Since it is a low-end consumer lens I had few real expectations of IQ at 200mm but took a few for reference; I tended to go for something around 150mm to see what IQ it could deliver. I was also looking at shooting around f8 for maximum sharpness, with low ISO's for detail and also to compensate for the movement I also needed to shoot at high speeds if possible. Following the Photo workshop this year (and earlier lessons) I also routinely underexpose by up to 1-step and compensate later. Some results follow:
The first is at 200mm, ISO 160, f8 @1/640th second, -0.7ve: A surprisingly good image , but a little soft with low IQ close-up.
The next is at 135mm, ISO 160, f9@1/250th second, -0.7ve: A noticeable improvement in IQ; quite sharp and surprising for a cheap lens
For comparison I include one using my 90mm+TC taken earlier in the day during a more cloudy period:
ISO 200, f5.6 @1/200th second, -0.3ve: Given that the first lens is generally less than £80 now (tho' by some fluke I managed to find a special offer for around £32 last year
