Is the sony a7m4 with a half-frame lens okay?
Based on the reference materials, the SonyA7M4 with a half-frame lens was fine. For example, the 18 - 50 camera lens of SIGMA-A was shot in 4K 60P on the Sony-A-7M4.(With 1.5X crop, shooting 4K60P with a full-frame lens would start at 36mm, and the wide-angle would be missing), using a half-frame lens like the 18 - 50 to shoot 4K60P could make up for the problem of the wide-angle. Moreover, there were also people who ridiculed the A7M4 for being good with a Sima 18 - 50 or a Tenglong 17 - 70 (both of which were APS-C frame lenses). These half-frame lenses were a good choice for the A7M4 to shoot 4K60P. Read more exciting novels for free
Half-frame with full-frame lens, okay?
It was feasible to install a full-frame lens on a half-frame body, but there were some problems. From the perspective of angle, due to the small size of the sensor on the half-frame body, the actual shooting angle would be narrower, about 1.5 times or 1.6 times, which had a significant impact on wide-angle shooting. For example, the 50mm full-frame lens on the APS-C camera was equivalent to the 75mm or 80mm lens, which would weaken the wide-angle effect, which was not conducive to large-scale scenery and architectural shooting. In terms of depth of field effect, although the focal length of the lens was longer due to the equivalent focal length, it would not obtain an additional shallow depth of field effect. It might be difficult to achieve soft background blurring in portrait photography. For high sensitivity performance, this mainly depended on the camera's sensor rather than the lens, so a full-frame lens would not improve the high Iso performance of a half-frame camera. The full-frame lens was designed for a full-frame body. When used in a half-frame camera, the edge of the lens would not be used, resulting in the potential of the lens not being fully utilized, and the performance of the lens would be reduced. In terms of image quality, it mainly affected the image quality at the edge of the lens (the center image quality was usually not affected, especially after the aperture was reduced. This effect was not significant on high-quality lenses), and the number of final image resolution would be reduced after APS-C mode was turned on. Full-frame lenses were usually larger, heavier, and more expensive than half-frame lenses. Mounted on a half-frame body would offset the advantages of a half-frame camera being light and portable, and it would also put pressure on people with limited budget. In addition, the autofocus performance of the full-frame lens was worse on the half-frame body. Different brands and models of lenses and bodies might have problems such as slow focusing speed and reduced accuracy, which would affect the shooting efficiency. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The lens combination of the sony half-frame camera is recommended
Here are some recommended lens combinations for the Sony half-frame camera: 1. ** Shooting and video, a combination with a relatively generous budget ** - "SonyE16 - 55mmF2.8G: This is a half-frame big three-yuan lens. It's the best in this focal length. If you can only choose one lens, you can consider it first. - SonyE70 - 350mmF4.5 - 6.3G OSS: The best choice for medium telephoto in half-frame. - [SonyEPZ10 - 20mmF4G: A new lens with excellent image quality and focusing performance. Although the aperture is F4, the ultra-wide-angle blurring is not necessary. You can also choose the Tenglong 11 - 202.8 for photography.] - SonyE15mmF1.4G: suitable for selfie vlogs. It is very useful when you need a large aperture blur and a short shooting distance. You can choose the SIGMA161.4. - SIMA56 1.4: A must-have for portrait photography. If you don't choose this lens, the SonyE50 1.8 OSS can be used as a replacement. - SIMA30 1.4: A great tool for indoor portraits and street photography, but the focal length is similar to the recommended Big Three Yuan. You need to consider whether to choose it based on budget and practicality. 2. ** Entrance-level combination (Considering cost-performance ratio and lens usage)** - SonyT * E16 - 70mm F4ZAOSS: Zeiss Sony-half frame "small three yuan", good picture quality, focus, and lightness. However, the half-frame blurring itself was weak, and the F4 aperture might not be ideal when the focal length blurring was more important. You could also consider the Tenglong 17 - 70mm F/2.8 Di III -AVP RXD. - SIGMAR DC56mm F1.4GN| <strong></strong> - Tamron 70 - 300mm F4.5 - 6.3 Di III RXD(A047): Covers a longer focal length. It can cover 24 - 450mm focal length with a 16 - 70mm lens. It is suitable for traveling. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sony full-frame micro-single installation half-frame lens
