All test shots are done in bright mode with the wrong adjustment on +2 to contrast and saturation and hence the high contrast and saturation on the test shots.
I am quite happy with the purchase and the lens perform well for me especially for the longer range that I can use in the zoo. It will compete with my Pentax DA 50-200 for sure. Purple fringing are seen in a couple of shots with high contrast and I am told to use a smaller aperture to minimize purple fringe with this lens.
Impressions & Notes:
- An absolute bargain to buy this consumer tele zoom lens. I bought mine used for about $90 and I have a great liking for the great value that this lens brings to my amateur photos
- The best thing about this zoom is Sharp pictures.
- Color and contrast are reasonable to good in my experience
- Sharpness, color and contrast can fair well compared to Pentax DA 50-200 in the same range
- Lens is lightweight and very portable as a walk around zoom. That is right, I can use this long zoom for hiking and walk around, very similar to the style of photos that I do with Pentax DA 50-200 f/4.0-5.6 and don't feel the burden to change lens
- Besides sharpness, the next best thing about this lens is the 1:2 close focusing capability. Close up on flowers and bugs are well beyond the $90 calls for. Some of my close up with this lens compete well with my prime macro lens with the similar 1:2 magnification
- Close focus or Macro works in the range of 180mm to 300mm with a switch.
- Since minimum focusing distance is about three feet, this zoom works well with bugs in giving an ample distance farther away from bug.
- Portraits with this zoom is surprisingly well
- The biggest gripe is on more occurrences with PF/CA. My copy is no exception but I used the following to guard against PF/CA
- PF/CA happens more often in bigger aperture as in f/5.6 in 300mm
- I use f/8.0 as the guiding aperture to go agains PF/CA
- I use higher ISO to make up the light for wide open aperture
- I pay attention to high contrast areas as in backlit branches, I change angles for multiple shots
- PF/CA happen worse and lot more often with Tamron 1.4x TC unfortunately
- Overall I am very satisfied with this inexpensive zoom and I push it to its limits with use of TC to reach up to 420mm and 510mm with Tamron 1.4x TC and Promaster 1.7x TC.
- Sometimes I do struggle in collapsing the lens from Macro. What I do is to switch to manual focus (MF) and turn the focusing ring pass the 'Macro distance' in the long end and retract the zoom to normal zoom position. And then I change from MF back to AF.C for next shooting.
- A high value lens in my book for recommendation with only caveat on PF/CA
