Related Questions and Answers

Q: 1. What is the focal length of the lens?

A: Hi--the equivalent focal length of this camera is 31mm.

Q: 2. Hello guys :)Will this IDX P-V2 V-mount camera plate fit the Ursa Mini please ?Thanking you

A: Sorry, I don't know what is Ursa Mini. I just use of power supply for other party.

Q: 3. Can DHI-VTO2311R-WP camera auto focus?

A: The Dahua Technology DHI-VTO2311R-WP 2MP Wi-Fi Villa Door Station does not have autofocus. However, the camera's fixed focus distance will keep the focus of targets within its distance range. Which is about 6-10 feet (ca. 3 meters).

Q: 4. Does this plate come with the appropriate molex adapter for the Blackmagic URSA?

A: NO adapter

Q: 5. Does this come with the 3 sets of ilford photo film?

A: No it does not. I just bought this kit and it comes with the camera and the paper exposure calculator. You will need to buy a 4x5 film holder and 4x5 film (or 4x5 direct positive paper) to use this camera. (The older version of this kit did include film but that version is no longer available.)

Q: 6. Could a groundglass be made to fit in the film holder slot?

A: i'm sure you could but I don't know that it would be all that helpful.

Q: 7. How is the camera guided for direction change?

A: Slowly troll (less than 2 mph) or drift along the structure you intend to view. The camera will face in the boats direction of travel. If youre facing and moving forward, so will the camera; it will show you the underwater terrain in front of you. The stabilizer fin always keeps the camera tracking straight, so long as youre moving. Here is link to the manual as well: http://bit.ly/1mqTIIP

Q: 8. Is this considered a superwide? Does exposure compensation need to be added to expose the long ends of the film/paper?

A: The HARMAN technology TiTAN 4 x 5" Pinhole Camera has a 72mm focal length with a 97° angle of view, which would be roughly equivalent to a 20mm lens used on a full-frame 35mm camera. This would be right near the beginning of the focal lengths considered as a super-wide angle lens.

Q: 9. what is the differencec between this camera and the new one that is available in january 2021? (https://www.bhphotovideo.com/c/product/1612507-REG/ilford_2005152_sprite_35_ii_reusable_camera.html/?ap=y&ap=y&smp=y&smp=y&lsft=BI%3A514&gclid=Cj0KCQiA_qD_BRDiARIsANjZ2LAk3OjNSePKnP93FhGVb3p6TTuBIJXnIQOwU-dLguLkbV4auEFMp3QaAgJ1EALw_wcB)

A: There aren't any significant difference between them, but the Sprite II has an f/9 aperture, while the Harman has an f/10 aperture.

Q: 10. Can you do double exposure?

A: A double exposure would be possible if winding the film rewind dial back. However, it's possible that the frame would be misaligned. Your results may vary.

This kit is simply spectacular. I own some less expensive a/c powered strobes, but I've never ventured into wireless triggers or portable battery powered units. This setup is a dream, and the ability to use TTL and high speed sync is awesome! So far, I use only one strobe with a fast-setup umbrella style softbox for fill and catch lights in eyes. The trigger allows for complex multi-light configurations. TTL and high speed sync have performed beautifully. Hardware quality seems high and durable. Battery life is excellent. For my shoots, using it only as fill, I've never come anywhere close to depleting the battery. The carrying case is also excellent. My only mistake was not understanding that the Bowens adapter ring came with it. I did not figure that out until I order one separately. While I expect to use the Bowens adapter exclusively, it's worth noting that the adapter must be screwed onto the strobe, so it's not something you'll want to swap with the original ring on a regular basis.

This is great for studio shooting. It has some weight to it so be sure to secure it.

I was so used to camera strobes and was reluctant to get this setup, but it turns out that now I'm relying on these much more! Worth the money. I got three.
