Nikon Loves You All, Rewards You With New Wide-Angle Lenses

Nikon has today announced two new lenses, the AF-S NIKKOR 24mm f/1.4G ED and the AF-S NIKKOR 16-35mm f/4G ED VR. Now, those of you used to Nikon’s nomenclature will already know all this, but for those unsure, the AF-S designation in both of those means they’ll auto-focus on any body, and the lack of “DX” anywhere means these are designed for use on FX (and will still work, albeit with crop factor, on DX). They’re both G series lenses and both use ED and aspherical elements and Nikon’s new nano crystal coating to handle optical phenomenons like diffraction, ghosting, etc…

As those of you with a grasp of modern optics and physics might expect, the 24mm f1.4 is rather chunky, basically a 3.5″ cube and weighing in closer to 1.5 lbs. It’s also not a budget prime, and it’ll enter the market at just under $2,200. The 16-35mm f/4, being a slower aperture zoom, slots in as Nikon’s affordable alternative to the 14-24mm f/2.8 (well, sorta, it’s obviously not apples-to-apples), weighing in at $1,260, or approaching 600 bucks cheaper than it’s bigger bro.

They’re both up on our preorder waitlists, so you should go here and add your name: https://www.robertsimaging.com/preorder.jsp



Canon EOS 7D Gets Honor of “Last Review of the Decade” at DCResource

7dJeff Keller at DCResource has his hands-on, average-joe review of the newest available Canon body up on his site. For those who’ve forgotten or not encountered it yet, the Canon EOS 7D is a new tier of APS-C sensor (1.6x crop) body from Canon, designed to sit above the 50D and below the 1D series, and sit in parallel to the full-frame EOS 5D series. To that end it has quite a few high-end features, including a robust weather-sealed body, 18 megapixels, an all new AF module, a 100% viewfinder, and 3 raw modes.

Does it live up to its billing? The DCResource article is typically hard statement free, leaving you to call your own judgments, but he has no shortage of good things to say for it at the end of the review…



2009 Holiday Shopping Guide: Don’t Sweat the Megapixels

2009-holiday-shopping

Alright, we’re back for round two of useful, practical advise for real people buying real cameras (as opposed to androids buying anything by Fisher-Price, I suppose) this season. Last time we covered Image Stabilization, and why you should love it. This time, we’re going to tackle megapixels.

Megapixels, which define the amount of resolution your pictures will have, have been the big selling point of digital cameras about as long as they’ve existed. The problem is, at this point, it’s a pretty useless number to know. Why? Because probably 90% of you out there don’t need more than6-8 megapixels, and we hit that a couple years ago.

Don’t read me wrong, more megapixels do lead to more resolution, but you have to be using the pictures in certain ways for that to matter. Now, there are a bunch of things that matter here, so this is in no way scientific, but f you want a general guideline for how many megapixels you need, here we go:

1. If you plan to mostly view your pictures on your computer, or maybe print them as 4×6s and the occasional 8×10, and don’t know what cropping is or do it rarely, you really don’t need more than 6 megapixels.Yup, 6. That means that basically every camera on the market right now has enough resolution for what you do. If you see a good deal on a lower resolution camera (like an 8 megapixel Nikon Coolpix S210 for $69.97, maybe), you should jump on it.

Bonus: On smaller cameras, lower megapixels can sometimes mean better color and less noise. Not believing the hype that more megapixels are always better can end in better pictures for you.

2. If you’re an advanced shooter, an artist, a starting pro, or really anyone else who likes the ability to have some room to crop and the ability to print 16×20s without fear, then you only really need between 8 – 12 megapixels. There are people who’ll tell you you can’t do pro work without at least 20 megapixels, they’ve obviously forgotten that five years ago the shots in Sports Illustrated, GQ, Vanity Fair, you name it were done with cameras that at the time had extremely high pixel counts, like 8. 8-12 is in theory enough to print billboards with ease, because you’re going to be viewing them from 50 feet away.

3. Finally, if you do a lot of highly demanding client work, or you like the ability to crop 3/4 of the photo off and still print at 16×20, this is where cameras with 14-24 megapixels will start being what you want. Under normal, casual circumstances most of the pixels won’t matter, but if you’re pushing things to the edge, it might be worth having the extra resolution to back you up.

