CFi 3.5/100 with convertor 1.4XE or 2XE

[audun_sjoeseth1]

Is CFi 3.5/100 with convertor 1.4XE a good alternative to 150 or

maybe 120 for close portraits, nature details and even landscapes?

How is the image quality with the 1.4XE or 2XE, and which converter

of these gives best result at full aperture with this outstanding

lens?

My view is that converters are a compromise. However, I have both the 1.4XE and the 2XE and find them excellent. They would take the edge off the wonderful 100mm though and there's also the light loss to consider. As far as the converters with the 100mm being similar to a 150mm in quality, in reality I think they would be.

My vote would be to go with the 1.4XE since you will only lose one stop of light as opposed to two (making the lens a 100mmf4.5 as opposed to an f5.5). Something else to consider is that Hasselblad's 1.4X can only be used with lenses with a focal length of 100mm or greater, while the 2X can be used with pretty well all Hasselblad lenses (a limitation if you want to use the converter with the standard 80mm lens). As far as sharpness goes, both converters are capable of producing great results. I find that when I am using the 1.4X, I hardly notice it is even on the lens (a nice bright image), while the 2X makes the image slightly darker and thus a bit harder to focus.

I'll add that if you do get the 2x, you might want to look around for an older Mutar (Zeiss mfg) which seem to be better a better optical performer for the shorter focal lengths (60, 80, 100mm)
