Sigh and you may also have AF and metering issues in red light.  If you are working for the band and they are ok with a light, you can use an LED tactical flashlight to get AF and then turn it off....that is if you have a hard time getting AF in red light or otherwise low light.  Works quite well and some even have a remote pressure switch.

I'm not sure about the polarizer.  The 2 stop loss might not make up any gain.  Might be worth trying though.  Easy enough to swap out on the 300mm.

I'm going to use a deep sky filter.  I got a 2" Deep sky filter took the filter out of the threaded ring and dropped it in place of the UV filter in an extra drop in I got off ebay.  I'll try with and without.  Probably the only thing it might enhance is any ionization tail or coma.  We'll see.  As you noted time is of the essence...no time to fuss around.

I'm wondering if a polarizer would be of any help . I know the max effect is 90 deg to the sun but would it help cut though the low thin haze? I don't want to mess with the mount either, just a tripod. Right now I figure 10-15 min max. 8:00 to 8:15 peak unless it gets really bright :D

Should be an excellent combo.  I will be using the same here and will have an optional 70-200 2.8L IS II just in case I need to go wider.  Not sure how dark the sky will be but I also have an equatorial tracking mount....However it has to be aligned manually and not sure I will have the time to fuss with that before it's set and gone.

I'm going to try over exposing and use the histogram.  Then pull it back down in Photoshop.  Should help reduce the noise at higher ISO's.  Lots of playing to do in a short period of time.

and Uranus right below . I have a "new to me" 300 2.8l is coming Friday that with the 5DIII I'm thinking will give me the framing I want.

Yep it's iffy here as well but at least its possible.  The comet's brightness drops off pretty fast after the 10th so we really only have a few days next week to even have a decent chance at it.  The 12th looks like the BEST photo op due to the crescent moon that will be close to it.

I sure hope to, I've spent the last week scouting for the best view. Just hope the weather holds.

This is what I use...but sparingly and as I mentioned I use a Q-tip and then a dry one to wipe off any excess.  You are not soaking the contact just cleaning the surface.  This is what is used in the aircraft industry for contact reliability.

I have purchased used lenses in the past for cheap.  Supposedly had AF problems.  The contacts were cleaned with this stuff and the AF issues went away.  I've since sold the lenses for more than I paid.  Granted the contacts were in very bad shape but this stuff cleaned them completely.  For most you are better off not touching the contacts at all but there are times when a cleaning is necessary, especially if you notice AF issues or getting strange error messages on your camera.

Comet 2011L4 has been putting on quite a show in the southern hemisphere and next week (3/10/2013) those of us in the northern hemisphere will get a chance.

Please post your comet pictures and let us know what equipment/settings you used.

No grease and nothing else should be on the contacts.  Anything on them will attract dust and dirt eventually leading to AF problems and other issues like error 80.

The only thing to use on the contacts are a high grade contact cleaner specifically formulated for gold contacts and that is plastic safe.  I use a product made by Caig.  Apply it to a q-tip and clean the lens and camera contacts about once per year. 

I would return those tubes and show them to the store manager.  They will take them back but more important is to show them why they are crap so they return them as well.  You will find the canon ones very solid, well built, and grease free.  As usual you pay more but get something that will give you years of trouble free service.

was wondering.  Thought maybe you were using waders with a blind over your head.  Strange things come to mind when we read these posts!  ;)

Love the low angle.  Makes all of the difference.

Thanks,  To get this effect, my Wimberley head is mounted to a board that is fastened to the back seat of my row boat enabling the lens to be about a foot from the surface of the water.  A right angle finder is used so I'm looking down vertically.  I find rotating the boat with an oar an easier method of tracking motion compared to rotating the Wimberley head.   Raising the lens up by even a foot really alters the perspective in a negative way.

EOS Bodies / Re: refurbished 5d III, what do you think?

Maybe not worth it.  If the price is right and you qualify, get the CPS gold membership so at least after 3 months you can get a discount on repairs.

I've always had issues with refurb products (not Canon) so I steer away.  New is not much more usually.

Oh yeah I dont even use the 7D any more.  My images are so much better with the 5DIII even when I crop to make up the APC-C size loss.  The 7D is just a backup now.

Here are the two crops.  The ISO 6400 one could have been exposed more to the right but things were happening fast and well.....  The 1600 one the head was already bleeding past the edge but it worked.  Only a small highlight was blown out.

