Software & Accessories / Re: Tripod & Head - $500 or less
« on: March 29, 2014, 08:43:38 PM »
Just spent a couple of weeks backpacking through Sedona, Arizona with the Induro AT-413 tripod and Vanguard SBH-300 ball-head combination. Definitely not a "lightweight" combination (combo is over 8 lbs), but checks off the box for "sturdy as hell" without question (no concerns at all doing time-lapse, night-photography, or long-exposure landscapes).

If you are looking for a lighter option, take a look at the Induro AT-213/214/313, or perhaps even their carbon-fiber counterparts if your budget allows.  Induro makes their own ballheads, but The Vanguard SBH-300 is excellent, and the SBH-250 would be well suited to the smaller induro legs.

Any chance this could be a sign that they plan to transform the M-line into a full-frame system for the US market (with a new name) while maintaining APS-C sized mirrorless compacts for the Eastern markets (where they are better received)?  I would hope that they are holding back on releasing crop-sensor lenses in the US because they intend to deliver full-frame equivalents instead.

You get a TB of total storage space. But you are maxed out at 300MB of uploads a month for the free account. You'll never reach a TB...

I think they have removed monthly 300 MB limit. Its just total 1TB space now.

Awww that's too bad.  I was looking forward to uploading 300MB a month for the next 291 years...

I see the BIF guy, running along the edge of the forest chasing birds!  haha!

Yes...except BIF guy's wife would be the one running with the gimbal, while BIF-guy manipulates the joystick from a lawn-chair.

EOS Bodies - For Stills / Better IQ from 400/5.6L on 7D or 1D3+1.4TC?
« on: March 28, 2013, 01:34:10 PM »
In a focal-length limited situation, would I get better IQ out of a 400/5.6L on a bare 7D (640mm/5.6) or the 1D3 + 1.4TC (728mm/8)? Put another way, would the extra focal length from the 1D3+TC make up for the difference in pixel density from the 7D when cropping is likely required?  I am aware that the 1D3 will only have the central AF point usable in this situation. Will this affect AI-servo performance for BIF significantly enough to minimize any potential gain?

Although this particular setup is for birding, I also shoot gym & field sports. I'm trying to figure out whether it would be worth it to sell the 7D before a rumored replacement actually hits the shelves. Prices for both bodies are only a few hundred away from each other, and I will not be able to afford a 7D2. My current 7D isn't necessarily lacking for me in any obvious way, but I feel that the 1D3 prices are likely as low as they will go, whereas the 7D prices may have farther to fall in light of rumored replacements (70D/7D2). Or would making this switch be a "downgrade" in any relevant departments (video/flash control being irrelevant)?

Thanks for the pic PBD. I looked at similar Induro tripods and although they had removable center columns, there was no simple way of achieving this with them either.  I can live with a center column, but was hoping for the weight savings.  Thanks guys.  I think the Manfrotto 393 and 055XPROB will make a fine match.

Thanks TrumpetPower, I will take a look at the 055XPROB/3021. 

I have seen a couple ads for the 055XB and 055XV models out there on the used market as well.  Am I correct in assuming these have roughly the same specs as well as the capacity to remove the center column so I can thread the gimbal head directly on the tripod?

Also, will the XB have more stability than the XPROB since the former does not have a hinge allowing horizontal positioning?

Software & Accessories / Tripod Legs for Manfrotto 393 Gimbal Head
« on: March 25, 2013, 11:12:37 PM »
Just nabbed a used Manfrotto 393 Heavy Duty Gimbal Head for about $75 shipped. I plan to use it for raptors/nature with a gripped 7D + 400/5.6 lens. I realize that for this setup the gimbal is probably overkill, but I intend to buy/rent the 300mm 2.8L IS II + TCs in the future and figured I'd get some practice in the meantime. 

I need advice on a decent pair of legs to match with the gimbal head that can support a modestly heavy setup. I'd prefer either center-columnless or removable center column, but cannot afford the Gitzo/Feisol/RRS pricepoint.  Are there any options from Manfrotto or Induro under $200 that you would suggest?

Lenses / Re: Need help with choosing a telephoto for $800 and under

If you can part with something you don't need (I don't know what) and swing for the recent 100-300 L IS or veteran 100-400L IS, you will actually see a notable difference in reach from 105mm.

Pretty sure RS2021 is referring to the 70-300L IS lens.  Unfortunately that beauty tends to sell on the used market for $100-200 more than the 100-400L IS, which already sits above your budget by at least that margin.

The two versions of the 200mm f/2.8L are identical optically.  Cosmetically, version 1 has an in-built retractable hood, whereas version 2 lacks a hood (which means you will have to purchase one separately if you require it). It is a great lens, small and inconspicuous (not white) but does feel somewhat long for environmental portraits.

An 85mm lens will frame similarly on full-frame as your nifty-fifty did on the T1i. You would likely feel right at home using either the following on the 5dII:

canon 85/1.8 ($325)
canon 100/2.0 ($350)

I personally prefer the 100/2, but to each their own. That would leave you with enough cash to put towards a telephoto zoom for close wildlife like the:

Tamron 70-300 VC ($275-325)
Canon 70-300 IS ($300-350)
Canon 70-200/4L non-is ($450-500)

I have owned all 3, and quickly sold the Canon 70-300 non-L IS after purchasing the Tamron. Benefits of the f/4L lens over the Tamron: build quality, aperture, autofocus accuracy & speed.  Advantages of the Tamron: focal length, 3-4 stop stabilization, color, cost, included accessories, warranty. 100% pixel peeping at 200mm showed me no discernible difference between these optically using 10xLV.  Although 300mm on the Tamron is not superb, it clears up nicely with a bit of contrast/sharpening in post.

If you are looking for the best single lens for your cash outlay, then the following come to mind:

Sigma 85/1.4 ($750-800)
Canon 135/2.0L ($750-800)
Canon 70-200mm f/4L IS ($850-900)
Canon 200/2.8L + 1.4x extender ($650 + $150)

The included prices are rough used-price estimates. Nice portraits by the way!

If you are looking for an affordable fast prime, I would suggest the Sigma 30mm f/1.4 EX DC HSM. It will frame like a 48mm on an APS-C camera which is as close as you can get to a standard 50mm on crop. A few online retailers have had deals for this lens around the $300 price point. If you are open to buying used, you may be able to pick one up a used one along with a 2nd hand Canon EF 50mm f/1.8 II right at your budget.  A word of caution however.  The Canon 550D/T2i does not have AFMA, so you will need to check that the sample you intend to purchase focuses well on your body.

Alternately, a replacement for the kit zoom (18-55mm IS) would likely serve you better from a versatility standpoint. A fixed-aperture zoom like the Tamron 17-50mm f/2.8 (non-VC) is plenty sharp and will cover the wide-standard range well. Similarly, the VC version of this lens (more expensive) may prove more useful still if you intend on capturing handheld video without nausea-inducing camera-shake.  You may have to do some hunting for the latter option if you want to stay under budget.

Prime Lenses (est. prices)
Canon 35mm f/2.0 non-IS ($300 new, $250 used)
Sigma 30mm f//1.4 ($325 new, $275 used?)
Canon 50mm f/1.8 II ($100 new, $75 used?)

Fixed-Aperture Zoom Lenses
Tamron 17-50mm f/2.8 non-VC ($300-350 used?)
Tamron 17-50mm f/2.8 VC ($350-450 used?)
