Thanks, the 500mm is crazy sharp. Just an outstanding lens.

Not on a Q but....

Good point. I converted a couple of Rokinon Canon EF mount lenses to Sigma SA (using Pentax K mount extension rings) and in that case it was easy as the backs of the mounts were totally flat. There were really only 3 contact points at each of the screw holes.

I guess it totally depends upon if the back of the Pentax mount in the adapter is flat or not.

If anyone has one of these used please let me know. I am looking for the actual Pentax model with the shutter in it.

What's the best wifi SD card for use with the Q7?

I had an Eye-Fi card awhile back that ended up getting discontinued before the company went bankrupt. It never worked all that well IMO. I also have the W4 Toshiba card and find that that one actually works a little better. You don't need the on/off function with the Toshiba as it can be set to turn off after x amount of time after the camera turns on. That saves battery power. You can also browse the pictures a little easier with the Toshiba card. Most annoying thing about it is I haven't found a way to select multiple files for download when browsing with a computer. Neither are as nice as a camera with built in Wifi but are better than nothing if you want that functionality. I use the W4 in an original x100.

Thanks for the information on the adapters. I was thinking the K mount side of the adapter looks like it would just unscrew so it should be pretty easy to drill a Nikon mount flange to screw in its place. To get fancy one could add a 1.04mm spacer behind the Nikon flange to maintain proper flange distance. That would be helpful on the 500mm as the infinity stop is right on the mark.

Now if I could just find that adapter used....

Thanks,

Shanw

The 500 F4P is an amazing lens, every time I use it it impresses me. I didn't try the Sony without the TC301 but without it the crop would have been pretty small. The resulting crop with the TC301 in place is around 10MP. Next clear night I will try it. With it on the Q I think I was getting motion blur, the electronic shutter probably wasn't helping there. Wonder if the Pentax K to Q adapter could be adapted to Nikon mount to get an actual shutter?

The TC301 is the recommended teleconverter for the 500 f4p.

Pentax Q-S1 with Nikon 500mm F4P. Uncropped. The Q had more detail than shots I also took with a Sony A7RII with the same lens plus a 2x Nikon TC-301 teleconverter.

Nice, glad others are enjoying the Fuji too. It is a great little lens for not much money. As far as a lens cover I have just used a small velvet cinch bag over the lens so far. At some point I will see about trying to 3D print a lens cover for it.

Yup, that is a Q-S1 that the lens is mounted on. If anyone else want to try one check ebay for the Axis 212 security camera. They apparently have that Fujinon in them and the cameras are available cheap on ebay.

LCDs are polarized and if they are opposite the polarization of your sunglasses you will completely black out the screen. I think the screen is OK with my polarized sunglasses when in landscape but if I rotate to portrait orientation I can't see the screen at all.

An OLED display would not have this issue.

Fujinon CF2.7HA-L1 2.7mm f1.8 Fisheye.


The lens as delivered is a M7 mount (with a flange distance of under 2mm and a screw size larger than C mount) but the M7 mount will unscrew and under it is a standard C mount thread with the proper flange focal length. I think this lens is sold by Fujinon in a few different versions and mounts. I believe they are all fixed focus but some have aperture controls and some do not. This version is wide open all the time.






First shots playing around...









The FOV is *very* wide and many shots had feet in them. The uneven vignetting is a little odd (mostly left corners) but not an issue IMO. Seems plenty sharp (all are wide open as there is no aperture) and I have tweaked that slightly with a spacer.

My original Q with the 01 prime had a problem with its SD card slot so I haven't used it in years. Just picked up a red/gunmetal Q-S1 with the 02 zoom and was walking around with it today.













The 02 is a fun little lens. I totally ignored it with my original Q, that was a mistake. Just ordered an 06 to go with it.

what is highlight alert on the mx-1 used for?

Areas that are overexposures will be shown in red, areas that are underexposures will be shown in blue. It is handy for times when the lighting is difficult and can be useful to helping set exposure compensation quicker.

MX-1 and latest big sensor compact cameras

"Is the MX-1 outdated and you should upgrade to a Sony RX100/3 or Panasonic LX100?"

MX-1 takes great shots. As every one said the lens is really good and I have gotten some very great shots with it. Having said that I bought a RX100/3. A big part of that was due to size. RX100 fits comfortably in a shirt pocket, the MX-1 can't do that. I prefer the simpler interface of the Pentax to the Sony though I have found the Sony to not be as bad as most say.

As far as shooting hand held in low light my money is on the Sony. Lens speed is very similar between the two and the Sony handles high ISO better than the MX-1. Additionally I find that using the EVF is a more stable shooting position than using a rear LCD.

My problem is what to do with my MX-1. I should sell it but I am strongly considering converting it to an IR camera.

MX-1 - Hyperfocal Focusing

Yes, the MX-1 has an additional feature too. It will automatically go to PF if you just mash down the shutter release without stopping halfway for focus first. With that you don't really even need to use the PF setting. Just leave it in normal AF mode and if you have a situation that requires PF just mash the shutter release down.

Last weekend I went to an airshow and decided to shoot it lightweight this year. Normally, I would go with a D700 a 500mm F4P lens that I would shoot handheld. I was going to shoot with the Q and a Nikon 80-200 F2.8D but ended up going for even less weight by using a plastic Nikon 80-200 F/4-5.6 lens. Using a well dialed in red dot sight I just put the lens on infinity and turned off the rear LCD to just use the sight.

And just to keep things more interesting I was on a boat....

Here is the airfield shot using an iPhone 4s to give a sense of magnification.


Same thing but from the Q with the Nikon at 200mm. This is the full image, not a crop.











With the prop planes the non-global electronic shutter ended up resulting is some odd distortions. I couldn't shoot with slower shutter speeds (to blur the props completely) as I would get overall blurring due to the motions of the boat and the effective 1000mm FOV.





Most shot around RAW ISO 800 and F5.6 or F8 on the Nikon.

Of course the quality wasn't to the same level as if I had used my big rig but this fit into a tiny Domke F5XB bag!

" but nothing as wide as a 4, and certainly not for C Mount"

They are out there. I have a 2.5mm C mount fisheye for example. Pentax/Cosmicar has a 4.8mm C mount lens that is a nice focal length on the Q. I have a 3.6mm (I think) but it optically isn't as good as the 4.8.

I have the same case,works very well with the Pentax. The shoulder strap is very slippery though, I swapped it out for a Domke gripper strap. I also added a small Optech neoprene battery holder to the strap for a spare battery.

If you read the rules in order it starts off with the 1" sensor size limit (along with no ILCs) but then has the line...

Cameras permitted (cameras listed as acceptable here supersede rules above):
...
Fixed-lens 35mm and smaller-format film and digital rangefinder and viewfinder cameras.

That should mean an APS-C camera with a fixed lens (like the GR, X100 or Sigma DPs) is allowed.

"I can't find it on woot?
Is it just a daily deal thing on there?"

Woot has their daily deals as well as some that last a few days. Right now the MX-1 (and Q10 and K500) are on a deal that ends Feb. 6th.

MX-1 is getting so cheap I'd love to get a second one and modify it for IR.

"to get into macro mode like with similar cameras - the MX-1 does it automatically."

Up to a point. It has two macro modes. In regular autofocus mode it will go into the second of the two macro modes automatically. However, for the nearest macro mode 1cm (which fixes the zoom position) you do need to hit a button to change the focus mode. Another nice focusing feature is the mash the shutter PF feature, though the AF itself is very fast on the MX1.

Available on Woot right now for $199. I bought mine from them a couple of months ago (@249). Great little camera.
