Note:
• In principle, the *istD is compatible with FAJ-series lenses and lenses with the “A” (automatic diaphragm control) position. Lenses without the “A” position can be used without limitation by changing custom function settings.
• Compatibility with built-in flash: O = Usable with filter and without lens hood; Δ = Insufficient brightness at edges and vignetting caused by lens barrel is possible at certain focal lengths; X = Unusable due to poor brightness at edges and vignetting caused by the lens barrel
• For the full lineup of PENTAX’s 35mm SLR interchangeable lenses, please refer to the 35mm SLR Lens List in the Interchangeable Lenses section of this Web site. Consult your local PENTAX customer service center about the compatibility of particular lenses with the *istD.
