Build and Handling
The four telephoto lenses had a good quality pro-level built with
a mix of metal and plastic. The Canon EF-S 55-250mm f/4-5.6 IS
STM is lightweight and sleek. On the body there are the AF/MF, and
Image Stabilizer On/Off toggle switches. The zoom ring is pretty
smooth to turn too. The Sony DT 55-200mm F4-5.6 lens is small
but sturdy looking, with only an AF/MF toggle switch on the body. The
zoom ring was not quite smooth to turn, and the focus ring is at the
extreme front of the lens, with no specific marking on it. The Pentax

DA 50-200mm F4-5.6 ED WR was the smallest of all the three lenses,
and had no physical switches or buttons on the body. The zoom ring
on the Pentax was the smoothest and turned very fluidly. The Tamron
AF 18-200mm F/3.5-6.3 Di II VC lens felt strong when held in the
hand. The lens had two toggle switches, AF/MF and Vibration Control
On/Off. The zoom and focus rings were pretty smooth to turn. There
is also a lock key to lock the lens at 18mm. All the lenses weighed over
200 grams, with the Pentax DA 50-200mm F4-5.6 ED WR weighing
the least at 254 grams.
