Originally posted by nater I'd call it entry-level because from a construction standpoint because the metal parts are forged aluminum. Mid-range to high grade in my mind means magnesium alloys and/or CNC machining from solid metal blocks rather than forging.
If the metal components were the likely breakage points of the tripod, obsessing about this would make more sense. :P
Originally posted by nater I've noticed that Dolica has a lot of entry-level, very inexpensive tripods. I assume like many companies, they are re-branding tripods made by one of the big Chinese companies
Yes and the tripod I own (proline 62, 40$) is physically identical to an Induro model (140$), down to the head itself.
Originally posted by nater All indications are that the Field Optics Research Schonfeld KF6615T carbon fiber tripod, which sells for $199 from the Field Optics Research website or $149 from B&H, is the same tripod as the AmazonBasics 52-inch carbon fiber travel tripod, which sells for $79 with ball head.
To continue with my Dolica example, the Induro has straight legs, and the Dolica's legs are twisted so that when they are extended and gathered together, they look warped. They still hold gear steady, but there are differences between apparently identical tripods.
Originally posted by nater I think it's more complicated than "you get what you pay for".
That's your call. Almost everyone gives the same advice.
Originally posted by nater objectively test tripods to see how they actually perform
The best way to test a tripod is to take pictures, which Alex has done.
Originally posted by nater The lack of failure cases actually made it harder for me to determine just how good the Sirui T-025X is.
It tells you that in a set of given (and extremely varied) conditions, it performed well.
Originally posted by nater Let me be clear - your review was good. Most reviews of photo equipment are terrible. But there is room and opportunity for reviews to be great.
I will say this bluntly, but respectfully : I think it is a pretty arrogant way to talk. Writing a review is extremely involved and much more complex than what most people would guess. The reviews posted at Pentaxforums are among the most involved and detailed you will find anywhere on the web, for cameras, lenses and accessories. We spend dozens of hours performing a review, writing it, balancing our opinions with fellow reviewers, being as honest and unbiased as possible. A Photozone lens review covers 3 pages (I respect the work of these guys a lot). A Pentaxforums lens review covers usually 14-15 pages. Gear "tests" at websites like SLR Lounge are mostly hidden advertising. Here honest opinions are given, no equipment is perfect, opinions are backed by facts.
There may be more than one way to evaluate a variable, but that doesn't mean the chosen way is bad. For instance the vibration test you refer to is interesting. But just for the sake of the discussion, it does not represent a likely occurrence in the field. Periodical hits with a constant frequency will not happen unless you work next to a jackhammer. The laser tests shows you what to expect with a long and heavy lens in normal conditions. I believe it is a better tests of actual field performances.
Of course all Internet reviews have one specific flaw : they test a single sample, which prevents reviewers to evaluate sample variation and build actual statistical analysis. As an optical designer who performs equipment qualifications for a living, this irks me a lot. But since people mostly test equipment they own, or single samples provided by stores or manufacturers, it's not likely to change. It's up to you to build your own statistical evaluation by reading multiple reviews and user reports.
I realize I'm coming out strongly. This is deliberate. I always try to remain polite and to contribute to this community in a positive way. However I strongly disagree that Alex's review is "good" but not "great". I'll be happy to answer questions and give my opinion again if ever you want it, but let's keep clear of criticizing other people's work on this thread, please.
