Nikon Announces 2 new FX lenses, the exotic ultra tele AF-S 800mm f/5.6E FL ED VR and the modest AF-S 18-35mm f/3.5-4.5G ED ultra wide zoom.

Neither lens was a complete surprise, the 800mm was spotted by some eagle-eyed connoisseurs back at the London Olympics, and the 18-35mm lens saw its picture and spec list posted on the net many days ago. No word from Nikon if the 800mm monster is part of the Nikkor 80 years celebration theme. The lens will come bundled with a 1.25x tele converter, the AF-S Teleconverter TC800-1.25E ED, designed to work exclusively with the new 800mm lens. I wonder why they didn't incorporate the converter into the lens in the first place. Talking about firsts, the usage of 2 fluorite elements in the 800mm lens is one such feat. . . . read more

Old pops Canon EF300mm f/2.8 IS USM goes to the DXO mark party, ends up with a retirement plaque and a nice watch.

the Canon EF300mm f/2.8L IS USM released in 1999 is long overdue

15 years in lens years, how much does it make in human years? Never mind, the guys in Boulogne-Billancourt are impressed:

"Taking a lens launched in 1999 and testing it against more current models is always going to be an interesting exercise. Fortunately for the EF300mm f/2.8L IS USM, the test data backs up what users have known for years – it really is very good. If you’ve got one and have been considering an upgrade to the Mark II version, you will find improved optical performance, though not by much. The main benefits will be in the reduction in weight (2,550g vs 2,400g) and the . . . read more

Tokina Reflex 300mm MF Macro Lens Review at Ephotozine

Tokina  Reflex 300mm f/6.3 MF MACRO

A 600mm equivalent lens that boasts a constant f6.3 aperture, a diminutive size and mass, and costs just a bit more than a common kit lens? There's got to be a catch, and in this case, quite a few of them, like the issue of image quality:

"Far from being a viable replacement for a more expensive telephoto lens, what we have here is a lens that produces a certain effect, that may be of interest to some. The effect it produces can be used to great effect for the right subject, but can also spoil an otherwise good image.

Tokina  Reflex 300mm f/6.3 MF MACRO

Being a Japanese site, we'll stick to the Google translate version, which is funnier than the actual lens:

"On a sense of resolution, contrast with those.  Not seen, such as coma, such as noticeable, but it is also the lesser limb darkening.  A vivid image of the periphery of the screen as well, is a depiction satisfactory as a mirror lens.  These materials . . . read more

Tokina Reflex 300mm f/6.3 MF Macro Lens hands-on at the Phoblographer

Tokina  Reflex 300mm f/6.3 MF MACRO

"Focusing the lens is fairly simple to do. All you need to do is keep in mind the 600mm focal length (equivalent) and just pay very close attention to your potential subject.

Oh also, it does this really cool doughnut-shaped-bokeh-thinger. That is characteristic of most mirror lenses, and it should be . . . read more

Tokina Reflex 300mm f/6.3 MF Macro Lens hands-on at the Luminous Landscape

Tokina  Reflex 300mm f/6.3 MF MACRO

"I spent an afternoon shooting with the Lumix 100-300mm at 300mm, and comparing results against the Tokina 300mm mirror lens. It was akin to a battle between the halt and lame. The Lumix shows a bit better resolution but also some significant chromatic aberration (purple fringing) while the Tokina has no CA but also lower contrast. The resolution of the . . . read more

Tokina Reflex 300mm f/6.3 MF Macro Lens review by Ivo Freriks: Compact size, limited resolution.

"Shooting with a lens with a focal length of 600 mm (converted to a full-frame sensor) is not easy. Focusing should be done very carefully. Handheld shots with such a lens usually lead to disappointing results. You justmust use a tripod. But even then you should keep in mind that you'll need very clear weather to create sharp images taken from a large . . . read more

Panasonic 100-300/4-5.6 Lumix G Vario review by Ming Thein: Among the blinds, this is the one-eyed king of m43 super tele zoom lenses.

"So what’s the 100-300 useful for? To be honest, I bought it out of curiosity and the lack of a telephoto solution for any of my other systems. It’s actually a pretty good option for reach in a pinch, especially when you’re not sure you’re going to need it – and don’t want to carry around a large 300, 400 or 500mm supertelephoto. The combination of lens and OM-D doesn’t occupy much space in the bag at all. Aside from slightly reduced optical quality and a slower aperture, the biggest . . . read more

Tokina Reflex 300mm f/6.3 MF Macro Lens review at DSLR Magazine.com: Google translated edition.

"Throughout our testing Reflex Tokina 300mm f / 6,3 MF have learned to compensate for the idiosyncrasies taking advantage of what digital photography offers the one hand, and the special modes of the Olympus OM-D on the other: we set characteristic curve making the camera (possible in the OM-D), providing more density in the shadows and brightness and contrast in the lights. With this adjustment, the gain is very important acutance. Of course, each user will know . . . read more

Canon EF 300mm f/2.8L IS II USM review at SLR Gear

"With the price tag of this lens, you would expect top-tier results - and pleasantly, there's no surprise here. On either the sub-frame Canon 7D or the full-frame Canon 1Ds mkIII, we noted excellent results for sharpness from ƒ/2.8 all the way to ƒ/8. At ƒ/11 diffraction limiting starts to set in, but even then there's no

practical impact on sharpness until ƒ/16, where there is a very slight reduction in overall sharpness. . . . read more

Canon EF 400mm f/2.8L IS II USM review at SLR Gear

"Again, results for tolerance to chromatic aberration are excellent, with extremely low testing results. Looking at our sample images, I'm hard-pressed to see any form of color fringing in high-contrast areas.

Shading (''Vignetting'') 
On the sub-frame 7D, there is no corner shading to speak of at all with the 400mm ƒ/2.8 II mounted; on

Panasonic LUMIX G VARIO 100-300mm F4.0-5.6 MEGA O.I.S. Review @ Photography blog

Panasonic LUMIX G VARIO 100-300mm F4.0-5.6 MEGA O.I.S

100-300mm translates to 200-600mm in 35mm equivalent terms. Thats some serious zoom reach.

 

"The LUMIX G VARIO 100-300mm F4.0-5.6 MEGA O.I.S. lens offers virtually silent focusing. In use, we have also found the system surprisingly quick on the DMC-GH2, though not quite as zippy as the GH2 and 14-140mm lens combo. With the focus mode on the Panasonic Lumix DMC-GH2 set to AFC, the lens tracked moving subjects well. . . . read more

Canon EF 400mm f/2.8 L IS USM review at photodo

"Supplied in a blow-moulded case of suitcase proportions this lens leaves you in no doubt of its professional status. The build quality is such that if it was run over by a truck, it might scratch the enameled finish. The tripod collar come carrying handle is of tow ball proportions!

Right in front of the mount is the 52mm drop in filter holder with neat, pinch grip release. The lens then . . . read more

Canon EF 800mm f/5.6L IS USM review at SLR Gear

"The Canon 800mm ƒ/5.6L is the longest lens we've ever tested in the lab, and doing so tested our system to the extreme. That said, there aren't exciting results concerning the sharpness profile of the 800mm ƒ/5.6L, but neither will it disappoint. It's a sharp lens, but not tack-sharp: approximately 2 blur units

between ƒ/5.6 and ƒ/11, and between 2-3 blur units at ƒ/16 or ƒ/22. At ƒ/32 it becomes a bit soft and slightly uneven, at around 5 blur units. . . . read more
