小弟用40D，有支Canon 0~22mm，請問邊隻魚眼鏡ok，因為我聽聞D魚眼鏡落左乘1.6後，對角會減少......如果Tokina，SIGMA，Canon，TAMRON有咩好介紹？？

Canon, no 180deg view for APS-C just 15mm for FF

Sigma, 3 choice
for 40D, 4.5mm circular type fisheye
10mm rectangular type fisheye
8mm rectangular type fisheye for APS-C with a bit black corner

Tokina, 10-17mm support around 176deg view for APS-C (180deg for nikon 1.5X), the only zoom fisheye for Canon (pentax has 10-17 and 17-28 not for canon), T10-17 can be used in FF at 15-17mm as well

Above-mentioned have autofocus

Go for Russian lens if you don't need AF, eg Penleg (not sure the spelling)

#Circular type gives you a circle image with two ends are black
#Rectangular type gives you image fill up the whole frame
(please rectify me if I am wrong, Ching)
