port needs CAM_ND_SET_AV_VALUE for quick.

get_zoom_steps should be 101.
maybe main.c (Ixus170, same lens) :
// same number of zoom steps as in ixus160
#define NUM_FL 101
#define NUM_DATA 2
extern int focus_len_table[NUM_FL*NUM_DATA];
// Conversion factor lens FL --> 35mm equiv
// lens 35mm CF
// ---- ---- --
// 4.5 25 (25/4.5) * 18 = 100 (min FL)
// 54 300 (300/54) * 18 = 100 (max FL)
#define CF_EFL 100
#define CF_EFL_DIV 18
(& I would prefere Wifi as alt_key.)
raw & video seem good. (Not tested all modes yet)
Edit: "set CAM_MARKET_ISO_BASE=200"
Edit2: US-B-remote & sync fine.

Who feels good for ptp tests? I´m troubled by W-X

& US-A.
