Canon 300 mm f2.8 L II vs. 400 mm f4 DO II

Dear everyone,

I recently switched to Canon equipment for camera and lens. The majority of my photography is wildlife and nature. I initially purchased the 300 mm f2.8 II lens, but now I am wondering if the 400 mm f4 DO II would be a better substitution for the 300 mm lens. I can still return the 300 mm lens since I am within 30 days of purchase.

Advantages of the 300 mm lens:
1) one stop faster at native focal length that the DO lens (should be faster at acquiring focus in low light)
2) more flexible in that i can convert it to a 420 mm f4 or 600 mm f5.6 lens

Advantages of the 400 mm lens:
1) one pound lighter that the 300mm lens + 1.4x extender
2) shorter in length that 300 mm+1.4x extender

In the past I owned a 300 mm f2.8 lens and the majority of the time a 1.4x converter was on the lens, but there were circumstances (birds in flight in low light) where the 300 mm f2.8 had a distinct advantage.

If anyone can please chime in here it would be greatly appreciated.

Thank you,

John

Shutter Shock - help me understand it (anyone seen Cliff or his notes?)

*posted this on DPR in the "open talk" forum as well*

I read through the 5DSr review recently and kind of skipped over the shutter shock section but then while perusing another forum, I found that the topic popped up there too, in regards to Nikon gear.

I don't own any of the gear in question but it seems like the common denominators are shutter speeds of 1/80-1/30 and with longer focal lengths. Also, apparently Canon's in-lens IS apparently alleviates some of the issue as well whereas SOME Nikon lenses with VR actually make it worse.

Historically, it's been thought that lower megapixel FF sensors had less, or even nothing, to worry about with regards to this issue (hence I never bothered to learn about it as I use the 20mp Canon 6D) but apparently the Nikon D750 (24 mp) proves otherwise and actually had worse results than the D810.

Before I go any further - does it seem like I have all of the info correct thus far? If so...

That brings me to my question... with a Canon 6D, the lenses I own which have "longer" focal lengths would be the Canon EF 100mm f/2.8L IS USM, Canon EF 135mm f/2L USM, and Canon EF 70-300mm f/4-5.6L IS USM.

With the 100L, I will often shoot in the 1/50-1/60 range for portraits, thanks to the IS. Thus far, I haven't noticed any issue with it and that's even with pixel peeping at eyelashes (curiosity got the best of me).

With the 135L, I usually aim for 1/160 or higher unless braced or on a tripod so I can't see it being an issue, for ME, with that lens. But it WOULD be nice to know in case I have an isolated circumstance pop up where I'm actually going to mount it on a tripod and shoot slower shutter speeds.

But the 70-300L is a new lens in my arsenal and this is the one I'm most worried about. I literally picked up this lens less than a week ago so I have basically zero experience here. I can absolutely see me using this lens all the way out to 300mm and in the 1/30-1/80 range. Can anyone offer any insight?

I'm not really going to go looking for a problem, but at the same time, if I can avoid (real, not theorized) issues by avoiding 1/30-1/80, then I definitely will.

Thanks for any insight you folks can offer!

Moose on the Loose

Two young fellows showed up in our back yard today. My 5D MK III was out in my studio, so my G1X II had to do the job. I needed a longer focal length, but had to do with a severe crop. I had one shot before they turned away and went out of easy range. His eyes were closed, as he was in the process of shaking snow off.

Wildlife is really hungry this year. We have started buying old bread from our local bread outlet to feed the deer, but we did not expect moose to show up. They also went out to our chicken house to cleanup any left over chicken food. Our chickens were locked in due to the snow.

Power has been out now since last Wednesday, we are running on our backup generator. My router was hosed by the power fluctuations, even though it was on a filter, so I'm on my backup router as well.