It was feasible to install a half-frame lens in a full-frame micro camera. The following situations would occur: 1. ** Picture effects ** - If the APS-C frame mode was not turned on, there would be black circles in the four corners of the camera, and the dark corners would be more serious. For example, this was the case when the camera lens of the Sima 23 1.4 was not cropped on the SonyA7R3. Although shrinking the aperture (such as the SIGMA231.4 under F16 aperture) could significantly reduce the dark corners, the black circles still existed. - If APS-C frame mode was turned on, the dark corners and black circles would disappear. However, after this mode was turned on, the resolution would be reduced. For example, the A7R3 had 17.8 million resolution when it was turned on. Generally speaking, the full-frame body with APS-C trimming could be roughly calculated by dividing the original resolution by 2.25 to 2.4. - In terms of equivalent focal length, after turning on the APS-C frame mode, the half-frame lens would have an equivalent focal length change. For example, when the SIGMA231.4 lens was turned on, it was equivalent to 35mm. The blurring effect under this equivalent focal length was similar to that of the full-frame F2. 2. ** In terms of application scenarios ** - ** Video shooting **: Currently, many cameras have a 1.5X crop when shooting 4K 60P videos (which happens to be the APS-C format), such as the SonyA7M4, A7C2, Nikon Z62, ZF, Pantheon S5, S52, S1H, etc. Some cameras, such as the 1.5X cropped 4K 30P of the SonyA7R5, were over-selected (the un-cropped 4K 30P was not over-selected), and the 1.5X cropped 4K 60P of the Canon EosR5 was also over-selected. In these situations, it was more appropriate to use a half-frame lens to shoot the video directly. For example, it was very common to use a Sima 18 - 502.8 paired with a SonyA7M4 or a PanasonicS52 to shoot videos. - ** In terms of the characteristics of the lens itself **: Half-frame lenses may be more affordable, lighter, and smaller. This is attractive to users who pursue cost-performance ratio, need to hold their hands for a long time to shoot (such as shooting videos with a stabiliser to reduce the burden), or need a specific focal length. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Canon half-frame lens 1585 vs 24105
In Canon's half-frame lens, there were many differences between the 15 - 85 and 24 - 105. In terms of focal length, 15 - 85 was equivalent to 25 - 120 in full frame on a half-frame machine, which had a wider angle, which made it more advantageous when shooting scenes such as landscapes. 24 - 105 had no wide-angle effect on the 38mm focal length of the half-frame machine, so it was relatively tiring to shoot scenery. In terms of image quality (mainly sharpness), if you didn't consider the focal length factor and didn't often shoot big scenes, the 24 - 105 lens performed well in sharpness, even surpassing the 24 - 702.8 lens, but the overall image quality of the two was not much different. In terms of price, in some cases (such as when both are around 5000), the price difference is not big, but the specific price fluctuations may vary according to market conditions. In terms of adaptability, 15 - 85 was much better than 24 - 105 on the half-frame machine. For example, although the aperture at the 85 end was small, the 15 - 85 focal length was more complete. It could be used as a camera head for travel and other scenes. If the requirements for wide-angle scenery were high, then 15 - 85 was a better choice; if you could accept the disadvantage of 24 - 105 without wide-angle on the half-frame machine, and pay more attention to its performance in terms of sharpness, you could also consider 24 - 105. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can a half-frame camera shoot with a full-frame lens?
