Fallacy

1. Things that Ken Rockwell say should be taken as gospel
2. Being a moderator at Ausphotography makes you a good photographer
3. If you can't afford a Nikon, you should buy a Pentax. In reality, if you can't afford a Nikon, then you should buy a Canon, if you can't afford a Canon, then you should buy an Olympus, if you can't afford an Olympus, you should buy a Pentax

Fact

1. Pentax make a good weight tool for tripods they call a DSLR. Putting a number of them in a canvas bag can be useful for holding down your tripod in windy conditions while you mount a real camera (Nikon or Canon) on the tripod.