Pentax Updates Teaser for New Full Frame Camera

HTML:
<a href="http://www.pentax.com/en/pentaxff/" target="_blank">Pentax</a> has updated their teaser campaign for their upcoming foray into the full frame DSLR world.</p>
<p>In the new teaser, Pentax lets us know about its crop mode feature:</p>
<p><strong>Crop mode with a choice of three settings

</strong>The new PENTAX 35mm full-frame digital SLR camera features a Crop mode, which allows you to select the image size to be recorded, with a choice of three settings: AUTO, FF and APS-C. The AUTO setting automatically selects the appropriate image size for the lens mounted on the camera. It selects either a 35mm full-frame image size for D FA- and FA-series lenses, or an APS-C image size for DA- and DA L-series lenses. The FF setting captures all images in a 35mm full-frame image size, regardless of the lens mounted on the camera.* The APS-C setting captures all images in an APS-C image size, regardless of the lens**, while displaying a cropping frame in the camera’s viewfinder.</p>
<p><em>* In the FF setting, an image outside the APS-C-format picture frame may not be reproduced in sufficient quality with certain lenses and/or in certain situations.</em>

<em>** When an image is cropped to an APS-C image size, the number of recorded pixels is lower, as the pixels in the cropped areas are eliminated.</em></p>

Is this a common problem with the 5D mkIII?

I occasionally get pinkish artifacts on my shots when there is a very bright area next to a darker area. Sometimes it only shows when you magnify the image (as in the Kookaburra photo below - this is cropped from a full frame shot, and then expanded to twice the size to show the problem), but sometimes it is plainly an issue even when not magnified (see the trees photo).

Any hints on what would cause this?

The Kookaburra was taken with an 85mm 1.2L II lens at f 4 and 1/125 sec @ iso 100
The trees were taken with an 85mm 1.2L II lens at f 1.2 and 1/60 sec @ iso 250

Predictions on What to Expect From Canon in 2016

HTML:
<p>I think we’re all waiting eagerly for 2016, as we expect a lot of new consumer, prosumer and professional products from Canon.</p>
<p>Below is what we expect to see from Canon with some predicted specifications.</p>
<p><strong>Canon EOS-1D X Mark II</strong>

This is a no-brainer and we expect this to be the first big product announcement from Canon in 2016.</p>
<p><strong>Predicted specifications:</strong> 20-24mp, ISO 409,000, 15fps, 4K Video, DIGIC 7, More than 61AF Points, Dual CFast, GPS</p>
<p><strong>Canon EOS 5D Mark IV

</strong>We expect to see a brand new version of Canon’s most popular full frame camera soon after the EOS-1D X Mark II, most likely in early Q2 of 2016. The big question with this camera, will it shoot 4K?</p>
<p><strong>Predicted Specifications: </strong>28-32mp, ISO 409,000, 8fps, DIGIC 7, More than 61 AF Points, CF & SD, GPS, Wifi, NFC</p>
<p><strong>Canon EOS 6D Mark II

</strong>Canon’s entry level full frame DSLR is likely to get an update, but we don’t think it’ll come until the end of 2016, perhaps even after Photokina in September. It should be an incremental update to help keep the price down.</p>
<p><strong>Predicted Specifications:</strong> 25mp, 6fps, DIGIC 7, 19 AF Points, SD Card, Wifi, GPS, NFC, Swivel LCD</p>
<p><strong>Canon EOS 80D

</strong>Canon will be updating the EOS 70D some time in the first half of 2016 we think and it should be a decent upgrade for the popular APS-C camera. We don’t expect anything revolutionary, as the EOS 7D Mark II isn’t due for an update anytime soon.</p>
<p><strong>Predicted Specifications: </strong>24mp, 6fps, DIGIC 7, 19 AF Points, SD, Wifi, GPS, NFC, Swivel LCD</p>
<p><strong>Canon EOS M4

</strong>We honestly have no idea what Canon may have up their sleeves for the EOS M4. We do expect a departure from the EOS M3 and someone of a “relaunch” of the system in the first half of 2016. We’re not sure if we’re going to see a full frame mirrorless camera any time during the year.</p>
<p><strong>Predicted Specifications:</strong> 24mp, 10fps, DIGIC 7, A Bazillion AF Points, SD, Wifi, GPS, NFC, Swivel LCD</p>
<p><strong>EF & EF-M Lenses

