Maybe. We are seeing a large number of high-resolution camcorders that have fixed lenses. The ability to use different lenses is not available.  Or are they? By their nature, zoom lenses have additional optical elements that allow for the zoom function but sacrifice bokeh and are generally not too fast.  Reality, doc's BTS's don't generally need narrow D.O.F..  Cinema generally does.

Funny thing is, manufacturers are putting out 4K cameras with fixed lenses and all have included 24-frame capability, generally reserved for cinematography creating that good ol' film look.

Fixed zoom lens and 24 frame? Rarely the tracks

shall meet.

Creating enhanced depth of field (D.O.F.) is

with both zoom and prime-type lenses (those with

fixed focal length) though most would agree prime's

are the way to go. 

Since a fixed-lens camera doesn't allow other

specialty lenses to be used (such as a prime lens),

the filmmaker may have a problem in creating the cine look-and-feel deemed necessary to the needs of the production.


HSR was, for a moment in recent past history, one of America's largest
Letus35 D.O.F. adapter rental firms. We carried all three different models (that did roughly the same thing) and many different lens mounts from Nikon, Canon EF and FD, Zeiss Conterex (CY), M42 and even PL.

After we set them up they looked quite nice. Many went out on a given day or weekend on earlier cameras such as the Panasonic AG-DVX100A, Sony PMW-EX1,and others. The results for their day was shockingly effective. Very sixteen millimeter -ee.

The zenith of the adapters use and broad acceptance peaked about five years ago. Their popularity waned in the face of so many cameras having removable lenses, from DSLR's to traditional camcorders. Cameras no longer shipped with a lens at all.  What does one do if you own or have access to one of the great fixed lens cameras currently on the market, and you need to shoot a more film-feel project?


A DOF adapter focuses an image onto a translucent screen or piece of ground glass (similar to how one would look at a focused image through a system camera's EVF) located between an external lens and the camera's fixed position lens.

The camera is able to frame this intermediate screen by focusing in a macro mode. The principle is similar to pointing a video camera at a movie screen. The lens attached to the adapter now takes the job of the camcorder's focusing and aperture mechanisms.

The camcorder's only responsibility at this point is to record what is being projected onto the focusing screen referred to as “back focus”. Simply zoom into your “new” frame and focus.

Inserting the adapter in the optical pathway will reduce light transmission by about 1/2 of a stop. Generally, this will not pose a problem for the camera.


If you already own a few prime lenses from your SLR days, here is your justification for holding on to them, even if you didn't know it at the time. Whether you own Canon EF, FD, Zeiss CY, Nikon,M42 or even PL, various front-of-adapter mounts allow you use them in a D.O.F. adapter configuration.  Some old lenses have a certain look to them which can be very desirable. 


We've sold off over a dozen systems over time but decided to keep one system for the historical record. It works great but gets very little work. Until recently.

Now I'm getting more bookings and seeing several better (read: newer) cameras with fixed lenses that, in concert with the adapter, produce very convincing imagery. As previously mentioned, everybody's getting in the game. As of mid-August 2015 the list continues to grow in fixed 4K:

Canon XC-10, JVC GY-HM170, Panasonic HC-X1000 and AG-DVX200 (shipping soon), Sony PXW-Z100 and FDR-AX1.

Great. More new model numbers to remember.  Getting double-duty from a new camera makes good sense. Applications from a more ENG-style run-and-gun where auto-focus and a powered zoom lens is required to Cine-style where most elements are in hand. 

Bring in your camera for a test fitting. No charge.

The Fastest Memory Cards Money Can Buy

By Chris Gold

Nobody has ever complained about a memory card being too fast and, increasingly, electronics manufacturers expect you to have high-speed memory cards to enable certain features. Smartphones, tablets, and even laptops often rely on memory cards for external storage these days. And, with consumers demanding both higher resolution and less compressed video from cameras, manufacturers have responded by supplying more and more capable memory cards. Today, cameras are recording 4K video to microSD cards and RAW HD video to SD cards. Luckily, memory cards have kept up with the rising demand, and the fastest cards around rival SSD drives, though finding out which ones are truly fast can be a challenge.

How to Determine Whether a Card is Fast, and the Dreaded “Up To”

When memory cards list their                                                                           read and write speeds, they often use terms like “up to” or                                                                                     “maximum” when referring to the spec. A maximum read speed                                                                           or speed “up to” a certain amount is the maximum burst speed                                                                             of a card. It might be able to sustain that speed for a few                                                                               seconds, which is great for quickly saving a picture, but                                                                               don’t actually expect to see read and write speeds like that for                                                                             sustained transfers, like shooting video. Plus, some                                                                                                  manufacturers are a bit more liberal with the speeds they                                                                               quote than others. Sustained transfer speeds can vary greatly from card to card, so to determine a memory card's overall speed by just looking at the card's advertised maximum speed isn’t always the best method.

