Refreshing a dead LP-E4 with new Cells

I have 3 LP-E4 for my 1Ds III and one of them died completely. So the curious person I am, opened it up. Finding it worked with three 18650 LiIon-Cells, just as expected from its shape. One of the Cells was dead, the other two not that bad for 6 Years old.

So I got three working cells and exchanged them. After putting it back together it was able to be charged again, today I will test how well it behaves in Camera. Three green bars in the Battery menu seem promising:

Here are some Photos for you ;)

Interesting how much electronic is in there, I have looked some of these chips up and there is a micro-controller, a dedicated battery protection chip and some relatively big MOSFETs in there.

Nikon To Announce 24-70 f/2.8 VR, 24 f/1.8, 200-500 f/5.6 VR

http://nikonrumors.com/2015/07/29/first-pictures-of-nikon-24mm-f1-8g-24-70mm-f2-8e-vr-and-200-500mm-f5-6e-lenses-leaked-online.aspx/#more-95504


Now this is very interesting. We'll have to see how it performs, but this could be Nikon's first good Budget Telephoto option.
And man what a way to break the trend!

Of course IQ could be total crap at 500mm, you never know, but Nikonian Birders are probably vibrating from the anticipation right now.

I have to say, I might be a bit jealous (just a bit. Not too much, more like eating pumpkin pie when the guy beside you has chocolate mousse.)

Nikon Announces 95 Million Nikkor Lenses Produced

HTML:
TOKYO – Nikon Corporation is pleased to announce that total production of NIKKOR lenses*<sup>1</sup> for Nikon interchangeable lens cameras reached ninety-five million in the middle of July, 2015.</p>
<div class="section">
<p>In 1959, Nikon (then Nippon Kogaku K.K.) released the Nikon F, as well as its first NIKKOR lenses for Nikon SLR cameras, including the NIKKOR-S Auto 5cm f/2. The NIKKOR tradition has continued over the many years since those first lenses were released.</p>
<p>Nikon actively releases new NIKKOR lenses that utilize the superior optical technologies it has cultivated over its long history as well as a variety of technologies developed exclusively by Nikon, including its anti-reflection coating, Nano Crystal Coat, PF (Phase Fresnel) lens elements with superior chromatic aberration compensation capability that makes lenses smaller and lighter, fluorite lens elements that offer superior chromatic aberration compensation and make telephoto lenses more compact, and fluorine coat, which effectively repels a variety of contaminants, such as dust and dirt, water, oils, and grease.</p>
<p>Nikon continues its steady success, reaching total lens production—including those produced with expansion of its lineup of interchangeable lenses for Nikon 1, Advanced Camera with Interchangeable Lenses, the first of which was released in October, 2011—of ninety million at the end of October, 2014.</p>
<p>One of Nikon’s lenses released this year is the AF-S NIKKOR 300mm f/4E PF ED VR, released in January, 2015. This fixed focal length telephoto lens, compatible with Nikon FX-format digital SLR cameras, was the first NIKKOR lens for which a PF lens element was adopted. Adoption of the PF lens element made the AF-S NIKKOR 300mm f/4E PF ED VR the world’s lightest lens in its class*<sup>2</sup>. This makes the lens very portable and easy to handle with hand-held shooting, despite the fact that it is a fixed focal length telephoto lens, expanding possibilities for new forms of photographic expression. What’s more, Nikon has recently released the AF-S NIKKOR 500mm f/4E FL ED VR and AF-S, NIKKOR 600mm f/4E FL ED VR, two FX-format compatible super-telephoto lenses with a maximum aperture of f/4 and for which two fluorite lens elements were adopted to significantly reduce their weight, making them the lightest lenses in their respective classes*<sup>3</sup>, as well as the AF-S DX NIKKOR 16-80mm f/2.8-4E ED VR, a high-performance 5x normal zoom lens compatible with the Nikon DX format. Naturally, the latest optical design technologies and Nikon’s exclusive and highly durable fluorine coat were also adopted for these lenses.</p>

<em><span class="marker">*2 </span>Among 300mm fixed focal length (prime) autofocus lenses compatible with FX-format digital SLR cameras and available as of announcement in Jan 6, 2015. Statement based on Nikon research.</em>

Sony RX100 Mark IV - New Review and Fascinating SD Card Info

DPR has published a new review of what could well be the most advanced truly pocketable quality camera there is, the Sony RX100 Mark IV.

What I found most interesting about this review is what they say about the cards that it can take, and how that choice affects the camera performance etc.

Because so many of the RX100 IV's features produce large amounts of data, you can only use all its features if you use specific SD cards. The main limitation isn't just one of speed, it's the size of file that the card can cope with. Only one of the five cards in the picture below allows the full use of the camera's capabilities (and it's not the fastest).

  • Poll Poll
Short Telephoto Lenses

Whats the most popular short telephoto focal distance?

  • 85mm

    Votes: 25 47.2%
  • 100mm

    Votes: 15 28.3%
  • 135mm

    Votes: 13 24.5%

Got into a bit of an argument, would like some ammunition. ;D.

I don't care about the aperture only the focal length. Note the question isn't what is your favourite focal length, it is which one is most popular, that is which one do most photographers have.

Also does anyone know a good Nikon site where I could post the same sort of Poll? I want to try and eliminate brand bias from the answer. The only difference in the question would be that I would use 105mm instead of 100mm.

5DS Output Uncompressed Video on HDMI?

