Pocket Wizard Flex TT1

Although I’ve owned these little fellows for more than a year, I never used them for a wedding or for any kind of job.

Why? Because I didn’t trust the TTL functionality. In the past I noticed I was having erratic results when using light modifiers. I think what actually happened is that the pre-flash (which is needed for TTL measuring) wasn’t strong enough and weakened by the shoot-through umbrella or softbox. Using the speedlight without any light modifier would give me good results but that’s not what I was looking after and I could have used normal Pocket Wizards Plus for this kind of job. So my two TT5 and one TT1 ended their “early” carreer in a drawer of my desk.

Fortunately, a few weeks ago I read on PW’s website that a new firmware (v5.000) had been released with the following features:

1) Automatic camera detection

2) Optimized HSS Crossover Auto detect

3) Rear curtain sync

4) Pre-flash boost mode.

Even if all four features sounded interesting the last one looked like the answer to my problem. So I downloaded the new firmware and intalled the utility to make the upgrade.

I arranged a photo session with Carla and David to try this new firmware and we headed to the “Abbaye de la Cambre” for some couple shots.

Here are the results, taken with combo Canon 1DmarkIII and Canon EF 70-200 f/2.8 USM IS on one hand and Pocket Wizard TT5 + Canon 580EXII + softbox on the other side:

As you can notice from the EXIF files, the shutter speeds from these two pictures were respectively 1/800 sec and 1/500 sec. This is more than the sync speed allowed by the camera (1/300). This is IMHO a great feature which allows you to get shallow DOF (due to the aperture of f/2.8) even in great daylight.

Conclusion: As you can see, the results are stunning and I’m now happy with these Pocket Wizards, I think they’ll be useful for weddings, events and other things that I shoot a lot. Their retirement is now over and they are now more than welcome in my camera bag. :D

This test is made for pixel peapers and for people like me who want to buy a TS-E lens for a bargain.

The question is: how good/bad is the Canon EF TS-E 24mm f/3.5 Lcompared to my standards @24mm which are:

  • Canon EF 24mm f/1.4 L II
  • Canon EF 24-70mm f/2.8 L
  • Canon EF 16-35mm f/2.8 L I

The contest:

I took a tripod and put all four lenses in manual mode, shooting my bookcase. Took the picture by using liveview 10x when I thought the image looked the best. There might of course be some user error although I doubt about it since the results seem “locical”.

24mm contest

The results:

  1. @ f/2.8 (results in large HERE). Winner to loser: 24LII – 24-70L – 16-35L. In the center, no big surprise here, since 24LII is already stopped down while the two others are used wide open. In the corners, I’m more surprised. While 16-35 is soft, I don’t see any difference between 24LII and 24-70 which surprises me. I get the same results when I compare the images from the bottom left corner.
  2. @ f/3.5 (results in large HERE). The results here are more complicated here. In the center, I almost can’t see any difference between 24LII – 24-70L and 16-35L. I’m surprised for many reasons. First, I thought my 24LII would be sharper and I can se a huge difference between f/2.8 and f/3.5 for the 16-35L which becomes much sharper. The real difference here is that CA’s (=chromatic aberrations) are much better controlled with the 24LII. The TS-E is softer than the three others. In the corners, almost same story, 24LII and 24-70L are much better than 24TS-E and 16-35L which look soft.
  3. @f/8 (results in large HERE). In the center, I finally get good results with the TS-E lens. Surprisingly, I’d say the winners are 16-35L, then 24LII, then 24TS-E and finally 24-70L. In the corners, I also got a big surprise. The winner (IMHO) is the 16-35L, then (very close) 24LII, 24-70L and finally 24TS-E.

Conclusions:

  1. The Canon EF TS-E 24mm f/3.5 L is certainly not a sharp lens. It’s soft wide open and get better wide when stopped down but stays behind my other “24mm standard lenses”. It has lots of CA’s too which is annoying.
  2. I honnestly thought my 24LII would be much much better than my zooms. It behaves well and is certainly my best 24mm lens, but in terms of sharpness, I guess in real life I wouldn’t see that much difference.
  3. The Canon EF 24-70 f/2.8 L is a good lens. I hear lots of complain on forums but from what I see, this lens behaves very well for a zoom lens.
  4. The Canon EF 16-35 f/2.8 L I is a strange lens. It looks very soft and disapointing until f/8 where it suddenly becomes a great performer.

I hope this helped some of you making their decision.