</strong>We expect to see a lot more new lenses added to the Canon lineup, as 2015 was a pretty good year. Below are the lenses we expect to see in order of most likely to least likely. Again, these are just predictions for the moment.</p>
<ul>
<li>Canon EF 16-35 f/2.8L III</li>
<li>Canon EF 200-600 f/4.5-5.6L IS</li>
<li>An ultrawide Non-L EF zoom</li>
<li>Canon EF 50 f/1.4 USM</li>
<li>Canon EF 600mm f/4 DO IS</li>
<li>Canon EF 85mm f/1.2L III</li>
<li>Canon EF 200 f/2L IS II</li>
<li>Canon EF 800 f/5.6L IS II</li>
</ul>
<p>We also expect to see new EF-M and non L zooms during the year. As always, lenses are the hardest part of the Canon lineup to predict and get information on.</p>
<p>Sound off on the forum.</p>

Advice: have 24/1.4L II, get 35/1.4L II or replace with 24-70/2.8L II?

Happy (Canon) holiday season and leave the socks hanging on the fireplace for Santa is rumored to visit in January with new dSLRs. As mentioned in subject I'm totally baffled if it's better to part with my 24/1.4L II prime and get a 24-70/2.8L II or keep it and get a 35/1.4L II.

I'm shooting landscapes and f/1.4 has proven of no real use to me but I need the best 24mm throughout the aperture range. I have now decided to get a slightly wider than 50mm lens for more flexibility and the new 35/1.4L II is a real temptation, then again f/1.4 is not a priority but all other apertures are. 24/1.4+35/1.4 sound like a perfect quality match. On the other hand, if you've tried is the 24-70/2.8L II comparable from f/2.8 and above and up to 50mm or don't I even bother?

Spain - Special places

Hi everyone!

Over the previous weeks I uploaded the first three parts of my article series about my Trip to Spain. Now I finally came around to finish the fourth and last article.

Aside from the main cities along the Mediterranean coast there are some not as well-known but just as interesting spots that are well worthy of a visit. In this article I’d like to introduce you to some of these, which were among my favorite spots from the trip.

Heres the link: http://focrates.com/articles/spain_2015/spain_2015_part4.html

By the way if you are wondering what happened to part three - I posted it into the animal section since it dealt with the Barbary macaques of Gibraltar.

The link to that article is here: http://focrates.com/articles/spain_2015/spain_2015_part3.html

Greetings and a Merry Christmas!

A New 50mm Lens Mentioned Again [CR2]

HTML:
<p>We’re told that a new 50mm lens will appear in 2016, but we were not told whether it was the EF 50mm f/1.4 or EF 50mm f/1.2L that would be getting the replacement. 2015 saw the release of the EF 50mm f/1.8 STM (<a href="http://www.canonrumors.com/best-worst-releases-from-canon-in-2015/" target="_blank">our favourite Canon product release of the year</a>! Which was a good laugh for some), though most of us were expecting the EF 50mm f/1.4 to get replaced first.</p>
<p>We’re told that an image stabilized 50mm lens is in testing, though no mention of aperture. We’d have a hard time believing Canon would release a stabilized lens faster than f/1.8 for the EF mount, even if it would be unique a product, and probably welcomed by many people. With IS comes added size and added cost, would you be ok with that?</p>
<p>We’d guess the mentioned IS version of a 50mm lens would be for the EF-M mount.</p>
<p>We’d like to see both the f/1.4 and f/1.2L 50mm lenses get a replacement sooner than later. Modern AF and build and perhaps a floating element in the L.</p>

Help please on new lenses

I have a question for anyone who would care to help. I've been thinking about making the switch to FF in the next year and have a question. At what point does one notice the difference between really good zooms and prime lenses? For example, I'd love a 5dsr and would really like a 11-24, 24-70 2.8, and a 70-200 2.8. However, I take a lot of landscape, have no need for quick fps rates, will use a tripod most of the time, and wondered if primes would be seriously that much better. I mean, everywhere I read, the above zooms are stellar, and seem to take a lot of beating. I've even thought of getting a couple of Zeiss otus as I don't mind MF...but...at what point would I really tell the difference? Would I have to produce 2ft. prints to see it, or will there be a marked improvement at A3? Most of my stuff will be at A3 or A2 with the occasional image blown up very large. I used to love shooting with Zeiss in the old days (film) because I could point them straight into the sun and still get flare free stunning images. Any help offered would be greatly appreciated. Thank-you.

