14 55 60 250: Focal lenght comparison with Teleconverter

I wanted to see the difference between all of my lenses in terms of focal length. This is what I thought would best represent them all in one photo. The number stands for the focal length, eg: 14=14mm. The "t" after the focal length means it was taken with my Tamron 1.4 x AF TC (autofocus Teleconverter).
  • SMC Pentax DA 14mm f/2.8 (35mm eq. =21mm)
    • 14mm w/ 1.4 TC =19.6 (35mm eq. =29.4)
  • SMC Pentax DA* 55mm f/1.4 (35mm eq. =82mm)
    • 55mm w/ 1.4 TC =77 (35mm eq. =115.5)
  • SMC Pentax Da* 60-250mm f/4 (35mm eq. =90-375)
    • 60mm w/ 1.4 TC = 84mm (35mm eq. =126mm)
    • 250mm w/1.4 TC= 350 (35mm eq. = 525mm)
Here is my flickr page for the FULL RESOLUTION VERSION
