Sony TRV22 - first light

Recommended Posts

I got my Sony TRV22 in the mail the other day and tonight I fired it up for a couple of very simple tests.

The first most basic test was to find out how different wide angle lenses would look on it.

I overlayed my aiming reticule over it so that I'd be certain I was consistantly aiming at the same spot on the wall.

TRV22-.JPG is the camera without a wide angle lens.
TRV22-s6.JPG is the camera with a Sony 0.6 that I normally use.
TRV22-t45 is the camera with a Titanium 0.45.

You'll notice that the Sony 0.6 is much wider than the Titanium 0.45! This is also true when these same lenses were used on my old TRV10 and TRV8.

Oh, BTW, I picked up the TRV22 by shopping prices at cnet.com.

The price I paid for one last week was about $630 which included shipping.

Interesting. Thanks for sharing.

Looks like your TRV10 and new TRV22 have the same dimension of view, though. Nice.

Cool artwork....

However, who picked your pink curtains???!!!!

Thanks for the demo....


I use a Sony .6 for Tandems/RW and anything outside. Love it. Especially on tandems. I sit 3 feet in front of Cajones and his student while they do 360's and their bodies fill the frame... then when I dock on the student's hand, I get the face filling the frame with the priceless floppy cheeks and look of excitement.

peace

What do you do with the strap?I looked inside to see what was involved and then took a pair of sissors to it.

If the plane is unrecoverable then exiting is a very very good idea.

What do you do with the strap?



Strapendectomy.

On my old TRV10 I left the strap on because, well, it's handy to have around sometimes but more importantly, the dBox had been designed with the intact strap in mind. It was a beautiful arrangement.

With the new TRV22 and the dBox you can leave the strap on and shove the enitre thing in the box, but it doesn't seem like it sits right (straight) in the box that way. Taking the strap off means that the camera is now pretty loose in the box, so last night I took 64 business cards and used them as shims, 32 on each side of the camera and then gaff taped them to the insides of the dBox for a MUCH better and more predictable and reproduceable fit. The dBox also has a bit of front to back play so I made another shim out of a piece of rubber and gaffed taped that to the inside rear of the box -- again, much better fit.

Tonight's project . . . drilling holes.

Subjectively, it looks a bit better than my 3.5-year-old TRV10, but then again, I would certainly hope so. Although, there really isn't or wasn't all that much room for improvement in the area of consumer single chip NTSC cameras.

I didn't have scads of time this last week and just barely got the TRV22 in the dBox to jump it this weekend. Looked pretty good, slightly different, but when dubbed and viewed back-to-back with TRV10 footage I didn't see all that much difference -- team didn't seem to notice. The view finder is -way- better, but obviously that's not too important for freefall. ;)

Sometime this week I'll borrow a set of resolution and other charts from work and compare the two on a more objective level.

quade,

What, in your admittedly, limited experience jumping the TRV-22 is the best wide angle for it?

Was looking at the examples at the top of the page - and it appears - to my naked eye - that the Sony .6 is a better (wider) angle.

How important is that extra 2 feet of your wall when you're talking about following a formation, or tandem, out the door??

Thanks, in advance!

I still want to look at a couple of different wide angle lenses for the camera.

From what you may have seen in other threads you might already know that different lenses look different on different cameras. Further, the lens designations from one manufacturer do not always match up with the designations from another. Further still, the addition of step up rings for adapting 30mm to 37mm threads and vice-versa can play havoc with the conversion factors and vignetting (dark or even blocked out corners).

As you can see from my examples above, the Sony 0.6 is actually -much- wider than the Titainium 0.45 lens. This was true on my TRV10 and is true on my TRV22. Both the TRV10 and TRV22 appear to be very similar, damn near identical, as far as angle of view on the wide angle lenses.

Historically, I've shot my 4-way teams with the Sony 0.6 lens. The reason for this is that it's fairly important to be able to see all of the grips of a 4-way exit. The better the team you're shooting, the more important this becomes. Less experienced teams have a tendency to hold that first point out of the door for quite awhile in order to get it stable. Experienced teams usually have it stable within a fraction of a second and can therefore key it almost as they leave the door. However, as a camera flyer, if you don't catch that, it doesn't count as a scoring point. In da biznezz, we call that a "J" or "NJ". The judges put up a great big freekin' "J" where the point SHOULD BE and everyone knows it's YOUR fault the team didn't score as high as they could have.

Generally in competition, well Nationals anyway, the top camera flyers will fly with two video cameras. One video camera will usually have a fairly "normal" wide angle lens on it and the other camera will have a wider lens on it.

Last year I shot with the Titainium 0.45 and the Sony 0.6, but because I've been flying closer and I've modified my exit slightly, I've been thinking of getting something wider. (Also, the team just changed their exit count and I'm having trouble nailing the middle of the acceptable window.)

As for tandems . . . I don't do tandems so I can't really tell you, but I've seen all sorts of various stuff on different cameras. Some I think is pretty and some pretty hideous. Just remember though that the tandem passenger is who is paying your slot and that's who you need to see, so, do whatever it takes to make that happen.

Unlike Obi-Quade-Kenobi, I DO do tandems. Early and often. The .3 is too wide. The .5 is fine (Both from Diamond), the Diamond .5 is wider than the Kenko .5 (I posted comparo pictures a while back). With tandems, you have to get low and close enought be able to see the harness chest strap on the student. The students want close, clear video of their expressions and eye movements. Unless you are docked for quite a while with the tandem master, the .3 is generally too wide for that.

Interesting. I'll hold my .3 and my .5 at arm's length and post them. That'll show the differences at "docking" distance.

Thanks for that post, quade...

AWESOME info!!

I understand what you mean with the Tandem clients...so I'll look at that when I start jumping. For now, I just want something to get a good clear shot of what's in the sky with me!

Thanks again!

Ok, I'm a lazy bum.

I took these photos like . . . last week . . . but had them just sitting in my camera until late last night.

Anyway, here's what the TRV22 looks like side by side with the TRV10.

You'll notice the TRV22 is quite a bit shorter front to back, but it's just about the same width from side to side. Height seems pretty close.

One thing that's very clear in this photo is the LCD screen size. Although it was a hassle to do, I could do in-flight debriefs with the TRV10. The TRV22, on the other hand, I think is really too small for this and I don't see how the entire 4-way team would be able to see the image well enough on a single viewing, so in-flight debriefs will be even more of a hassle.

Oh, "in-flight debriefs" . . . that's when you're doing back-to-back loads and the team wants to watch their previous skydive. PITA! Because you have to remove the camera from the dBox, cue it up, let them watch it, re-cue the tape so you don't record over anything important and then put it all back together again and get ready for the next jump. So basically, your break lasts from take-off to 1000 ft. Also pretty risky equipment-wise if you're sitting by the open door.

In regards to the width, do you personally feel that the trv-22 is too wide for sidemount?



Well, first off I'd have to say that I'm biased against side-mounts to begin with so take this with a grain of salt.

I think the TRV22 could be just fine as a side-mount, however, I think it would be awkward to do it without a dBox because of the shape (not flat) surface of the right side of the TRV22.

The dBox from Bonehead solves that issue, but has other issues (including a bit of excess width) that I don't really like too much.

I think for a side-mount camera you might be better served by a PC style camera.
