I promise, no more light bulbs ;)

I have tried to post an image, to get this thread back to images, but I only get a blank page in response. it´s within the size restrictions, so I don´t know what causes it. Anyone with the same experience?

I had this happen a couple of times recently as well.  Waiting a while or restarting my browser/system seemed to clear it.

Thanks for the confirmation that it is likely the IS.  And dcm, thanks for the link to the Tamron manual.  I always wondered why they included these manuals with products. 

And jrista with regard to the composites, now you are just showing off.  Good work.

Kindest Regards, Lloyd

I suggested VC because the movements look a bit mechanical and  600mm will magnify any movement.  I assumed you have taken moon photos with other lenses in your arsenal and not had a similar experience.  If you have, then this suggests it is the lens.  If not, there are a couple of other things to consider, your base and tripod. 

Were you on solid ground or a deck?  A deck can impart movement from people walking, even if they are inside the house when the deck is attached to the house.  As Neuro noted in some autofocus calibration discussions, his results were affected by movement in the house until he set his tripod on a concrete floor in the basement.

Were you using a lightweight tripod or a tripod with the center column raised?  The slightest of breeze can cause movement in these cases.  These are two other things to consider.

I'll have to try this out when mine arrives.  I haven't experienced anything like this with my 55-250 or 70-200 with extenders.

I seldom read the manuals that come with the product.  I find the best time to read the manual is before I buy it.  Then I have a better idea of what I'm really getting and what to expect.  Still waiting for my Tamron to arrive.

Two more composites:






Wow!  Great composites.

The bad.  Let me know what you think is the cause of this.  It only occurred on the 5diii with the Tamron 150-600.  I don't think the tripod moved this much and I don't think it is from the shutter, but it could be.  Most all of the Tamron ones exhibited this shake when I was taking longer exposures.  The first one is really odd as it duplicated the shaken star all over the frame. The first was a 20 sec exposure and the 2nd was a 3.2 sec exposure.  I had the Tamron version of IS on. I was also using the CamRanger to activate the shutter.  Any thoughts?


Possibly the VC.  Tamron recommends you turn it off when using a tripod or long exposures.  Try again with it off to see if that improves the images.

Hi,
Looks like Canon is pasting feathers on a turkey hoping it will fly.  They ought to lay off the whole group that
worked on this - and then fire the management team that approved it.
    For your info, wild turkey can fly... :P

    Have a nice day.

Yep.  I've seen them perched high in the pine trees at our summer place.  Guess I'll have to get a photo one of these days.

I didn't get out last night to shoot the blood moon. I appreciate the photos I've seen so far.  Glad I have a few more chances coming up.

Here's one I took last month for practice using the M and 55-250 STM on a tripod at 250mm with manual focus and manual exposure.  Its a 100% crop of an OOC image at ISO 100, f/11, 1/90, Daylight WB.  I believe I spot metered off the moon to get in the ballpark, then dialed it in with manual and did some exposure bracketing.

Don't normally mount my EF lenses on the M, but this seems to be one case it does make sense.  I plan to try the 70-200 f/4 with 1.4xIII and 2xIII one of these nights.  Or the Tamron 150-600 when it arrives.  I probably would have been out there if the Tamron had already arrived.

Hi there!

I use this lens since two Years and I like it very much. It's a great lens particularly for architectural shots.
I add some images made with my Sigma 12-24 II on an Canon EOS5D Mark III (all Images shot in Germany):

The last one seems a bit Escher-eque.

i cant wait to try it on the 11-22 since its got IS it might be a tad better than the 22 for macro

Didn't get around to using that yet, other that a quick bench test at my desk to shoot the wallpaper pattern.  The IS should help, but that will be offset by the loss of 2.5 of stops.  The working distance will still be around an inch with the 16mm extension tube, half an inch with 26mm of extension tubes for 1.39x magnification, or an inch and a half with the 10mm extension tube for 0.66x magnification. It should be interesting.

and the last.  Not my first choice for macrophotography considering I have the 100L and 6D.  But in my pack, on the trail, with the M, it might do nicely for wildflowers with the EF-M lenses.

Tried the EF-M 18-55 zoom on the M with the 26mm of extension tubes today - increases magnification from 0.25x to 0.72x.  IS and more working distance help.  Here's some OOC JPGs.

It's often easier to do these things in arcseconds. 

...

Yes, definitely arcseconds. Couldn't agree more.

Wizardry alert. :)

I obviously haven't made the jump into Astrophotography yet  ???

Angles are easier because the sky, for all intents and purposes, is the inner curved surface of a perfect sphere, and measured in degrees for the celestial coordinate system (Right Ascension and Declination) and, therefor, arcminutes and arcseconds naturally apply. ;)

I agree.  I just wasn't sure the OP was ready for that level of discussion so I thought I'd keep it simpler.  Occupational hazard - I'm an engineer and often communicate with others that don't have the same level of technical knowledge so I  tend to simplify things.   ;D

BTW: I'm in northern Colorado.  Maybe our paths will cross someday.
