Well, I don't know what it is, but it is interesting to look at. It was overcast today, so I will try to go back tomorrow when the sun is supposed to be back. The spider off on the center right is a good 2" across.

Just a reminder that the Canon teleconverters will not work with the macro lenses.

The 100mm macro may not work with a Canon teleconverter, but the 180mm macro does.

Software & Accessories / Canon Close Up Lens and Step-Up rings
« on: August 10, 2013, 08:49:07 AM »
I am wondering how well an "oversized" Close Up Lens works with step-up rings.

As an example, the 100mm L macro and 180mm macro both take different size filters. Step-up rings are relatively inexpensive compared to multiple copies of the Close Up lens 500D.

If I purchased one to fit the 180mm, would there be issues using it + step-up ring on the 100mm?

Thanks

This was taken with the Sigma 150mm macro lens, jpeg straight out of the camera, just resized for posting. 1/400s / f5.0 / iso 4000 handheld.

Edited to add: This is not a crop out of an image.

Since you mentioned that you miss OS with the 180mm macro, try out the Sigma 180mm f/2.8 OS.... I have only read that Sigma 150mm is very good, however I have not read that much about this 180 f/2.8 OS macro from sigma. I could not find either of them at my local lens rental place. If you have the chance try it to see if it performs as well as the Canon 180mm but with OS.....

I rented the Sigma 150mm Macro and I like it. The focal length is a nice fit between the 180 which is sometimes a bit much and the 100 which sometimes seems to be not enough.

It sure seems to lock focus a lot faster than the Canon 180mm macro.



It seems to be quite a bit heavier, too.

It would be nice if they added regular spot AF (like the 7D or 5DIII) to the 1DIV without having to use a lens with a spot AF button on it...

EOS Bodies - For Stills / Re: Avoiding "blown out" reds, how to?
« on: August 03, 2013, 07:44:59 AM »
Neuro has given the practical steps to take, another, obviously, is to shoot RAW, there is often some headway in the RAW file above the histogram that is generated from the preview jpeg that is affected by the picture style choices in camera, even if you are only saving to RAW on your card.

When shooting flowers, a regular source of severe red problems, it really helps to use an X-Rite Color Passport and make some camera profiles, it is very easy to do, especially if you have Lightroom or Photoshop, and will dramatically improve your colour renditions.

Thanks for the tips.

I have to upgrade Photoshop to be able to use it with my camera, or go on the new cloud based system. I haven't taken the time to delve into Lightroom yet- I suppose it is time to do so.

Set your picture style to neutral, display the RGB histogram and ETTR using the red channel.  To take it a step further, you can use UniWB for a more RAW-relevant histogram.

Thanks for the pointers.

I looked a little into the uniWB, and there are conflicting reports as to whether or not it works with the 5D3. Any insights to shorten the learning curve?

I have noticed that images I take of red or close to red or violet things like flowers never seem to work out properly. The red channel on the histogram is always much further to the right than green, blue or the regular histogram.

What are some ways to handle this problem?

Thanks

If you think so highly of third party lenses I must ask you to buy my Tokina ATX28-70 f/2.8 which although very sharp with my EOS1n and EOS620 cameras it is a nice PAPERWEIGHT on my EOS5Dx cameras.
So except for a case where I bought a Zeiss lens 3rd party is not an option. PERIOD.
Everyone who tries to tell me otherwise, they have to buy my nice Tokina paperweight first.

I was lucky to get rid of 2 Sigma lenses in part exchange in a shop.

I had a Tokina ATX 28-80 f/2.8 and it worked just fine on my 5dII and a 1DIV. While the lens worked fine, the images certainly did not stand up to scrutiny. If I chose to view at normal 35mm print sizes (4x6 or so), it would be OK I suppose. I even sent it back to Tokina and all was normal with the lens.

Not the same exact lens as yours and I haven't looked up the release dates of both.

I also own an EOS 620. First real camera I bought, brand new in 1987. I still have it but haven't used it in a long time. Regrettably, I sold off a minty 50mm purchased at the same time a few years ago.

If your 28-70 is from the late 80's, and doesn't work on camera equipment produced in the 2000's, I can't say that I would expect differently.

I am amazed that, for the most part, Canon EF lenses all seem to work with anything made from inception to present day. The exceptions seem to be current IS lenses mounted to early EF film bodies. As I understand it, the EOS 1-V is the only film body that can use all current specification EF lenses.

I would really like to get the Lumia 1020, but in the USA the only carrier option right now is AT&T.

No thanks. Not really a smart move on Nokia's part if they want to sell devices.

I haven't really dug deeply into getting an unlocked version, but so far I haven't found anything definitive that indicates that all features on a US spec unlocked phone (especially LTE) would work on T-Mobile.

I have not been impressed with the iPhones.

The latest top Android offerings from HTC and Samsung both seem to have their issues.

The last new release handset I purchased, the HTC Amaze, burned me with poor bluetooth performance. T-Mobile never corrected the problem and I eventually had to get rid of the phone. I really liked the camera on that phone.

I've been using a Sensation for almost 2 years and right now I'm considering Cyanogen now that there is a stable release and all features work.

I tried Windows phones in the past and still own a HD2, but the MS support there was lacking.

T-Mobile has eliminated the "subsidized" phone pricing so you pay full retail for a new phone. Granted, it is over time and the plan pricing reduction seems to work out to be the same. Even so, these current model smartphones clock in at ~$500 a pop, plus ~$100 a month to use. It's getting to be a bit much and I wish they were more durable.

EOS Bodies / Re: 'Revolutionary' Dual Pixel AF Explained
« on: July 28, 2013, 08:01:24 AM »
Birds in flight, you say? If this video doesn't convince you how fast Dual Pixel PDAF on the 70D is, I don't know what will.  It can track a BIF over a field (2nd video from the top of the page, around the 0:46 mark): http://cweb.canon.jp/eos/lineup/70d/info/af-tech/index.html

After seeing this I'm even more convinced now about this revolutionary tech.  8)


That looks pretty impressive.

I wonder how it would work as a series of still shots instead of a movie.

Does this obsolete the RGB AF focus stuff in the 1DX, if Canon chooses to enable it in firmware for a given camera model?

Looks like there may be some interesting new releases in the near future.

Good point.  Obviously, on a tripod one would usually manually focus with 10x Live View anyway.  But the macro lenses take a hit on AF performance spec - despite being an f/2.8 lens, the 100L IS Macro is in Group C, meaning no f/2.8 high-precision cross points are activated, just the f/5.6 crosses in the middle and the f/4 crosses at the sides (and all of the f/5.6 lines, too).  The 180L Macro is actually in Group G, meaning only 33 of the 61 AF points are active at all, and for cross points just the 15 f/5.6 ones in the middle.

One other thing to note about the 100L vs the 180L is that the 180mm lens takes TCs, meaning instead of 1:1 you can get to 1.4:1 or even 2:1.  With the 1.4x TC, it will still AF in Group G.  With the f/8 AF update, I'm not sure if the 180L + 2X will AF using the center point or not.  While it's physically possible to use a Kenko 1.4x TC on the 100L, there are issues with doing so on the 5DIII - it you have AFMA enabled on the camera, the Kenko 1.4x + 100L reportedly causes the 5DIII to lock up (meaning battery removal to reset).

Would you happen to know how the Sigma f/2.8 150mm or 180mm macro lenses fit in with the Canon AF rules?
