If you use mainly UV filter for colour photos, then you could try this solution to tailor-fit other brands¡¦ hood to the existing C/Y lenses which induce least weight to your system (each hood at 15 to 20g) and also keep the system compact in size. I used ¡§Minotla¡¦s hood AF 2/24mm¡¨ for my D2.8/25mm as it matches very close for the lens. As for D2.8/28mm, it could use the AF 2/28mm hood from Minolta.
Procedures as follows: - It needs to use file to scrape the inside of the hood until it could allow the 55mm filter to pass through from the hood inside. Don¡¦t scrape too much, as a too loose fit will be unable to apply an effective epoxy adhesive. For cosmetic touch up and also as a seal to prevent adhesive squeezing during cement stage, it requires to make a 0.3mm thick plastic ring (outer diameter 65mm, inner diameter 56mm), which is cut from a 0.3mm white plastic sheet and spray to black. The ring is then sandwiched tightly between the filter and the lens. Then apply just adequate slow-setting epoxy adhesive to the scraped portion of the hood and the filter and also some to the back of the hood and then slip it onto the filter until it rest at the plastic ring position. The filter glass would require to be covered by paper for temporary protection. The lens was then positioned with the rear side facing up to further avoid the excess epoxy adhesive to flow down the lens screw. Thereafter leave it for 1 hour for the epoxy adhesive to set and 12 hours for developing full strength. The completed hood set will bind permanently with the filter and cannot be separated. For wide angle lens hood with cross-star shape, it needs to calibrate the correct vertical position of the hood. (Warning: if epoxy squeeze into the lens screw, it would be unable to unscrew the filter after full setting of the epoxy. After necessary position calibration, I actually covered one more spare 55mm filter in front of the lens during cement stage).