I bet most of you Christmas shoppers fall into the first category. A lot of our regular customers are probably that second. Point is, don’t get hung up on megapixels, they’re probably one of the least important specs on any camera available today. I promise.

Canon Days: Hands On Review: PowerShot S90

carel struyckenDuring the ’70s, a producer/director friend of mine used to roam the LA punk scene with an amazing little 35mm camera, the Minox 35 GL. It was the smallest 35mm camera ever produced. Its sharp Minotar lens shot beautiful pictures and thanks to the high ISO films that were being perfected in those days, one could shoot in very low light. There has never been any digital equivalent in size and low light capabilities until now, with Canon’s introduction of the S90. With the G11 and S90 cameras, Canon has finally reversed the maddening pixel race. Pixel density on the G11 has been reduced from its predecessor’s 34MP/cm² down to 23MP/cm² and low light performance has greatly improved. The S90 uses the same sensor and its f-2 maximum aperture helps to make this the best p&s for available light shooting.

The Canon S90 is slightly larger than Canon’s Elph (3.5 x 2.2 x 0.8″ for the Canon SD940IS vs. 3.9 x 2.3 x 1.2″ for the Canon S90), but it still easily slips into the average pocket. A bit too slippery sometimes and it almost fell out of my hands before I made it a rule to use the wrist strap. Much has been made of the programmable function control ring around the lens and it is indeed wonderful…

Canon’s EF-S 15-85mm f3.5-5.6 IS USM Meets Good Reviews

Canon EF-S 18-55mm f3.5-5.6 IS USM

Canon EF-S 18-55mm f3.5-5.6 IS USM

Canon’s EF-S 15-85mm, its new lens replacing the venerable 17-85mm, has been reviewed over at SLRGear. With its EF-S designation we know that it’s designed specifically for use on Canon’s 1.6x crop bodies (the Rebels, xxD, and now the 7D cameras.) and has an effective field-of-view equivalent to 24-136mm in film terms. Which makes it a pretty usable zoom, covering most to all of the commonly needed focal lengths.

The review mentions very good sharpness, 1 stop or less vignetting, and no more geometric distortion than can is typical of this class of zoom anyway. Combined with being wider and faster than its predecessor, and the “step-up” features like a distance scale, this lens is a safe recommendation for anyone needing to step up from the 18-55mm but who doesn’t need (or can afford) to dip their toes in the L waters.



Canon’s New EOS-1D Mark IV Gets Real

Rating: 4.0/5 (1 vote cast)

eos-1d-mark-IVCanon this morning in the wee hours when I was decidedly not awake announced their newest pro body, the long-awaited EOS-1D Mark IV. It’s direct predecessor, the Mark III, had just been announced before I hired on here at Roberts, so the announcement of the Mark IV is something of a milestone for me, personally.

Now, getting past the sentimentals, here’s what you need to know:

1. The Mark IV continues the tradition of the 1D line in using an ASP-H sensor with a 1.3x crop factor. The full-frame chips remain a hallmark of the studio-oriented 1Ds line, and of course the 5D series. It’s up now to 16.1 megapixels, and keeps dual-processors (now the DIGIC IV models).

2. It has an all new 45-point autofocus system (39 of which become the more accurate cross-type points with an aperture of f2.8 or wider). Did we  mention it’s all new and reportedly exhaustively field tested?

3. Canon is showing a rare conservative streak, and the continuous shooting mode is throttled back to 10 frames per second (versus the blistering 14 of its predecessor).

4. 1080p video. Really, were you expecting them to leave this out after the 5D Mark II, Rebel T1i, and 7D all got it? If you were, shame on you. If you weren’t, ta-da! HD video for everybody!

5. Expanded ISO. The Mark IV sport an expanded ISO range of 100 – 102,400 (which seems somehow familiar)

Those seem to be the key points, a lot of it is the stock stuff you’d expect from a camera at this price point. It keeps the 3″ 920,000 dot LCD, build, 1/300s EX shutter sync, 100% viewfinder, you get the point. Continuing the trend started with the EOS 7D, Canon’s announced a new wireless file transmitter for this beastie (and one for the 5D Mark II, too), for those of you who dig sending photos straight to a computer.

