for this task (4.0+), it will also geocode (provide address for lat/long coordinates) but it won't update the actual CR2's though, I believe.

The benefits of this method are that you can geotag photos from multiple cams this way and that you can use the track for other purposes. FWIW, you can get the logger to log things like altitude and velocity which make a nice addition to photos shot from airplanes -- not sure if Canon's GPS module does this.

Lenses / Re: Sigma 30mm f/1.4 or Canon 35mm f/2?
« on: August 14, 2012, 03:00:37 AM »
I faced the same choice some three months ago.

I visited a Sigma dealer to try out the 30mm f/2 on my camera (7D but I also have a 40D). In a nutshell: I liked the quality of the photos very much WHEN THEY WERE SHARP. Sigma's AF struggles on Canon bodies -- it is OK-ish in bright light but can get really bad otherwise. With most Canon lenses, on peripheral AF sensors, when there's not so much light, at least on xxD / 7D -- it takes time and I need to press the AF-ON button a few times to get focus but I usually do get it. With Sigma, I feel it's worse, there's times when it never focuses correctly (it misses by a tiny bit but it is too much for my purposes, I need the lens to make photos of a newborn baby, eyes must be tack sharp)

I got the 35mm f/2 instead and I am very happy with it. I also very much like the close focusing distance -- again, very useful for newborn closeups.

AF on the 35mm f/2 is loud and not fast (not really slow, but slower than that of 85mm f/1.8 or 400mm f/5.6) but precise.

I really could use Sigma's extra 5mm width so I had also considered the 28mm f/1.8 but ultimately decided against it. I felt the 35mm f/2 had marginally better opinions but most of all, 35mm f/2 was half of the price of 28mm f/1.8 and 30mm f/1.4. This was the money I was willing to risk (and I am very happy with the results of this gamble).
