About me:

Have had a serious passion for photography all my life. Got my first SLR in high school and first Nikon F in college. Primary interest these days is nature photography, especially birds (stationary and on the wing), macros and landscapes.

On article Battle of the titans: Top ball heads tested (300 comments in total)
In reply to:

TheDman: I'm not sure how a ball head improves my experience. Why would I not want the control of my pan/tilt that came with the tripod?

I shot with a pan/tilt for many years, starting in 1960s, even using one with a view camera for a time in my film days. I really wasn't even aware of ballheads until I read about them while researching carbon fiber tripods about 10 years ago. I instantly adopted them for the easy freedom of movement, not needing the precision and " fussiness" of the pan/tilt. I shoot birds a lot with a 500mm lens and Wimberley Sidekick mounted which works great with a ball head in making quick movements to follow the action of the birds. Having said that, that''s what fits my style. Obviously for you and others, pan/tilt offers more advantages.

Nathaniel George Weir: Why does everyone complain complain complain complain in the comments at DPreview? Seriously this is free information for all of us. If you don’t like how they present the article then just move on about your life. I honestly value the comments section in DPreview, but part of the reason I haven't been coming to DPreview is because I’ve become sick of all of the negative comments and feedback from people who have nothing else better to do or say. I understand that DPreview moderators listen to the people in the comments section. But please people:
“If you don’t have anything nice to say, don’t say it at all"

A little pollyannaish, don't you think? Any review like this needs to be open to criticism. Perhaps you were trying to suggest that criticism should be contructive rather than just overly negative?

tlinn: I clicked on the link to this review as soon as I saw it looking forward to seeing how the Markins and Acratech ball heads stood up to their heavier brethren. Very disappointed to see that they were not included. :( Whether or not the balls are smaller, these manufacturers are typically considered along with the others so their inclusion would have been quite useful.

Agree 100%. I use Markins and Acratech ball heads precisely because of their excellent combination of high performance and lighter weight. To not because of the ball diameter, rather than on their rated load capacity, is a major failing of review.

Not including Acratech and Markins pretty much renders this comparison of "Top Balls" useless, since it leaves out these two major players. The Markins, in particular, is extremely competitive because of its combination of strength and lighter weight. I use it on a Gitzo series 3 tripod with D8xxx and 500mm cameras, 500mm lens, TC and Wimberley Sidekick.

Thanks for your response. I'm still having a hard time pinpointing the location. Perhaps I'm not interpreting the map correctly. :) Anyway, no problem. Heading down there next week from North Carolina.

sh10453: Quite a documentation!!!
Thank you for a very significant historic event.

Let's hope that Trump and company will not repeat such a shameful act.

To Frank C. - About 2 million more popular votes for Clinton than Trump. At best the US is 50-50 on Trump. I share sh10453's hope in that regard. But to the original subject, glad Lange's work on the subject is seeing the light of day.

FuhTeng: Good, first time I've seen a mention of a Tamron-equivalent to the Sigma dock (I haven't kept up with the newer Tamron lenses). I'm intrigued.

So how would a 1.4x TC on this work on my Nikon D7100? I assume it'd work poorly, if at all.

FYI. was just reading the Tamron TC press release and saw this table. The footnote indicates that AF will work when using the 1.4x TC on cameras that offer f/8 autofocus. However, for low contrast/luminosity subjects, images may be out of focus. Will be interested to see how this works out in user testing.

Available focusing mode when used with SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022)
When using viewfinder When using live view mode
With 1.4x teleconverter AF*1*2/MF AF*2/MF
With 2.0x teleconverter MF AF*2/MF

*1 Autofocus functions normally on any camera that offers F/8 autofocusing (see your camera's instruction manual for your camera's ability).
*2 Subjects with low contrast and/or luminosity values can sometimes result in out-of-focus images.

[1]Compatible model is SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022) (As of September 1; Tamron)

Oops. You're right, and so was Kharan. :)

AF should work with the 1.4x TC for those cameras that can AF with a max. f/8 lens opening. I believe the f/6.3 shuts down to about f/7.1 with the 1.4x TC. The 2x would pose a problem, though.

On photo Spinner in the Rear View #2 challenge (8 comments in total)

FYI - I need to make a correction to the Exif data, above. I actually shot this with a Nikon AF-S 300mm f/4 lens with a 1.4x teleconverter and with the camera set on a 1.2x crop. That all adds up to the stated 500mm focal length.

Thanks for the kind remarks. I was thrilled to find this bud in my back yard and grateful I was able to do it justice in photographing it.
