Bad day with the DSLR’s

Like I’ve done so many times before with my EX1 / 35mm adapter setup I decided to spend today shooting on the north Norfolk coast, only this time I was using two DSLR’s.

I’ve recently picked up a 7D to use as a second body to save me swapping lenses in the field. One of the benefits of the 7D over the 5D is the fact that it can shoot in various frame rates including 1280×720 at 50 or 60 frames a second which can then be slowed down to create slow-mo.

Sylvi trying out the 5D

I love shooting over-cranked at 720p on the EX1 and since shooting for a while on the 5D I’ve really missed slow-mo so I couldn’t wait to get out and shoot some more with the 7D.

I have to say that I’m not very happy with the results, the quality of the images the 7D is capturing is really poor at 1280×720 due to terrible line twitter / aliasing, any areas of sharpness in the shot shimmers and draws your eye to the problem. This is something that happens with the 5D too, but nowhere near as bad as I’m seeing at 720p on the 7D. The noise on the 7D is also different than the 5D, it’s has less visible vertical bands, but also shows more of a dancing type noise pattern. I’ve read a lot that the difference between the 7D and 5D is minor, but to my eyes the difference is huge, especially when shooting in low light with higher ISO.

7D on sticks

I shot of a pair of telephone boxes last night on the 7D, I had the ISO at 640, nothing too high but the shots are unusable due to the extreme noise in parts of the shot. I’m currently transcoding the footage but as soon as it’s done I’ll post some examples of what I’m talking about.

On top of the quality disappointments I also had a Compact Flash card go weird on me. The mac wouldn’t read it, and my Nexto NVS2500 also reported an error and wouldn’t offload it. The weird thing is that the 5D had no trouble reading it at all so in the end I managed to offload the shots by connecting the 5D to the mac via USB and offloading using aperture.

Maybe I just had a bad day, but this has put a big dent in my confidence of the DSLR’s ability to handle commercial projects, I’m glad that none of these 720p shots were essential!

St Tropez trip

I’ve just ordered another DSLR for my trip to St Tropez in the form of a Canon 7D. Now that I own four lovely L series lenses it makes sense to have another body, especially as I’m planning on doing my next Harley event with DSLR’s alone. The plan is to use the 7D with my 70-200 IS lens, the smaller sensor will give me even more reach with that lens. Meanwhile I’ll continue to use the 5D with either the 50mm or one of my wider lenses. Hopefully by May Canon will have released the new firmware with 25p support so I’ll be able to shoot similar framerates with both cameras.

I’ve also had to invest in a bunch of logistical kit for this trip too, I’ll be taking six LP-E6 batteries, two Delkin dual chargers and four 32Gb CF cards – that all adds up to quite an investment! I’ll be backing up as I go to the Nexto DI NVS2500 & USB drives.

Considering the flexibility that this setup offers though it adds a lot of possibilities to my shooting options. I was never able to take my 35mm adapter on one of these jobs before due to weight restrictions for the flights, I’m looking forward to having more creative options with this rig than I’ve had previously though, and all in a lighter package.

Audio wise I’m going to be using my Rode video-mic and Zoom h4n. The Zoom will be used for any interviews requiring better audio than the rode offers and for recording from mixing desks when required.

Support wise I’m still a little undecided. I’m definitely taking my glidetrack shooter which will do the job of shoulder support too, I’ll also be taking a steadicam merlin. Tripod wise I’ll probably have my Miller taken to the event for me because I think it’s going to be too large to take on the bike, I’ll need some kind of support for the ride out there but I’m unsure if I can get away with a normal stills tripod. Will I miss the fluid head or not? Decisions decisions!