Canon released a firmware update for the 5DM3 that included the ability to output uncompressed video on the HDMI port. Does anyone know if the 5DS outputs uncompressed video? I've wanted an external monitor for occasional use with DSLRs and ran across the Black Magic Design Video Assistant. It is 5" touchscreen monitor and includes video recording in multiple formats to high-speed SDXC cards. Not bad for a $500 product. I'm primarily shooting with a 5DM3 and 5DS right now and was wondering about the 5DS' output. Canon says nothing about it on their US site or in the manual that I can find.

Lensrentals MTFs for telephoto lenses

Lensrentals, whom I much admire, and Brandon, who is clearly very smart, have posted MTFs for telephoto lenses http://www.lensrentals.com/blog/2015/07/supertelephoto-mtf-curves They had to modify their equipment for the longest lenses, 300mm and 400mm and use a lash up. The sagittal and tangential values for the Nikon 400mm f/2.8 VR III E are very perturbing as they are significantly different from each other at the centre of the lens for 20-50 lp/mm. Brandon explains this by the discrepancy being caused by a combination of tilt and decentering, which hasn't averaged out over the five samples. I don't want to push this further on their site, and this thread might be a more suitable forum.

Lensfreaks have published data from the Hasselblad factory equipment on the Canon 300mm f/2.8 II that the MTFs for 20 lp/mm are close to flat (~0.92-0.88) as are those at 30 lp/mm (~0.82-0.75) http://www.lensfreaks.com/lens-reviews/canon/canon-ef-300mm-f28-l-is-ii-usm-review-a-nice-little-beast/ which disagree with those from lensrentals, which have serious downward curves for 20 and 30 lp/mm. OK, Hasselblad measured only one and lensrentals several more than five, but the discrepancy is huge. However, I have spent 50 years as a scientist staring at data from very expensive equipment that has been pushed to the limit, and I worry about discrepancies and surprising results - a paranoia that has kept me in good stead and kept my measurements relatively clean of error.

Testing out some uncommon infrared lenses

Recently I received my 6D back from LifePixel converted to infrared (OK, 590nm - so purists won't consider this true infrared) and I decided to try out a few more uncommon lenses to see how well they handled.

Below are a few of the photos, but here are my rough findings.

200-400/1.4x I had problems getting AF to catch, so I had to use MF. Not really a big deal. The lens seems to handle fine and I used this for the heron shot below.

MP-E 65 The jury is still out in terms of diffraction. It seems like it might be a bit worse but my MT-24EX ran out of batteries before I could stress it out much. The ant shot below is with this combo.

100/2.8 IS Macro This lens handled fine. However, this is one lens I have used with an unconverted camera + 720nm filter and with that combo I saw banding except at apertures 2.8-4. I'm not sure if this is an artifact with the longer exposures or with the infrared bandwidth, but at 590nm I am not seeing problems. The bee below is with this combo.

70-200/2.8 II This is another lens that performs poorly with a 720nm filter, but performed fine with the 590nm 6D.

24-70/2.8 II Similar to the 70-200/2.8 II. Works fine with the 590nm converted 6D, but just OK with the 720nm filter. In particular there is extreme flaring if the lens is pointed anywhere near the sun (which does not happen in visible light). Note that I have yet to test the converted 6D with the sun in the shot.

8-15 fisheye Works fine with the converted 6D. Of course I cannot test with the filter.

11-24 Works fine with the 590nm 6D. Could not test with the filter.

16-35/4 IS Have not tested yet with the 590nm 6D, but I doubt there will be any problems. This is one of the few lenses that works without issues with the 720nm filter.

TS-E 24 II With the 720nm filter this lens works fine as long as I don't shift it. I haven't tested it with the converted 6D yet.

I also have a TS-E 90 and TS-E 17 that I have yet to test.

Tried out some Zeiss lenses this week (has turned into a focus screen thread)

I am extremely impressed. More so blown away by the image quality; the ability to blow images up to 200-300% looks a lot better on the two i used (21mm and 85mm) than any canon lenses I've used before.

Pros:
Image quality
Sharpness
Lighter weight

Cons:
No AF; was a little difficult to focus through the viewfinder (I'm assuming this would be easier with a Film body?)

Overall...they're worth it if you're not shooting sports.

What lenses have you used that have stood out as super clear and sharp?

EOS 5DS Live view

I have some very specific questions on the live view functionality of the 5DS that I am hoping someone with a 5DS can answer for me.

1) Can you view the image on the PC without any camera menus?
2) Any idea on the frame rate sent to the PC? I assume live view uses a fixed HD resolution?
3) Can you crop the cameras image before it is sent it to the PC and if so by how much?
4) If you can crop the image, is there any means of selecting the area that is cropped before it is sent to the PC?

I know there are all strange questions but my hope is with the hi resolution sensor I might be able to digitally zoom around the image with a PC and use the setup as a sort of low magnification microscope. From doing some calculations with the sensors resolution and a 100mm Marco lens, I know the camera would be perfect for my needs IF the cameras firmware will allow it.

Thanks very much for any relative information.

Another Sigma ART Lens Coming in 2015? [CR1]

HTML:
We’re told that Sigma will announce at least one more ART series lens in 2015. It’s expected we’re going to see an 85mm f/1.4 ART at some point, as well as an ultra wide ART zoom.</p>
<p>Availability may not come until 2016, but Sigma will continue down their aggressive product development cycle.</p>
<p>Their most recent lens, the 24-35mm f/2 ART has been met with a mix of feelings, but all the early reviews say it is continuing the ART series level of performance.</p>
<p>More to come…</p>
