For those like me who are using lenses that came with screw on caps or caps that are less than desired, broken, or missing, it's off to the market to look for replacement caps that can be easily taken off and put back on quickly. With this it is either a cheap generic, an original, or something from another brand (new or old) that fits and does the job. I always choose the last option.

I for one have an interest in using old vintage lens caps, first because they are made better and look nicer than the newer ones. Not to say that some new caps made specifically for that new lens isn't great either (example, the Olympus 12-40mm lens cap).

My favorite cap design at that I keep going to are old Nikon caps with the side pinch. I try to buy and use these as I find them and they are great.

Anyone with this interest and have nice caps to show?

None of the reviews used a GH2/GH3 with the lens. They're all using Olympus cams with it.

My concern is that the distortion will be AWFUL with a GH2/GH3 because it doesn't have built in correction like the latest Olympus cams do.

Can anybody confirm or prove this? How does the lens fare with the GH2/GH3?

I've just hired a 45mm TSE lens for 48hrs, it cost me about £52 including the return postage. The 48hrs didn't include the delivery and return day. They box up the lens in a plastic tupperware style box and a very soft lens bag. The service seems quite pleasant.

Not used a TSE before, here are my experiments:

Anyone have a clue?

I am going to attempt to make an adapter for it, but as of right now the focal distance is almost 6 inches so I am going to need some sort of reducer lens assembly to get it closer to the sensor.

Does anyone have any ideas as to how I could do this?

I have tried a macro step lens kit, tried taking out the rear assembly out of some old broken lenses to see if they would do the trick and unfortunately with them on it vignettes too much to use.

The closest thing I have found was a 50mm f4 development enlargement lens but still vignettes and obviously reduces that 1.2 to a much higher Fstop.

I would really appreciate some input from anyone who has attempted to make adapters themselves! This would make for the fastest wide angle ever!!

think 1.2 at 8.5mm

TASTY!

I just recently wanted to buy a fisheye lens to filming skateboard videos, but I came across 2 different fisheyes :

• The Rokinon 7.5mm f3.5 for Micro 4/3

Or

• The Rokinon 8mm f2.8 for Sony E-mount (NEX-7, NEX-5, NEX-3...) + Adapter

The thing is I know the Rokinon for M4/3 is going to fit directly on my camera (tried it in a shop), but the Rokinon for Sony is much faster, but maybe a little less wide...

Can you please help me choose ?

Thank you.

Second: if it isn't, i would like to discuss with you about the "bargain" sometimes i read we can do with this lenses. This bargain, is it real? I'm starting to look for some video solutions for me: Nikon d5200 or Bmpcc (it depends how much you want to spend). But it's not an individual problem, cause with mft mount (gh2-gh3-g6-bmpcc) you can use every lens, pratically, while nikon has always its "F" mount, and that's special: you could invest in some lens while you have aps-c sensor, knowing you could use the same lens on full frame.

So, which lens do you suggest? Wide and fast solutions? Thanks to all.

Still thinking hard if i should get it should it become a reality, or invest in Metabones SB to go with my suite of Zeiss. My widest now is 18mm. Shooting on BMCC 2.5k

This movie has been shoot a week-end mid october in Bordeaux, and first week-end of november in the countryside. I'm glad to have now I think the perfect anamorphic set combination for my baby Hypergonar anamorphic lens. I bought few weeks ago a used Qioptiq C-mount lens, usually used in industry. This lens is very sharp, even at it's fastest aperture (f1.6) and this wide aperture is still usable with the anamorphic on it ! Some of the shot of the movie had been taken at f1.6.

It was not possible to screw directly the anamorphic lens on the Qioptiq prime lens because the front barrel is turning when you focusing. So I ordered a special machined flat step up ring to attach the two lens. I've unscrewed the ring on the Qioptiq that is maintening the glass, and replace with the special machined flat ring. Then I screwed on it the original small Berthiot clamp that can align the anamorphic lens. Then I put the baby Berthiot hypergonar in it. The combination suits perfectly ! The weight of this anamorphic combo is quite light. The Hypergonar weight is 57 grams, the clamp maybe 20 grams, the Qioptiq is 210 gram, then the two filters (diopter + variable ND) and step up rings maybe 150 grams. So the total is around only 400 grams ! And finally using the OM-D with it's 5 axis stabilization system with an anamorphic combo is very useful !

Some have suggested in getting:

http://www.bhphotovideo.com/c/product/546271-REG/Pentax_C22525KP_C22525KP_1_C_Mount.html

somthing similar to that.

