Pentax K-x White in SeaWorld Part 2

2010-01-20

The first show that our family enjoyed very much in Seaworld of San Diego was the Shamu (Orca or Killer Whale). And it was a bummer that I forgot to take a short video clip which would have recorded our experience with enriched media.

Not knowing about the seating plan and how fast the Killer Whale in a very weted stadium, I changed my zoom lens from Sigma 17-70mm f/2.8-4.5 to Tamron 70-300mm f/4.0-5.6. In hindsight, I may be better off with the Sigma but I don't know. I was totally unprepared for the wet shooting in the shooting. There were three killer whales in the performance and they were superb in the performance as I couldn't see them coming and my zoom setting was always off for the next shot. I zoomed in too much, which I should have kept it around 75mm to 150mm to cover the bigger part of the body.

I was late to the stadium and ended up in the front rows where the Killer Whales performed their splashing scenes with water. It was both fun but way too much for photography. My sweetie had a plastic bag and it was both good and bad. It does the weather proofing for me well but the wrapping of the plastic was bad on my Pentax K-x as they prevented me change setting as I couldn't see the LCD, menu, and others. I would have shot it with AF-C with 5 or 11 points. Instead, I stayed with AF-A with center point throughout. I set for Tv in 1/400 and 1/500 sec.

I get lucky for this one as the Orca comes from nowhere and very fast

As much as I enjoyed the performance, the Seaworld trainers could be cunning. All the simple raincoats costing $8 a piece and all warnings were out for the audience before the show. And to a certain degree, we knew what was coming. And when I saw most of the front rowers gather in blankets and raincoats, my sweetie quickly took out two jackets and a plastic bag for me. She was the best house-keeper for my white K-x as she was rightly concerned about the well-being of my month old white K-x. The plastic bag has saved my K-x and Tamron zoom lens, I think. So much for the weather proofing in K20D or K-7, I certainly wouldn't risk it bare naked in the scene

The show of muscle from the trainer, the beginning of the cunning plot for those audience not prepared to buy $8 raincoat.

Gang of three killer whales lining up for the synchronized splash to the audience. The whales outsmarted all the preparation of human audience in the show. They ran in sync and splash meticulously in 15 to 20 foot gap distance to the audience. They worked as if no one could escape the splash, it was quite amazingly cunning but fun to those who were cheapo like me NOT buying the raincoats and towels from Seaworld. The memorable towels likely cost north of $20. Of course, I had the highest scream of exuberance and admiration on the plot while my boys kept saying "Bad boy and Bad boys, the Shamu" and "No fish for the Shamu".

I was soaking wet on my pant with the splash when the Orca came to my side of the stadium but I was happy and the weather proofing from the plastic bag worked like a charm for me. It would have been better had I prepared for the shooting with AF-C and a better weather proofing idea with transparent covering for the LCD and top mode dials. Shooting a supplemental video would have been perfect to capture the essence in the show.

A real treat for wonderful performance

Impressions & Notes

  • Purple Fringes are very apparent in many of the shots taken while in Seaworld; otherwise, the zoom does fine for me for long shooting in a stadium. A better zoom lens to replace the Tamron zoom will be Pentax DA 55-300mm and I prefer to have the DA instead of DA-L as I can use the quick shift focus in shooting both still pictures and video.
  • I missed the TAv mode in K20D as I can try to remember to set the aperture to avoid the purple fringing with Tamron zoom. Many shots in f/5.6 had the undesirable purple fringes.
  • A video would have been better to complement the experience
  • Plastic wrap works fine with K-x for a one time weather protection but in hindsight, I would have preferred a transparent material so that I can make changes easily in the shooting.

Pentax K-x White in Seaworld Part 1

2010-01-08

If I ever run into a copy of Pentax DA (DA-L) 55-300mm, that will be a great replacement for my Tamron 70-300mm f/4.0-5.6. For all those thinking of K-x, it is best to get the DA-L 18-55 and DA-L 55-300mm combo. But for enthusiast with great interest on video, I will suggest NOT to go for the DA-L lens with 55-300mm. As when I consider the use with video, the AF on video can greatly benefit from quick shift focus. That is after the start of the video recording and quick shift can allow one to adjust the focus manually while a customized button to disable or enable AF will work well in the scheme of quickly manual focusing as in still shot and video.

The AF in video is using the contrast detection. I have not researched into Phase detection and I don't even know if it is supported in K-x to make AF a bit faster. Though contrast detection appears slow, it works reasonably accurate but the AF can't be adjusted right after the start of recording. MF comes into play and quick shift focusing will greatly benefit the shooting if subject moves out of clarity in the shooting. So the DA version (not the DA-L) in 55-300mm or the limited DA will work well in the video.

The purple fringing in the Tamron 70-300mm f/4.0-5.6 is unfortunate. It would have been my better cheapo zoom had it shown less PF on the still pictures in high contrast areas. It takes very reasonable still shots with great sharpness but many of my test shots with K-x are not immune to purple fringing in f/5.6 and f/6.3. I should have attempted higher iso to engage in smaller aperture or use Av mode to have better control on PF

My boys love the show where the otter was the one stealing the money for the soda machine. It is very entertaining show and it goes with a lot of laugh and roar from the audience.

The White Beluga Whale is the next encounter for my visit. It is the gentle creature that you can see it in the kiss. It was a close encounter program in Seaworld and I happen to have Tamron zoom on the shots

The whale flips its body while letting the close encounter students to have individual photo. They should have hired me but my Purple Fringing was quite severe and I failed to get the job until I could upgrade with something better. Aperture in f/6.3. I should have upped the ISO for a smaller aperture

This shot was taken in front of a window and hence the poorer clarity. With a tap on the cheek, the whale will come up for a gentle kiss, that is a real kicker for me to see and take picture.

Impressions & Notes

  • The purple fringing is a bummer with the Tamron zoom; otherwise, it has produced quite a number of great shots with good sharpness for me
  • The Tamron zoom does not have any quick shift focusing. I think in general quick shift focusing in DA (not DA-L) lenses will benefit video recording as it can allow one to adjust for manual focusing after the start of video recording. A current pitfall in k-x video that doesn't AF after the start of video.
  • While I use most with P mode in the trip with K-x, I had to change to Av mode for better leverage on f/8.0 and smaller and push the iso range to fit the shutter speed.
