Obvious pros of the Tair-3S 300 mm f/ 4.5

  • Butt - a convenient thing for mobility, you can go here and there without bothering with a tripod.
  • Very decent sharpness from f/8 onwards.

Cons of the Tair-3S 300 mm f/ 4.5

  • No image stabilizer, so recover your breath and while slowly breathing out, press the  shutter button with exposure and ISO set at min. 500 and 800, respectively (as shooting is possible from f/8 onwards, and with a 2x converter )
  • Considerable CAs, especially, when shooting against the sun. It may be explained by the fact that iris aperture blades are not blackened (though I may be unlucky to have bought a defective lens).
  • The aperture is shut by the trigger. But the shutter button is in the camera, as a result, shooting rate is not high.

Indeed, this is a very big and heavy 'bazooka' lens. Its external appearance should prevent you from using the butt in the city because of a possible reaction of authorities.
