Because even a 500mm lens is a wide angle lens.

Taken with Takumar 1000/8 with x2 extender and slightly cropped. A large amount of observations and calculations are required to take such shots.

Makes an old K1000/F8 sense over an A400/F5.6 ?

One lens that still intrigues me is the old SMC 1000 mm / F8 but there are almost none reviews out there on a modern FF sensor. On Ebay several pristine K1000's are offered for decent prices.

Two questions are in my mind:

1. In film days cropping was a loss of IQ because of grain in high ISO film. But nowadays digital sensors offer much more flexibility. Would a picture taken on a K1 with such an old K1000 result in better IQ as a cropped picture taken with an A400? Long old tele's no way have 36 MP of resolution I suppose...

2. There is a report this K1000 is very vulnerable for sensor reflection (at least at a Sony A7II). Is there anybody out here who could tell how this lens performs on a K1? #Arkive: CK's Lens Post: Super-Multi-Coated Takumar 1000mm f/8: Adapted Lens Talk Forum: Digital Photography Review

The "hot spot" looks to be the killer.