Luckily, memory cards have a number of metrics to help you sort out which ones are fast all around, though, to the uninitiated they can be a bit overwhelming and look like random numbers. In this article we will not only tell you what the fastest cards are, but also help you understand why.

SD and microSD Cards: SD vs. SDHC vs. SDXC

One of the more obvious metrics we use when comparing SD cards has to do with whether they are SD, SDHC, or SDXC cards. While all these cards look same, the file format they use is different, which determines the maximum capacity of the card. Plain SD cards have a maximum capacity of 2GB, while SDHC cards max out at 32GB; SDXC cards can support up to 2TB—though we aren’t there yet. This metric does not affect speed at all; an SDHC card can be just as fast as a SDXC card, and oftentimes they are.

UHS (Ultra High Speed) Card Classifications

Some SD cards have UHS (Ultra High Speed) Classifications. A UHS (Ultra High Speed) Classification determines the maximum speed at which a memory card can read. This doesn’t affect the speed of the memory in the card, but manufacturers will rarely make a UHS-I card that is unable to read or write faster than a non-UHS card can. Non-UHS SD cards max out at 25 MB/s, but UHS cards can be much faster. Currently, there are two types of UHS classifications: UHS-I Cards, which have a maximum theoretical speed of 104 MB/s, and UHS-II Cards that allow for a maximum transfer speed of 312 MB/s. UHS-II cards also have a second row of electrical contacts to aid in the speed boost. If your memory card reader or camera does not have the second row of contacts, the speed will be more in line with UHS-I cards. A card’s UHS classification is a good way to help gauge its burst speeds.

Speed Class Ratings

Since card manufacturers almost always only give you burst read and write speeds instead of sustained speeds, it can be difficult to pick out a card for video. Many new 4K-capable cameras write at very high bitrates, and if you plan on recording video for longer than a few seconds, the burst speed doesn’t help much. Also, there can be huge variations between the maximum burst read speeds and the minimum sustained write speeds of different cards. It’s not a simple ratio. To determine the minimum write speed of a card, you need to look at its speed-class rating. A speed-class rating means that the card has been verified to never write slower than a card in its classification. Some cards may write a lot faster, especially since the fastest speed class is currently just 30 MB/s, but you can be comfortable knowing that any card with a speed-class rating will never write slower than that speed. Some popular speed class ratings used on SD cards today are:

U3- Minimum 30 MB/s Read
U1- Minimum 10 MB/s Read
Class 10- Minimum 10 MB/s Read
Class 6- Minimum 6 MB/s Read
Class 4- Minimum 4 MB/s Read

The Fastest SD Cards

Now that we’ve decoded all the technical jargon, it should be clear that if you want the fastest SD cards you can get, look for UHS-II, class U3 cards. And luckily, we carry a number of UHS-II U3 cards from a few manufacturers. SanDisk Extreme PRO UHS-II cards are available in 64GB, 32GB, and 16GB capacities, and offer read speeds up to 280 MB/s and write speeds up to 250 MB/s, which should satisfy the most bandwidth-hungry cameras. Delkin also offers a 32GB card with the same 280 MB/s maximum read and 250 MB/s maximum write speeds. For those willing to trade a little speed for more capacity, Lexar’s Professional UHS-II cards are available in 256GB and 128GB capacities and offer a slightly slower maximum read speed of 150 MB/s.

If you do not have a UHS-II capable camera or computer but still need a fast card, take a look at the SanDisk Extreme Pro UHS-I U3 memory card line, available in 128GB, 256GB, and 512GB capacities. These cards offer read speeds up to 95 MB/s and write speeds up to 90 MB/s, very close to the maximum possible speed of UHS-I.

The Fastest microSD Cards

MicroSD cards are essentially miniaturized SD cards, and share the same UHS and class properties as their full-size brethren; however, as of now there are no UHS-II type microSD cards, so the fastest cards are UHS-I class U3 cards.

Delkin Devices offers UHS-1 U3 rated microSD cards in 32GB and 64GB Capacities. These cards offer up to 99 MB/s read speeds and 50 MB/s write speeds. SanDisks’s fastest microSD cards are the Extreme Plus line, which offer maximum read speeds of 80 MB/s and maximum write speeds of 50 MB/s. They are available in 16GB, 32GB, and 64GB capacities. If you need more than 64GB of space along with high speeds, the 128GB Lexar High-Performace UHS-I microSDXC Card offers read speeds up to 95 MB/s.