Patent: Canon EF 16-40mm f/4

HTML:
<p>A <a href="http://egami.blog.so-net.ne.jp/2015-12-23" target="_blank">patent for a 16-40mm f/4</a> has appeared. This could be a sign that the EF 17-40mm f/4L may be on its way out. We have been told that there was a possibility that the EF 16-35 f/2.8L II replacement could be wider, maybe the information was the EF 17-40 f/4L replacement instead.</p>

</ul>
<p>One thing that stick out to us about this patent is the size of the lens and the fact that it’s not an internal zoom design like the current EF 17-40mm f/4L, the ‘new’ lens is also looks to be larger. Canon has increased the size of a lens recently with the EF 35mm f/1.4L II. The original was 3.4″ inches long and the new one comes in at just over 4.1″ (Canon spec), though it <a href="http://www.the-digital-picture.com/Reviews/Canon-EF-35mm-f-1.4-L-II-USM-Lens.aspx" target="_blank">measures at 4.43″ according to TDP</a>.</p>
<p>There has been a flurry of patent activity on optical formulas lately. We could be in for another good year of new lenses releases.</p>
<p><em>Note: We removed the “L” from our original post, we put it there out of habit. The patent makes no mention of a red ring.</em></p>

Sports shooters: It's a tough life!

I bang up and use my 1Dx's pretty consistently. I noticed I had some AF misses which were unusual at a track meet 12/12. So since I'm a Platinum member for CPS I sent them in explaining the problem.

On 1Dx number 1 the following was found: "Your product has been examined and it was found that the part did not operate properly because the mirror did not operate properly. The part was replaced and product functions were confirmed."

On 1Dx number 2: "AF assembly was out of position causing inaccurate auto focus. Electrical adjustments were carried out on the AF assembly. Product functions were confirmed. Adjusted exposure and ffd, basic focus and shutter speed. Updated firmware. Cleaned C-MOS and checked to all factory specs."

Whew!

At long last, DXO aggregates all lens testing together

Weekes after DXO reported the 5DS R lens testing, the lens test results are finally now in 'gen pop' with the rest of their lens testing in their tables and rankings:

http://www.dxomark.com/lenses#hideAdvancedOptions=false&viewMode=list&yDataType=rankDxo

Joyous DXO magic of note:

  • The sharpest 9 lens + body combos in their database are on the 5DS R, yet only 4 of those cracked the DXO top 10 in their absurd lens ranking system.

  • In the following instances of a 'near identical' lens from Zeiss / Sigma being offered on both the EF or Nikon mount, we have the following wonderful findings:

    Zeiss Otus 55mm
    On Nikon (D800E): Sharpness = 33 P-MPix, Overall Score = 50
    On Canon (5DS R): Sharpness = 37 P-MPix, Overall Score = 46

    Zeiss Otus 85mm
    On Nikon (D800E): Sharpness = 35 P-MPix, Overall Score = 49
    On Canon (5DS R): Sharpness = 41 P-MPix, Overall Score = 47

    Sigma 35mm Art
    On Nikon (D800E): Sharpness = 30 P-MPix, Overall Score = 43
    On Canon (5DS R): Sharpness = 34 P-MPix, Overall Score = 41

    So if the lenses are effectively identical, one would look at the sensor/mount as a root cause for a lower score. I'm sure someone more versant with DXO's pentagon-like level of transparency can explain how sensor-stack-y transmission differences might explain that scoring discrepancy. Or it's just DXO being DXO.

    In fairness, there were some less high profile Sigma / Zeiss lenses that the Canon so comprehensively outresolved the Nikon that even DXO had to give Canon a higher score.
