You're all for wanting us to critique photos, but hell no don't dare critique what somebody else suggests using as kit. Even if that might stop somebody making a large financial outlay to end up with a lump of very expensive alloy that doesn't do what's wanted or needed. Thats more important than saying "nice photo" or "the shadows could be lightened".
I'm a Mechanical Engineer - I critique machinery and equipment for a living and photographic gear is no different for any other machinery - this is what I do. I don't upload endless quanitities of meaningless photos waiting for somebody to tell me what I already know -to me that's pointless. These days I don't get anything out of this website other than an occassional laugh and a bit of a read, but I give back in terms of almost 40 years of engineering and photographic experience.
In saying this, I seem to be the round peg in the square hole - Rick if you don't like my attitude then say it to me, don't just make generalisations and I shall forthwith terminate my membership its no loss to me. As a public website I don't have to log on and the membership can do without whilst the benefit of looking is still there.