I sent it back to the shop and got a new copy today. Went out to do some tests and... Well, the difference between the left side and the right side is improved (not 100%), but its still extremely soft towards the corners of the frame on all sides. Not even that far out of the center... At f8 these problems are pretty much gone, and very much usable at f4 - 5.6, but that's not what I paid this money for... The reviews clearly said sharp at F2.0 throughout the frame.

Well, I might be stupid or crazy, so I want to ask your opinion. The front element of the lens is 'rounded' and that's exactly how the 'sharp plane' looks like in my test shots. Like there is a 'circle of sharpness' in the middle of the screen.

Note that I use the Panasonic GH3 with an adapter (have tried 2 adapters btw). The lens has a Nikon mount. This shouldn't affect this problem, right? Take a look af the softness on the right and especially left sides.

All pics are shot at large apertures (f2.0 - f2.2) except for the last one, which was stopped down to f5.6 to correct the problem to show the difference. Did i get a faulty lens twice? Are the reviews false? Does this lens not work with an adapter? Camera's fault? Or is it just 'normal'?

Hope to hear your opinion. Thank you so much.

Lens seems to be early prototype now.

Samyang announces the introduction of series of full frame lenses with Sony E-mount.

Krakow, October 16th 2013 - Samyang informs about the release of a new series of Samyang lenses for Sony E mount.

Within two months Samyang lenses, appreciated by both of professionals and amateur photographers, will be also available with Sony E-mount. High quality optics, that makes Korean products famous across the world, will please not only DSLR cameras owners, but also users of Sony NEX and Alpha family.

Series will be available with the following focal lengths:

• Samyang 14mm f/2.8 ED AS IF UMC
• Samyang 24mm f/1.4 ED AS IF UMC
• Samyang T-S 24mm f/3.5 ED AS UMC
• Samyang 35mm f/1.4 AS UMC
• Samyang 85mm f/1.4 AS IF UMC

All lenses guarantee high quality image with simultaneously high aperture. Use of lenses made of special optical glass along with aspherical elements allow to effectively eliminate optical defects, together with care of the highest performance.

Samyang Sony E-mount series will allow all Sony NEX owners to fully experience high quality optics without additional adapters. Giving the fact, that lenses are prepared for 35mm format, they will perfectly work with not only APS-C cameras, such as Sony NEX 7, but also with the newest Sony Alpha 7R and Sony Alpha 7.

At the moment Samyang provides VDSLR series with Sony NEX mount, which has been designed especially for videomaking purposes:

• Samyang 14mm T3.1 ED AS IF UMC
• Samyang 24mm T1.5 ED AS IF UMC
• Samyang 35mm T1.5 AS IF UMC
• Samyang 85mm T1.5 AS IF UMC

All constructions mentioned above are not only the highest class of optics providing best quality image, but also casing and mechanics built in a view to filmmakers requirements. They can easily be used with popular DSLR cameras having the function of recording, and they are also available for Sony E cameras. This creates a chance to use them with Sony NEX-VG900, NEX-VG30, NEX FS100E or older types without additional adapters.

From the article:

Modern imaging optics are highly complex systems consisting of up to two dozen individual optical elements. This complexity is required in order to compensate for the geometric and chromatic aberrations of a single lens, including geometric distortion, field curvature, wavelength-dependent blur, and color fringing. In this paper, we propose a set of computational photography techniques that remove these artifacts, and thus allow for post-capture correction of images captured through uncompensated, simple optics which are lighter and significantly less expensive. Specifically, we estimate per-channel, spatially-varying point spread functions, and perform non-blind deconvolution with a novel cross-channel term that is designed to specifically eliminate color fringing.

A completely re-built and re-engineered precision optic. The photo below shows a prototype.

Preliminary Specification:

• super sharp anamorphot utilising optics that won Schneider Kreuznach Academy Awards for technical achievement
• 4 K aquisition friendly
• focal range from 0.75 metre to infinity, without dioptres
• large 50mm rear optic port
• 2X aesthetic, stunning blue flares and 2X oval bokeh
• support for Flex-eDrive* focussing accessory
• supports lenses from 40mm (APS-C) for 2.35:1 format
• supports lenses from 30mm (APS-C) for 2.35:1 format via Canon RAW 4:3 crop modes
• lens support for 15mm rod/rail systems included, for quick lens change and assured vertical alignment
• suitable for manual, auto focus and rotating-front-element lenses
• push on lens shade included, easily removeable
• 77mm filter thread included

Flex-eDrive is a planned product which functions as a flexible drive shaft to permit manual or motorised focus via stepper/servo control

Specifications subject to change and improvement

Initially a small batch will be made with follow up demonstration videos.