Compact Flash Cards

CompactFlash cards used to be the faster and more professional big brother of SD cards; however, several years ago the CompactFlash Association announced there would be no more updates to the format, leaving card performance with a glass ceiling. Today, CompactFlash cards have hit their performance ceiling, and are slower than the fastest SD cards, though they are still quite fast. The UDMA 7 interface has a maximum possible transfer speed of 167 MB/s. Even if a card manufacturer put faster flash memory in a UDMA 7 card, it wouldn’t matter—it would be like plugging an SSD drive into a USB 2 port on your computer (well, not quite that bad, but you get the point). The bright side is that the sustained transfer speeds of CompactFlash cards will most likely be a lot closer to the maximum speed but, since manufacturers don’t share that information, it is difficult to verify.

CompactFlash Card Speed Class Ratings

Many CompactFlash cards have speed ratings like 800x, 1066x, 400x, etc. This speed-rating system is quite old and is based on the data-transfer rate of audio CD files, a paltry 150 KB/s. Needless to say, this doesn’t have much bearing on anything you will probably be doing with your cards, so while you could figure out how fast an 800x card is in KB/s  by multiplying 150 by 800 and convert KB/s to MB/s by dividing by 1,000 (the answer is 120 MB/s) you could also just go by a card’s stated 120 MB/s speed.

The Fastest CompactFlash Cards

Because the maximum speed of CompactFlash cards has been capped at 167 MB/s, for a while almost all card manufacturers offered cards capable of peak read and write performance at that speed. The fastest cards will be UDMA 7 and are advertised as having maximum read speeds between 160-165 MB/s. Lexar’s fastest line of CompactFlash cards is the Lexar Professional series, available in capacities from 16GB and 256GB. Lexar rates these cards at 160 MB/s maximum write speed and 155 MB/s maximum read speed, as well as a minimum write speed of 65 MB/s. SanDisk’s Extreme Pro line of cards also offers similar performance of up to 160 MB/s read and 150 MB/s write speeds. The Transcend Ultimate,Toshiba Exceria, and Delkin Devices Cinema CompactFlash card lines also offer similar maximum read speeds, though their write speeds are a bit slower than the Lexar and SanDisk cards. All of these cards are as fast as CompactFlash cards are going to get; if you want something faster, you will need a different type of memory card.

New Memory-Card Types

XQD Cards

XQD Cards are the reason CompactFlash cards aren’t getting a speed update, as they are the CompactFlash Association’s official replacement for CompactFlash cards. XQD cards offer far higher maximum transfer speeds than CompactFlash, are much smaller, and have a more rugged build than SD cards. There are currently two versions of XQD cards: Version 1.0, which allows for maximum transfer rates of 500 MB/s, and Version 2.0, which allows for speeds up to 1,000 MB/s. While still limited in use, both versions offer faster possible transfer rates than the fastest CF or SD cards available. 

The Fastest XQD Cards

Currently Sony is (still) the only XQD memory card manufacturer, and its newer XQD Version 2.0 cards, available in 32GB, 64GB, and 128GBcapacities, are the fastest ones around. All three cards offer extremely fast read speeds of up to 400 MB/s and write speeds of up to 350 MB/s. When it comes to speed, these cards give computer SSD drives a run for their money.

CFast 2.0 Cards                                                     

Despite the fact that CFast cards look almost identical to CompactFlash cards they represent a completely different standard, and will not work in CompactFlash card slots or devices. They are not backed by the CompactFlash association, but are beginning to pick up some steam due to the slow adoption of XQD cards. CFast Cards use SATA connectors to interface with computers and cameras, and the new CFast 2.0 cards use SATA III, meaning they allow for the same maximum transfer rate of 6 Gb/s (750 MB/s) as SATA III drives. While the interface isn’t quite as fast as XQD 2.0, there still aren’t any cards in either format that come close to the maximum possible speed so, at this point, it isn’t really an issue.

The Fastest CFast 2.0 Cards

Currently, both Lexar and Sandisk offer CFast 2.0 cards. The Lexar Professional CFast2.0 cards are advertised as having up to 510 MB/s read speeds and come in 256GB, 128GB, 64GB, and 32GB capacities. B&H also carries SanDisk Extreme PRO CFast 2.0 cards that can reach read speeds up to 515 MB/s, which would make them the top contender for the fastest memory cards mentioned in this article.

So if it’s performance you need, you have to pick sides, CFast 2.0, XQD, or UHS-II-It’s all up to you—well, really it’s up to device manufacturers, but at least now you know how to find the fastest cards available.
