Iruma AFB on November 3 2009

Blessed with exellent weather, the number of the visitors is reportedly climbing to 1600,000. Indeed, it is a cost-effective answer in this time of recession to the catharsis of good citizen (In Japan, no admission fee is required for air show at AFBs of the Japan Air Self-Defense Force, JASDF). This time I shoot with Nikon digital single-lense reflex camera D70s, which I actually borrowed from my wife today, paired with old manual tele lense
Nikkor*ED 300 mm 1:4.5 (serial# 226570) and monopod. A few images below are shot with AF-S DX Nikkor 55-200 mm autofocus lense (specified in the caption, otherwise shot in manual focus/manual exposure mode with Nikkor 300 mm, 1/1000 shutter-speed priority, exposure adjusted ad libitum checking with monitor screen, actually F 8-11).

"Fan Break" by Blue Impulse 2014 (for enlargement see just below @ Fan Break)

The weather was relatively fovorable, not perfect though. I tried to intrude the Iruma AFB successfully, this time not through the main gate but through backroad on the opposite side of the station (through the platform not from central Tokyo, but from far Saitama).
Landscape in the venue. Visitor: 290,000! according to the official announcement. Cheap recreation for a hospital pathologist, as usual, with no entrance charge and with only local transportation expenses (circa 1000 Yen). This time I shoot with Nikon digital single-lense reflex camera D3000, mainly paired with new AF-S lense Nikkor-S DX Nikkor 55-200 mm (serial #3706760), occasionally with seasoned manual Nikkor*ED 300 mm and cheap compact digital Nikon Coolpix S02.

I, or we, do not drink water since the very morning to suppress the desire to urinate, because of once you got the favorable location for as possible as close of the front line you cannot retreat to urinate and abandon your vantage point!