Half-frame cameras could use full-frame lenses to shoot, but there were some problems and limitations. Due to the small sensor of the half-frame camera, the actual shooting angle would be narrowed by about 1.5 times or 1.6 times. For example, a 50mm full-frame lens was equivalent to a 75mm or 80mm lens on the APS-C camera. This had a significant impact on wide-angle shooting, which would weaken the wide-angle effect and limit the shooting of large scenes and buildings. Although the focal length of the full-frame lens was longer due to the equivalent focal length, it would not obtain an additional shallow depth of field effect. It might be difficult to achieve a soft background blurring effect in portrait photography. Moreover, the high sensitivity performance was determined by the camera's sensor, and using a full-frame lens would not directly improve the high Iso performance of a half-frame camera. The full-frame lens was designed to cover a larger sensor to match the full-frame body. When used in a half-frame camera, the edge of the lens would not be used, resulting in the full potential of the lens not being fully utilized, and the performance of the lens would be reduced. In terms of image quality, it mainly affected the image quality at the edge of the lens. The image quality at the center was usually unaffected (especially for wide-angle lenses), but on high-quality lenses, this effect was not significant after the aperture was reduced. When APS-C mode was turned on, it was equivalent to trimming the full-frame sensor, which would reduce the number of final images. For example, when the SonyA7R3 turned on the APS-C mode, the number of images was reduced from about 42 million to about 17.8 million. Full-frame lenses were usually larger and heavier than half-frame lenses. Mounted on a half-frame body would offset the advantages of a half-frame camera being light and portable, and full-frame lenses were more expensive, putting pressure on photographers with limited budget. In addition, the autofocus performance of the full-frame lens may be poor on the half-frame body. There may be differences in compatibility between different brands and models of lenses and the body, and problems such as slow focusing speed and reduced accuracy may affect the shooting efficiency. However, for some entry-level full-frame lenses installed on the APS-C format camera, they could basically avoid the relatively poor edge of the lens and only use the central part of the lens. The image quality was good, such as the Canon 17 - 40 red circle lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can a full-frame camera use a half-frame lens?
Full-frame cameras could use half-frame lenses, but there were some situations that needed to be considered. In terms of optical effects, when a full-frame camera uses a half-frame lens, if the APS-C format mode (similar to the trimming mode) is turned on, the equivalent focal length of the half-frame lens will change. For example, the SIGMA231.4 lens is equivalent to a 35mm lens when this mode is turned on on the full-frame A7R3. If it was not activated, there would be black circles and dark corners. Even if the dark corners could be weakened by the light circle, the black circles could still exist. In terms of pixel-wise, different full-frame cameras had different pixel-wise values after APS-C frame trimming. Generally, the original pixel-wise value was divided by 2.25 to 2.4. For example, the pixel-wise value of the Sony-A7R3 after trimming was reduced from about 42 million to about 17.8 million. In practical applications, many people chose to use a half-frame lens with a full-frame camera for the following reasons: 1. Equipment upgrade factor: Previously used APS-C micro-camera, after changing to full-frame micro-camera, the previously purchased APS-C lens can continue to be used. 2. Video shooting factors: Many cameras have a 1.5X crop (which happens to be APS-C format) when shooting a specific video format (such as 4K60P), such as the SonyA7M4, A7C2, Nikon Z62, ZF, Matsushita S5, S52, S1H, etc. Using a half-frame lens to shoot a video directly, there was no need to worry about the loss of a full-frame lens after trimming. For example, the 1.5X cropped 4K 30P of the SonyA7R5 was super-sample. For better video quality, one could also use a half-frame lens to shoot 1.5X cropped videos. The same was true for the Canon Eos R5. 3. The characteristics of the lens: In some video shooting scenes, the focal length and aperture of a full-frame lens may not be as suitable as a half-frame lens when the camera has been cropped. For example, some full-frame standard zoom lenses lost their wide angle under the camera's 1.5X crop, while half-frame lenses might have a more suitable equivalent focal length and larger aperture. However, there were certain limitations to using a half-frame lens for a full-frame camera: 1. When crop is turned on, there will be fewer pixelation, which may affect the quality of the image and the space for post-processing. 2. If the trimming mode was not turned on, there might be problems such as black circles and dark corners on the screen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
