Generally speaking teleconverters do not change minimum focus distances. They simply magnify the center part of the image circle to fill the frame. Since they are taking the light that used to fill a small part of the frame and magnifying it so that is spreads out and covers the entire frame you get less total light at any given f-stop (hence the 1.5 stop loss of aperture).Paul, how would the 1.7x effect the minimum focusing distance of another lens. Like the 100mm? I'm thinking it would behave like an extension tube?
This reminds me of when I bought my 210, which is an ex rental. It had been returned with a broken shutter after a trip to Africa. The same guy had also rented a converter and a 35-90. In the field he had discovered that the 35-90 would not mount on the converter. He then had his assistant try to file down the bajonet, but that did not work out.Are the below combos not recommended because performance might not be optimal or does the body lock you out of using those combos?
The converter 1.7x can be combined with all HC lenses except for the following:
• HC 3.5/35 mm
• HC 3.5-4.5/50-110 mm
• HCD 28 mm
• HCD 4-5.6/35-90 mm
Paul can you elaborate on the below statement?

(this is not a jab; it's a genuine question - we rarely, if ever, get requests for the tele convertor for rental/evaluation so I don't have a lot of hands on experience with it)
Paul has helped me on a few occasions; he is the most knowledgeable Hasselblad person in this hemisphere and his presence on this forum will be an extraordinary plus for us participants.

Is that really the case. The 1.7 converter disables the AF of the HC300. If that's the case then I'm screwedHi,
When the H1.7X converter is used together with the HC Macro 120 mm or the HC300 mm lens, the autofocus function of the camera is disabled.

May I ask why you need AF?Is that really the case. The 1.7 converter disables the AF of the HC300. If that's the case then I'm screwed

I Like AFMay I ask why you need AF?
StanleyI have used two 1.7 teleconverters in front of a 300mm and received good focus results, although with a tripod and mirror up.
But probably not best solution for a safari
