In an effor to shave off those ever so precious last few grams of equpiment weight (just do not look at the 20+ pounds on my "spare tire"), here is my latest creation:

http://www.dlsphoto.net/Monopod_Pano_Head/top.jpg http://www.dlsphoto.net/Monopod_Pano_Head/bottom.jpg

Note the shaved monopod head. 5 degree tilt. A hand held Nadir patch shot is more than enough to cover what little bit of this pano head is left in the picture.

Finally have had time to play with my NEX-5/Samyang 7.5 lens combo. Here is the 2lb 1oz solution (total weight including the monopod) I now have for cycling and hiking.

Only the clamp from my R1 pano head remains.

Hi Dennis,

Thx for sharing. Nice looking.
Wow, you machine the ring from solid aluminum! That is more expensive than our lens ring.
BTW, our lens ring for Samyang 7.5mm is shipping next week.

Hi Dennis,

Nice garage! Would like to have one. So to see you machined the adpater ring as well. Could you please tell us a bit ore about alterations on the lens and the adapter?

@Nick that's quick. well done.

Regards,
Heinz

Nick,

Actually, I machined it from a piece of scrap L shaped aluminum extrusion. Materials cost me about $3.00 and I have enough for 3 more adapters. Since I am more concerned with function over marketability, I have the luxury of making something work "one off". There is no way this design would sell on the market. It is more of a “proof of concept”. Since you are already tooled up for production, machining a new plastic insert makes sense and is cheaper for you.

Heinz,

The MFT/NEX adapter does not allow the lens to focus at infinity. You have to take the back mounting flange off the lens. There are 3 very small screws. Once you remove the screws, you simply lift the mount off. Remove whatever spacers you find (this differs from lens to lens), then bolt the mounting flange back on.

I took this one step further by drilling/counter boring 3 holes in the MFT/NEX adapter. (Thanks Smooth for that one). I used the three bolts from the mounting flange to bolt the adapter back onto the lens. I also removed the spring steel piece and turned down the outside diameter of the adapter. Now the lens looks like it has a small brass ring in the back.

The body of the lens is plastic, so don't be too aggressive when putting the screws back in place. It would be a shame to strip the threads.

The front lens hood also needs to be shaved. The ring on the front that has the lens name and such stenciled on it can be GENTLY pried off. You will find another set of 3 very small and easy to lose screws. Once these screws are removed, you can lift the lens hood off. This makes shaving the lens hood much less dangerous. If you completely remove the petals from the hood, you will not have any place for the lens cap to grab onto.

Hi Dennis,

Thx a lot for explanation. Did you have to machine the lens flange itself as Smooth mentioned when I remember well to get "free space" before focussing to infinity?

I am as lucky as you have been. Foto-tip can not deliver cause they have run out of black 7.5 samyang lenses. Though waiting for weeks now, it will probably take another one. Though my money was booked, I did not get a mail for delay. I had to send them two mails to get response.

So everybody who likes to order the lens now in EU or even in US, Andrew Badders has them in stock since a while too. USPS shipping to US or the other way around US to EU always takes weeks and offers very bad track and trace. To Us it still says "to be set ready to deliver at sender" even the day it arrives in US.

@Andrew, do you have the adapter for Sony NEX-5 as well?

Regards,
Heinz

Heinz,

I just machined .012" off of the inside of the mounting flange (the thickness of 1 brass shim, just in case I messed up). F11 now looks good across the entire image. F8 is still soft along the edges. Smooth was right about machining off material. He was not right in how much. If I were to take off the thickness of the adapter as well as the shims, that would have been .065" Focus at infinity would not even be close. I think I still need to find longer screws.

Tracking from EU was horrible. The status never changed even after I accepted delivery. It took 12 days or so to get here. So far, it seems to be well worth the wait as initial tests continue to look good.

For that hand held Nadir shot:

This is the bottom of the camera, the side that faces you when you hold the camera out for the Nadir patch shot.

UPDATE: SOLD OUT! We are waiting for stock as well. Pre-order or subscribe to the RSS stock feed on my site and get in quick as these little gems are selling like hot cakes!

Err.... Which adaptor would that be?

I find that leaving the camera on the monopod and just holding the monopod horizontally over the nadir works just fine and I can back off far enough to get a nadir that has a "friendly" shadow.....