I shouldn’t have to say Get On Our Wait List Today, but it looks like I just did.



Nikon Coolpix S70: That’s a Good Lens

So, we heard the occasional murmur that Nikon’s last series of Coolpix may or may not have had sharp lenses. Well, we know for certain that’s not the case with the shared 28mm 5x zoom on their new series. We were testing the S1000pj and the S70 today and woah, those suckers have good little lenses for point-and-shoots. Really good. Don’t believe us? We shot the pic below from a magazine in the classroom, with the S70 in macro mode. Check out the detail in that crop, it got the printing ink and the irregularities in the newsprint. Very impressive show, Nikon. Very impressive.



Leica Announces M9, X1 Cameras

Leica, the originator of the 35mm still photography format, announced earlier its newest offerings, the nigh-indestructible M9 rangefinder (replacing the somewhat troubled M8 and M8.2 bodies), and a new digital compact dubbed the X1.

M9-with-sensorThe king of the show (of course) is the M9, sporting a Kodak-designed 18 megapixel full-frame sensor (which solves one problem of its predecessor, which made wide primes behave notably less wide thanks to a crop factor). The sensor once again lacks an anti-aliasing filter, which I hear resulted in insanely sharp photos from the M8s and which meshes well with all expected physics as well. This time Leica has seen fit to put the cut-off filters back over the sensor, removing the sometimes criticized need for a gamut of such filters for your lenses. Bravo, Leica. Combined with the body tweaks done on the M8.2 to solve a few problems with the day-to-day, in-the-warfield use, Leica’s getting its M series very much to a nice zenith for the digital age. Mind you, I think you still have to take the baseplate off to switch memory cards, but there’ll always be trade-offs for award-winning body design, yeah?

x1The other camera, a compact body with a 12.2 megapixel APS-C sensor and a fixed 24mm f2.8 lens (kinda like Sigma’s DP2), brings the clasic M series aesthetic to the compact market, while simultaneously creating a new price tier for digital compacts. It features an available grip, and a built-in flash (which is quite cute and cylindrical), full-manual controls (including aperture and shutter dials), RAW, etc.

Both bodies have decided, in a bold and applaudable move, to forgo in-house software and instead come with Adobe’s Photoshop Lightroom. Bravo, Leica. Seriously. I’ve used quite a few RAW and managements softwares, and Lightroom is easily the best of any of them, and makes taking pictures from good to fabulous a quick and painless chore, complete with robust filtering and organization options. More people could follow Leica’s lead here and I would not be hurt in the least.



Canon’s EOS 7D Gets Real

7dCanon’s new shooter, the 7D, is official now. In a rare event for Canon, this model doesn’t upgrade anything, but slots in as a new option in their line-up. The 7D sits above the 50D but below their 1D series. It retains the 1.6x crop APS-C sensor of their Rebel and xxD series, but pumps in other pro features. It’s crop sensor pro lite, really. It was announced today with a new wireless file transmitter just for the 7D and three new lenses (including a 100mm f2.8 macro which is Canon’s first lens to use their Hybrid IS system, w00t!).

We’ll have more the lenses soon, but for now here are some key specs on this new Canon beast:

  • 18 MP CMOS Sensor
  • Dual DIGIC IV Processors
  • Supports EF and EF-S lenses
  • Magnesium, weather-sealed body
  • Shutter rated to 150,000 actuations
  • An LCD is overlaid on top of the viewfinder to show AF points, composition grids, spot metering, electronic level, and the usual shooting info
  • 3″ 920,000 Dot LCD
  • New 19 Point all Cross-Type AF Sensor
  • New iFCL 63-zone dual layer metering system
  • ISO 100 – 12,800
  • 30 – 1/8000 second shutter speeds, plus bulb
  • 3 RAW sizes
  • Dual-Axis Virtual Level
  • 8 Frames Per Second Continuous Drive
  • Full HD Recording (with manula controls this time)
  • Mic Jack

Should be up on our site very shortly, these new fly-by-night cloak-and-dagger product announcements and embargos make it rough on us poor vendors, since we’re increasingly often finding out these things are official from the same sources you are, leaving us scrambling to get them up

But, while we scramble, hit us up at 1-800-726-5544 if you want on our wait list for the 7D or any of the new lenses.