Overall I'm very happy with the result...though the 6400 one could have been better.

Well, those results, at a pixel level, are much better than the 7D. On a normalized basis the 7D is probably as good as the ISO 1600 result, but the ISO 6400 is just amazing. Thanks for the crops! :)

Lenses / Re: Camera & Lens Focus Calibration
« on: March 04, 2013, 10:32:05 PM »
You need big spaces for long teles.  Vibration will also skew your results.  The longer the focal length the harder it is to get FoCal to give you consistent results.  Ive given up testing any of my lenses longer than 300mm.  I calibrate them manually using a lensalign setup.

New stuff though has come out with the latest version so I might give it a try again when this snow gets out of here.

FoCal takes me less than 10 minutes per test.  I run several tests per lens - distance of 25x and 50x the focal length, zooms tested at both ends and 1-3 intermediate focal lengths (more for higher zoom ratios).  I've done my 600/4 bare and with the 1.4xIII; I haven't done it with the 2xIII yet as I need to find a vacant football field...

600 mm plus 2x at 10x focal length is 12 meters or about 40 feet.  Perhaps a hallway in a house, definitely hard to find a room that big in my house

One of the biggest issues I see with a large mp crop sensor is the diffraction limitations.  Might not be able to get past f5.6 without some loss of sharpness.  I'm cautiously optimistic though.  Even if they kept it at 18mp if they improved on noise and dr then it would be a plus.

AWSPhotography - well if you don't mind a grey-import then UK is not more expensive....

I figure the chances of Pro Canon equipment going wrong within warranty is pretty unlikely, plus all their equipment is made in a handful of locations in Asia. If you want full warranty, fair enough. I've bought three 2nd hand 1D series bodies without issues, so I figure grey import is less risk.

I've used procamera in the uk (no affiliation), and their price compares well to Adorama / B&H / Amazon.

Like you I am considering a 1Dx or MK III, but really want to wait and see if the new bodies have (even) better noise handling (I do nature, travel & landscapes), so need a mix of capabilities....

Unless the new body replaces the 1DX, it's not going to have better noise handling.  No chance, zero.  And of course if it did replace the 1DX, the price.

They certainly could have better noise handling at a low frame rate. FF High ISO IQ is certainly one of the attractions of the 1D X, but frame rate, AF system, and metering system are really more important ones, IMO. I could easily see a megapixel monster getting better IQ, both at high and low ISO along with a DR boost, at a much lower frame rate with a more basic AF system (although not as basic as the 6D).

Right.  But not a 7D Mark II.  It would be a very high-end FF camera to do that.

I don't believe that must be the case. Canon has repeatedly said that they will introduce some "revolutionary" new technology with the 7D II. The 7D line is an inferior line to the 1D X for a multitude of reasons. If the 7D II gets a better sensor, that doesn't invalidate the 1D X. For one, even if Canon manages to increase Q.E. with either a BSI sensor, or maybe a sensor with LighPipe tech, the smaller pixel size will intrinsically limit full well capacity. The 1D X has an FWC of over 90K, while the 7D has 20K. Even if they managed to double the Q.E. of the 7D, and achieve ~40k FWC, the 1D X will still be a superior high ISO sensor, will still have a faster frame rate, will still have a superior AF system, will still have the superior build and greater battery capacity.

Sensor, as I've said in the past, is not the sole factor in determining the quality of a camera. It is one of many, and I would put frame rate as well as AF system ahead of sensor as the primary factors that determine IQ in most cases, except in the few cases where your subject is static (i.e. landscapes.)

By the time you are ready you might have a 7DII available and then you are back to the drawing board on the decision making process.  ;)



If you have choose between these cameras you are very lucky as either one will do fine. :)

Well said, and there are an awful lot of lucky people on here, it seems to me!

Not luck here been busting my bottom for 8 months (still got 3 to go) working 6 day weeks to get this camera.... Which is why it's so important to get it right

(OP) Here is another one but at ISO1000.  1/2500 F8  +1 over meter in full evening sun.

Going to be windy this weekend.  I'd like to push the ISO up beyond 6400 and see how it handles things.  However it's easy to overexpose the head on bald eagles.  Actually some overcast is better in that sense as you get better exposure.