Trying to do that in a crowd reminds me of a 3 Stooges movie. "Watch it! You'll put someones eye out with that thing!"

Besides, everyone knows that photography is all about having all those toys. Forget about talent. More hardware will always make better pictures!

Bill,

DennisS decided to machine his own lens ring cause he wants to use it for his next trip. I tested the panasonic lens ring with Karel for Samyang 7.5 and we found out that there has to be different insert. DennisS was informed about this.:th_wink:

Nice that it will be delivered next week. Thx Nick.

Be aware that there seem to be a lot of people waiting for this lens ring. Also on panoguide. I ordered at Foto-tip, the first one to deliver before Andrew had them in stock.

I still am waiting, cause it is sold out in Poland.. Takes another week or two.

Andrew told us he is sold out too cause they sell like "hot cakes". So the lens ring should sell like a hot cake too:rockon:

Cheers,
Heinz

I continue to spend a lot of time solving several issues associated with getting the Samyang lens to work with the NEX camera.

One major problem is a type of lens flare that I have never seen before.

http://www.dlsphoto.net/Samyang75PanoHead/Flare.jpg

Usually I can use intelligent fill to remove lens flare. This type of flare had got me stumped. I cannot use a different f stop since image quality will suffer.

I tried tilting the camera up 45 degrees to take another shot at the same view. The resulting image stitches in quite nicely and, with proper masking, deals with the flare.

Tilting up 45 degrees when using the R1 is a real pain and rather time consuming. Remember most of my stuff is outdoors in the bright sun shine. The sun sits still for nobody and will not wait for you to finish shooting your panorama. You gotta get your pano shot quickly so the shadows line up easier.

This very small pano head allows you to very quickly take the shot into the sun, tilt up 45 degrees, take a "patch" shot, and then continue on.

http://www.dlsphoto.net/Samyang75PanoHead/MiniNN3A.jpg

Tilted up 45 degrees:

http://www.dlsphoto.net/Samyang75PanoHead/MiniNN3B.jpg

There is also a setting that allows tilting up 90 degrees.

You can still see bits from the R1.

I designed this so I can keep my right hand on the camera while photographing the entire sequence. My left hand takes care of steading the monopod as well as releasing the pin for upward rotation.

When deciding what and how much equipment to take along, one must look at the entire process, from picking the spot to publishing on the web. Is it better to use the D300/Sigma 8mm or the NEX/Samyang 7.5? At this point I am satisfied with the images out of the NEX. Is it worth taking this small pano head over the R1? For the NEX a resounding YES. This rig is still very much smaller and lighter than the D300 rig. The finished panoramas are very similar in appearance. I am almost ready to commit to taking this camera on my trip next week. I have not published any panoramas yet because I do not want to throw something together just for the sake of publishing.

I saw that kind of flare all the time from my LX3+wide angle adapter. One way to deal is to take one dead on the sun and then one to the left and one to the right about 20 degrees. With mask and blending they go away. No tilting necessary -- with my stuff -- that I sold.

You don't have to stick to a rigorous 4 around on 90 degrees. Shoot freestyle. More pictures to combat flare. Shoot 5 or 7 or 8 around as you need to. PTGui fixes everything.

For those of you keeping score, here is the latest.

I had to face .027" off of the back side of the lens mounting flange and the locating lip. Putting the shims back in brought the distance down to .012". This allows infinity focus and corrects issues with stitching. The optics are too far away from the sensor using a stock lens and adapter. Smooth has confirmed that material needs to be removed.

I finally went out and purchased a rotary table. No more champhers. I can do real circular milling. Sure wish I had access to a CNC mill.

Here is what my pano head looks like so far:

http://www.dlsphoto.net/Samyang75PanoHead/Samyang75PanoHeadC.jpg

Total weight as pictured is 146 grams.

That is an electronic level hanging off of the left hand side. It helps me level out the camera for taking the hand held Nadir shot. I have not made up my mind yet if the level saves or costs time.

Here is how I hold the camera for the Nadir patch shot. My ring finger fires the camera.

http://www.dlsphoto.net/Samyang75PanoHead/Samyang75PanoHeadD.jpg

This is one small package!

I am having success controlling lens flare by taking 5 around without the need for a zenith shot. Looks like the mini NN3 will not be put into service.

As soon as I finish figuring out the Nodal point and focus/f stop settings, sample panoramas will follow.
