For color film, it is generally suggested to try to use 1 brand of lens manufacturer for the purposes of color consistency from lens to lens. This is in part due to the coatings that are used. If you do not consider lenses only from one manufacturer, I might consider using the Rodenstock lenses with the Schneider lenses since they are similar in color both being from Germany rather than using a Nikon of Fuji lens from Japan in this mix.
I will provide info on lenses in Copal Shutters. The following 150mm lenses in are in Copal 0 shutters. The Rodenstock Apo Sironar N 150mm f5.6 lens is 6 elements in 4 groups with an image circle of 214mm at f22 and weighs 220g. This is a very good performing lens from my experience. This lens uses flint glass. If you can afford it I would consider the Sironar S f5.6 lens with 6 elements in 4 groups with 231mm image circle at f22 and weighs 250g. This is the lens that I have been using for 10 years. Outstanding performer.
The Schneider offerings are more expensive than the Rodenstock Apo Sironar N, but a bit less expensive than the Rodenstock Apo Sironar S. Weights are a bit more than the Rodenstock lenses with just a slight more image circle than the Rodenstock Apo Sironar S.
The Nikon offering may be a little less for the equivalent offering when compared to the Rodenstock Apo Sironar N, but a bit heavier.
If you want inexpensive for the 150mm lens consider the Rodenstock Geronar f 6.3. It only has 3 elements in 3 groups and weighs about 230g. It only has an image circle of 180mm at f 22. The lens will not perform nearly as well and will not have any where near the image circle of the previously mentioned 150mm lenses.
As to the Congo f6.3 Wide Angle 90mm lens it is a much older designed lens with 4 elements in 4 groups. The lens weighs about 175g. This lens has an image circle of only 175mm. You need a minimum of 165mm image circle to barely cover 4" x 5". At best, you will only have about 10mm of movement capability for the camera with the Congo lens at f22??? This would therefore only allow about 5mm of rise or fall! By comparison, the newer designed 6 element in 4 group Rodenstock Grandagon N 90mm f6.8 lens has an image circle of 221mm at f22 and weighs 460g. The Congo takes the unusual 43mm filter size while the Grandagon takes the more common and much larger 67mm thread size. I have the Grandagon and my particular lens is an outstanding performer. There has been some question regarding the quality control of the Congo lenses.
As to the Horseman 2XLF Teleconverter 150-300, the converter with the adapter ring and set screw weighs 230g. The Converter is rather expensive new; it is a 7 element/5 group multicoated design with 1 Extra Low Dispersion Glass element. The image circle is 240mm. An f5.6 150mm lens becomes an f11.0 lens with the converter.
If you prefer the 3 section Gitzo 1227 to the 1228 that is fine. It should be at least as strong but will not collapse quite as much. I don't know the head, Acratech but I believe that it has no tension adjustment for the ball, which is a valuable feature. The maker can claim what they want for holding power. The Linhof Profi II that I have with a Really Rite Stuff Arca Swiss type QR does weigh more at about 641g. This head has proven itself over at least a 10 year period. An alternative to a ball head may be a Manfrotto leveling head. You would have to check the weight of this head however. I would not consider using anything less than the Gitzo 1227 or one step lighter for the camera especially using a 300mm lens on the camera. Also, avoid using the center column of the tripod as much as possible. When using the center column, be very careful.
I used my Linhof Technikardan 45S with an f11 500mm Nikon T (ED glass) lens to take the photo of Moonset, Hallett Peak (http://tinyurl.com/9mljn) on my website. This was difficult, taking the photo between gusts of wind at f32 and 1/8 sec. Any longer an exposure and the moon would have moved through the frame. Photo was taken in 1996 with Provia 100. Needed to use rear tilts on the camera to maintain focus about 1/ 4 mile across Bear Lake to the moon. The photo as a digital 40" x 50" print (printed with the $250,000 Lightjet 5000) is almost as sharp as the 19" x 24" copy. Tripod used was the Gitzo 1228 with Arca B1 Ball (for added mass and holding power than my Linhof Profi II). Photo has been used by Bogen Photo/Gitzo Tripods at Photo Plus East in the Javits Center in NYC and should be on display in the Bogen Corporate Offices in Ramsey, NJ.
Hope some of this additional info proves valuable.
