I will have to turn on the voice changer for this post. My name is ____ and I am a noctiholic. I purchased this massive piece of glass and am here to reflect on what this life altering (my wife left me with the kids and I lost the house to foreclosure) decision. This is the wildest lens I have ever used. I tried to tell myself that it could pass as a normal lens but realistically there is no way you would want to sling this monster onto your shoulder everyday. I purchased this beauty from poon @ Hong Kong supply and I have blown through more film since that day that I typically expend in 6 months. The lens is really a lot of fun. And I have concluded that there is absolutely no way that you can rationalize this purchase. If you love the fingerprint of this lens there is no substitute. By the same token do not buy this lens unless you already process either a 35 lux/cron or 50 lux/cron. This is the sports car that is way too expensive but you take out of the garage on summer days. When your running it you remember why you bought it in the first place. There is no way to rationalize spending this kind of money on a lens unless your willing to accept that it is an occassional user but one which may very well produce some of your most interesting results. So I hope that these passing words from from one who has succumbed to the Noctilust will prove useful to others of you who have faced the same temptation. Wife, kids, house...all can be replaced... how do you replace the pleasure you can get from wielding a beer keg on the end of your M-7.
