Hi guys. I recently hopped into the world of medium format, upgrading from my 1Ds III and 5Ds to a 645DF and a P65+. I've purchased the Mamiya Sekor 28mm f/4.5 D, the 80mm f/2.8 LS, the 75-150mm f/4.5 D, the 24mm f/4 fisheye, and the 55-110mm. One of these does not belong with the rest. . . can you guess which it is?
The 55-110mm is awful. Contrast and sharpness are lackluster. I've tried it a few times, but due to the abysmal results, I found myself quickly looking for a better replacement. Late-night Google-searching brought me to the 45-90mm f/4.5 D. Now, there seems to be a fair bit of ambiguity concerning this lens. . . was it actually made? And, if so, how is the performance? I'm looking for something that's of similar performance to the 75-150mm.
On a different note, I'd like to mention specific modifications I've made, or have in mind. First, as an avid hiker (prone to spend days away from a wall socket), I realized the stock 2500 mAh batteries were not up-to-standard for my purposes. There are many batteries that share the same slide rails and terminals, but are restricted by the curved sidewall of the battery compartment on the P65+. Thus, a compromise was necessary.
I ordered four, 7500 mAh batteries from Amazon, and figured, "what the hell, I'll make this work." Some thinking and some creative cutting with my multitool, and I was able to notch a groove into the side of the batteries wide enough to accommodate the curve of the DB's battery compartment. Sweet. I now use 7500 mAh batteries (not so ergonomic, however).
Second thought, I've yet to attempt, as it will actually require physical modification of something a bit more pricey. There's another thread around about outfitting the 28mm lens with Lee grads. Well, really, I think what we all know is that damn metal shroud has to go. With that said, the plan is to remove the shroud, then fashion a mount for the filter holder. Yes, I do realize the lens is quite bulbous, and this could still prove to be a tedious task. Any suggestions, thoughts here? You know, other than, "the 28mm is expensive, you are insane."
Back to the original topic -- the 45-90mm f/4.5 D. Information regarding this lens would be appreciated.
